8. Describe the processes of transcription and translation.




9. What are mutations and how do they increase the genetic variation within a species?




10. What is DNA fingerprinting?

Answers

Answer:

The answer will be listed below.

Explanation:

1.)-

a.) G1 Phase- Following cytokinesis, during G1 phase the cells monitor environment for the potential growth factors, grow larger and once achieve the threshold size then starts the progression through S phase.

b.) S Phase- To produce two similar daughter cells, the complete DNA instructions in the cell must be duplicated. DNA replication occurs during this S phase.

c.) G2 Phase- During the gap between DNA synthesis and mitosis, the cell will continue to grow and produce new proteins. At the end of this gap is another control checkpoint to determine if the cell can now proceed to enter Mitosis and divide.

d.) Mitosis- Prophase, Metaphase, Anaphase, and Telophase occurs in Mitosis. During prophase, the parent cell chromosomes, which were duplicated during S phase, condense and become thousands of times more compact than they were during interphase.

Metaphase is a stage in the cell cycle where all the genetic material is condensing into chromosomes. As metaphase continues, the cells partition into the two daughter cells.

Anaphase- In anaphase, the sister chromatids separate from each other and are pulled towards opposite ends of the cell. The protein that holds the sister chromatids together is broken down, allowing them to separate.

During telophase (the final stage), the chromosomes arrive at the cell poles, the mitotic spindle disassembles, and the vesicles that contain fragments of the original nuclear membrane assemble around the two sets of chromosomes.

e.) Cytokinesis- During cytokinesis, the cytoplasm splits in two and the cell divides.

2.) They go through the process of Mitosis. Mitosis consists of four steps: Prophase, Metaphase, Anaphase, Telophase.

3.) Mitosis takes place all over the body, while meiosis only takes place in the sex organs and produces sex cells. Mitosis consists of one stage whereas meiosis consists of two stages. Mitosis produces diploid cells, whereas meiosis produces haploid cells. Mitosis produces two identical daughter cells whereas meiosis produces four genetically different daughter cells.

A similarity between mitosis and meiosis is that they both produce new cells and start with one a single parent cell to duplicate.

4.) Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits.

5.) The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment.

6.) A genotype refers to the genetic characteristics of an organism. A phenotype refers to the physical characteristics.

7.) The opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin.

8.) Transcrption-

Initiation- The DNA molecule unwinds and separates to form a small open complex.

Elongation- RNA polymerase moves along the template strand, synthesising an mRNA molecule.

Termination- In prokaryotes there are two ways in which transcription is terminated.

Processing...

Translation- Translation happens in four stages: activation (make ready), initiation (start), elongation (make longer) and termination (stop). These terms describe the growth of the amino acid chain (polypeptide).

9.) A mutation is a change in a DNA sequence. Mutations can result from DNA copying mistakes made during cell division, exposure to ionizing radiation, exposure to chemicals called mutagens, or infection by viruses. Mutation has introduce a new allele into the population that increases genetic variation and may be passed on to the next generation.

10.) DNA fingerprinting is a method used to identify an individual from a sample of DNA by looking at unique patterns in their DNA.

What is a nucleotide base?

A nucleotide is the monomer constituting DNA or RNA biopolymer molecules.

Each nucleotide consists of a nitrogenous heterocyclic base (or nucleobase), which can be either a double-ringed purine or a single-ringed pyrimidine; a five-carbon pentose sugar (deoxyribose in DNA or ribose in RNA); and a phosphate group.

The two classes of nitrogenous bases are purines and pyrimidines and they are as follows;

Purines - Adenine and GuaninePyrimidines - Cytosine, Uracil, Thymine

According to this question, Adenine and thymine are examples of nitrogenous bases.

Jamal ate a meal of rice before seeing his doctor. Rice is made of mostly starch molecules. Jamal has been feeling tired a lot, so his doctor gave his a test that found jamal’s cells contained normal levels of oxygen and low levels of glucose. Does this explain why Jamal has been feeling tired

Answers

Answer:

Yes, Jamal’s respiratory system is working, but his digestive system is not breaking down starch molecules into glucose for his cells.

Explanation:

Jamal ate a meal of rice before seeing his doctor. Jamal has been feeling tired because his body cannot breakdown the starch molecules into glucose and thus has low levels of glucose in the blood.

What is a healthy diet?

A healthy diet is a diet which maintains or improves the overall health of an individual. A healthy diet provides the body with all the essential nutrients in sufficient amount. A healthy diet contains fluids, macronutrients such as protein, micronutrients such as vitamins with adequate amount of fiber and food energy.

Jamal is eating a meal of rice before seeing the doctor. He is feeling tired. After the test, it was observed that the oxygen level is normal however he has a low level of glucose. This is because rice contains high amount of starch, which is a polysaccharide of glucose. This starch is broken down by the body into glucose units which are used by the cells in producing energy. However, Jamal's body cannot break down this starch into glucose molecules and thus show low levels of glucose molecules.

Why does cell size need to be limited?

Where does the DNA come from that is in the parent cell?

Answers

Answer:

Your genome is inherited from your parents, half from your mother and half from your father. The gametes are formed during a process called meiosis. Like your genome, each gamete is unique, which explains why siblings from the same parents do not look the same.

The need to be able to pass nutrients and gases into and out of the cell sets a limit on how big cells can be. The larger a cell gets, the more difficult it is for nutrients and gases to move in and out of the cell. As a cell grows, its volume increases more quickly than its surface area.

What is some of the evidence used by Galileo to support Copernicus’s model and disprove Aristotle and Ptolemy’s?


Each planet spins in an epicycle.

Planets appear to move backward.

Jupiter has moons orbiting it.

The religious and cultural beliefs supported this model.

Answers

Claudius Ptolemaeus (85-165 AD) or Ptolemy believed Aristotle's theory that the Sun, Moon, and planets circled the Earth.

However, he improved it to account for the fact that planets sometimes appear to travel backward across the sky, called retrograde motion.

Galileo Galilei used various pieces of evidence to support Copernicus's heliocentric model and challenge the geocentric model proposed by Aristotle and Ptolemy. Some of the key evidence and observations that Galileo put forward include:

Observations of the phases of Venus: Galileo observed that Venus goes through phases just like the Moon.Observation of Jupiter's moons: Galileo discovered four moons orbiting Jupiter, now known as the Galilean moons (Io, Europa, Ganymede, and Callisto). Observation of Saturn: Galileo observed Saturn using his telescope and noticed the presence of what he called "ears" or "appendages" on each side of the planet.Lunar observations: Galileo's observations of the Moon revealed mountains, valleys, and craters, contradicting the notion of a perfect and unchanging celestial realm put forth by Aristotle and Ptolemy.Sunspot observations: Galileo observed sunspots, dark spots on the surface of the Sun.

Thus, it's worth noting that while Galileo provided empirical evidence to support the heliocentric model, his ideas and evidence faced strong opposition from the religious and cultural beliefs of the time, as they contradicted the established dogma of a geocentric universe.
