Explain what, if any, is the issue facing DNA polymerase in regards to its 5’->3’ activity when replicating DNA.

Answers

Answer:

The two strands of DNA are replicated in different ways

Explanation:

DNA replication is a process that occurs during the S phase of the cell cycle that consists of making two identical copies of the double-stranded DNA molecule, which subsequently are distributed in the daughter cells during cell division. During this process, DNA polymerase can add nucleotides in 5' to 3' direction, but not in 3' to 5' direction. In consequence, the DNA strand that has 3’ to 5’ directionality can be synthesized directly, while the DNA template strand that has 5’ to 3’ directionality can't be synthesized in a continuous manner and thereby it is created by adding small DNA fragments, which are known as Okazaki fragments (150-200 nucleotides in size).

Another has medium brown feathers with light wings. The last one has medium brown feathers with very dark wings. natural selection reproductive maturity genetic variation genetic drift Mark this and return

Answers

Answer:

genetic variation

Explanation:

Genetic variation refers to the difference in genetic content of organisms within a population. The genetic makeup of living organisms are made up of GENES, which exists in contrasting pairs called ALLELES. Each allele is responsible for variation in traits exhibited by the organisms. Differences in the allelic content of organisms of the same species leading to the display of varying phenotypic characteristics is referred to as GENETIC VARIATION.

This is the case in the example given in which four birds in a population possess a range of wing and feather colors i.e light brown feathers with darker wings, dark feathers with lighter wings, medium brown feathers with light wings, and medium brown feathers with very dark wings, all resulting from a variation in their genetic content. Hence, this is an example of GENETIC VARIATION.

identify a probable reason that the dark moths survived while the light moths did not during the industrial revolution

Answers

Answer:

directional selection

Explanation:

The directional selection is a type of Darwinian selection where a particular phenotype is favored in the population, thereby modifying the allelic frequencies to increase the proportion of the favored phenotype. Biston betularia, also known as peppered moth, is a species that was influenced by directional selection in its recent past. Before the industrial revolution, the frequency of light-colored moths was predominant compared to the darker-colored phenotypes, because this color has higher adaptive fitness in a clean, no pollution environment, thereby light-colored moths were able to avoid predatory birds. However, during the industrial revolution, the frequency of dark-colored moths increased in response to pollution (i.e. darker environment), thereby conferring a higher adaptive fitness to darker phenotypes.

How many bases are in the second fragment?

Answers

Answer:

This question seem incomplete

Explanation:

This question seem incomplete. However, if the strand of the second fragment is what is provided above, then the answer is 51

This strand/fragment is definitely a DNA strand because of the absence of uracil (U) or because of the presence of thymine (T). The four bases in a DNA are adenine (A), Thymine (T), cytosine (C) and Guanine (G). These bases also bind to one another in the pattern described below

A ⇆ T

G ⇆ C

Hence, the adenine (A) on one strand can only bind to thymine (T) on the complementary strand (and vice versa) while the guanine (G) on one strand can only bind to cytosine (C) on the complementary strand (and vice versa).

Hence, the letters seen is the question are representations of bases in a DNA strand/fragment. The number of letters/bases here are 51

Which process involves a decrease in the dispersal of matter? Select the correct answer below: heat exchange between two solids

Answers

Answer:

The options are

A.heat exchange between two solids

B.the decomposition of a compound into its constituent elements

C.the precipitation of a solid

D.none of the above

The answer is

C.the precipitation of a solid

Dispersal of matter involves the process whereby there is more space occupied by the resulting element/compound than the initial one. For example the conversion of liquid to gas means that it has an increase in the dispersal of matter as the gas particles will contain more space when compared to a liquid.

Precipitation of a solid means conversion of a liquid to a solid. A liquid is known to contain more space which means there is a decrease in the dispersal of matter.

The process that involved the reduction in the dispersal of matter should be the precipitation of a solid

What is the dispersal of matter?

It refers to the process in which it contains the additional space that should be occupied. Like the conversion of the liquid to gas represent there should be increment in the disperson of the matter since the particles of the gas comprise more space at the time when the comparison is to be done with the liquid. Here, precipitation of the solid represent the transformation of the liquid to the solid.

g The ____ ring is built onto ribose-5-phosphate of PRPP for its de-novo nucleotide biosynthesis, while the ring structure of the ______ bases are synthesized separately and then coupled to ribose-5-phosphate via the C-N glycosidic bond.

Answers

Answer:

The purine ring is built onto ribose-5-phosphate of PRPP for its de-novo nucleotide biosynthesis, while the ring structure of the pyrimidine bases are synthesized separately and then coupled to ribose-5-phosphate via the C-N glycosidic bond.

Explanation:

Purines are produced as bases attached to the ribose 5-phosphate (pentose sugar). The adenine and guanine nucleotides derive from inosine monophosphate (IMP), which is synthesized on an existing ribose-phosphate. Thus, purine bases are built on a ribose sugar that is directly attached to the pyrimidine ring. On the other hand, pyrimidines are produced from the carbamoyl phosphate precursor. In this case, the ribose-5-phosphate pentose sugar is attached after the pyrimidine ring is made.

ERV (Expiratory reserve volume)
RV (Residual volume)

Answers

Answer:

During intense exercise:

lung capacity increases

vital capacity increases

respiratory capacity increases

functional residual capacity increases

tidal volume increases

the inspiratory and expiratory reserve volumes decrease as does the residual volume.

Explanation:

Residual volumes decrease because having better lung capacity, better development of the secondary skeletal muscles that collaborate in expiration and inspiration, these are given in a better way, and more effectively.

If these processes take place more efficiently, their potentiality increases and expiration and inspiration move a large current of air into the lungs, thus leaving less reserve airs.

Those people who have increased exhalation or inspiration reserve, have a weak activity of the musculature in the processes and function as "stagnant air" which is synonymous with a lack of physical activity or aerobic capacity.

It is important to clarify that all the above processes are accompanied by an increase in the size of the chest cage

You are observing a sample of cells in the lab to determine why they did not
divide properly. You notice that the chromosomes are lined up in the middle
of the cell, and the spindle fibers have extended towards them, but have not
attached. What could be damaged?

Answers

The kinetochore of the chromosomes


Explanation:
What could be damaged that is hindering the spindle fibers from attaching to the chromosomes are the kinetochores of the chromosomes.
At the metaphase stage of the cell division, the chromosomes align at the equator of the cell and the spindle fibers engage each chromosome at a region known as the kinetochore.
The kinetochore is made up of complex proteins and lies around the centromere region of the chromosome. The microtubules of the spindle fibers attach to this region during the metaphase stage.
If the kinetochore is damaged, it means the spindle fiber will not be able to attach to the chromosome.

How does your body know when cells are missing

Answers

Answer:

Receptors provide information to nervous system about missing cells.

Explanation:

Your body know when cells are missing due to nervous system. The network of nervous system spreads throughout human body which provide information about what is going on in the body. If the cells are missing due to injury, the nervous system gives instruction to the body to produce more cells and transported that cells to the region where these cell are required. So receptors are responsible to provide information to nervous system about missing cells.

The body knows cells are missing as a result of the receptors sending

If a cusp is lost during preparation, which matrix band would provide the best support while restoring

Answers

Answer:

I would use a specialized or preformed matrix for the posterior sector.

Explanation:

Losing a cusp is a much more critical situation, that is, there will be less tooth remnant and less resistance to functional and parafunctional forces.

The matrices that are usually used in the posterior sector are matrices that must be burnished and already come with a format to better restore the functional unit of the occlusal surface.

It is important to clarify that cusps are only in the posterior sector and not in the anterior sector.

The cusps, even if they have the most correct selection of the matrix, will fail in their restoration if they are not performed according to the patient's occlusion, under a good dental integration system such as adhesion through resins, and respecting the normal antomy of the piece to be restored.

Recent research has found that on one island of the Galapagos two finch species interbred. This interbreeding may have resulted in a hybrid species that ultimately led to the extinction of one of the species Darwin discovered. They call this speciation in reverse, or despeciation. Based on what you know about speciation, why are these terms appropriate?

Answers

Answer:

Speciation is defined as an evolutionary process in which one population evolves into a distinct species.

Speciation in reverse, or despeciation is defined as the extinction of an old species due to combining with evolved species to produce hybrid species but it conserves biological lineage.

In the given research, the term used despeciation or speciation in reverse is appropriate as hybrid species resulted from interbreeding of Galapagos two finch species conserved the biological lineage but also loss one of the species Darwin discovered.

Answer:

Speciation is the method by which unique species evolve from a common ancestor. In this case, two of these species that split from a common ancestor interbred and created a hybrid. This hybrid was apparently stronger and possibly better adapted to the environment, which led to extinction of a species formed by the initial speciation event.
