If Messelson & Stahl had stopped their experiment after growing the bacteria for only one generation in light nitrogen (N14), what could they have concluded about the mechanism of DNA replication?
A. DNA replication is semi-conservative
B. DNA replication is conservative
C. DNA replication is dispersive
D. DNA replication is not conservative
E. DNA replication is not dispersive

Answers

Answer 1

If Meselson and Stahl had stopped their experiment after growing the bacteria in light nitrogen (N14) for just one generation, they would have concluded that DNA replication is conservative and DNA replication is divergent from the mechanism of DNA replication. Here options B and C are the correct answer.

If Meselson and Stahl had stopped their experiment after growing the bacteria for only one generation in light nitrogen (N14), they would have observed a single band in the centrifuge tube, indicating that all of the DNA in the bacteria contained only the light isotope. This result would not have allowed them to conclude definitively about the mechanism of DNA replication.

However, they could have eliminated the conservative and dispersive models of replication because in conservative replication, there would be one band of entirely heavy DNA and one band of entirely light DNA, and in dispersive replication, there would be a single band with DNA containing both heavy and light isotopes.

Therefore, they could have eliminated options B and C, respectively. They could not eliminate the semi-conservative or non-conservative mechanisms, so no conclusive determination could have been made about the mechanism of DNA replication.

A) GACTG
B) UGACU
C) AGTUG
D) GACUG
E) GACGU

Answers

GACUG would be the complementary messenger RNA strand that is generated from the DNA base sequence CTGAC.

D is the proper answer.

RNA polymerase, the main enzyme in transcription, builds a complementary strand of RNA using a template consisting of single-stranded DNA. In order to build an RNA strand, RNA polymerase selectively adds each new nucleotide to the 3' end of the strand as it travels from 5' to 3'.

In DNA, adenine (A) always forms a base-pairing pair with thymine (T), whereas in RNA, it forms a base-pairing pair with uracil (U). On the other hand, DNA and RNA both link guanine with cytosine.

Why is the rumen not acidic?​

Answers

Answer:

please make me brainalist

Explanation:

To keep the rumen bugs happy, cows chew cud. Chewing cud creates saliva, which has bicarbonate in it and opposes acid. Therefore, the more the cows chew cud, the more saliva they produce, and this saliva when swallowed with the cud maintains a rumen pH between 6.0 and 7.0, keeping the important microbes happy.

Answer: How come the rumen is not acidic? Rumen bacteria quickly break down carbohydrates in the rumen into sugars, which are subsequently fermented to produce an excess of volatile fatty acids (VFAs), lowering the rumen's pH. In what way do ruminants and rumen microorganisms interact?

2. (b) Describe TWO environmental benefits of urbanization.

Answers

Answer:

Urbanization refers to the process of people moving from rural areas to urban areas, leading to the growth of cities and towns. While urbanization is often associated with negative environmental impacts, such as pollution and habitat destruction, there are also some potential environmental benefits:

Reduced land use: By concentrating people and development in urban areas, urbanization can help to reduce the amount of land that needs to be converted for agricultural or natural ecosystems. This can help to protect biodiversity and reduce the amount of habitat destruction that occurs due to human activities.

Efficient use of resources: In many cases, urban areas are more efficient in their use of resources than rural areas. For example, people in cities often use less water and energy per capita than people in rural areas, due to the more efficient design of urban infrastructure and buildings. This can help to reduce the environmental impact of human activities, including greenhouse gas emissions and other forms of pollution.

Set the light level to 0 to monitor plant cellular respiration. The simulation will execute immediately whenever a variable is modified.

Aquatic plants, like land plants, engage in photosynthesis and internal metabolism. When marine autotrophs release oxygen as a result of photosynthesis, it dissolves in water. Dissolved oxygen can be detected directly to determine whether aquatic plants engage in photosynthesis or cellular respiration under various circumstances.

Finding a consistent supply of aquatic plants can be challenging because some species are only accessible periodically and others are invasive. As a result, for this novel exercise,We suggest Java moss (Vesicularia dubyana) or Christmas moss (Vesicularia montagnei), two watery aquaria-friendly aquatic bryophytes. As evidenced by our findings, Java moss experiences cellular respiration in the dark, resulting in a decrease in dissolved oxygen, and rapidly changes to photosynthesis when subjected to an LED or halogen plant light. Using this tough aquatic plant, students can simply adjust light levels to learn more about photosynthesis and cellular respiration.

When there is a genotype that consists of a dominant and a recessive allele, the phenotype generally looks like the dominant one.

Answers

Yes, when there is a genotype consisting of a dominant and a recessive allele, the phenotype is generally the same as the dominant allele.

This is because the dominant allele has a greater effect on the phenotype than the recessive allele, and it is the trait that is expressed when both alleles are present. For example, if the genotype is heterozygous for the trait of eye color, the phenotype will usually look like the dominant eye color (e.g. blue) rather than the recessive one (e.g. brown). This is because the dominant allele is what is expressed when the two alleles are present in the same genotype. In some cases, however, both alleles can be expressed, resulting in a blended phenotype.

Select all the DNA sequences required for the replication and segregation of eukaryotic chromosomes. The following DNA sequences are required for the replication and segregation of eukaryotic chromosomes: Telomeres at the ends of chromosomes, Centromeres Origins of replication.

The initiation of DNA replication begins at specific sites on the chromosomes known as the origins of replication. Origin recognition complexes (ORC) are multisubunit protein complexes that bind to specific sites on chromosomes and recruit other proteins to form a pre-replication complex (pre-RC). The pre-RC assembles and activates DNA helicases, which separate the two strands of DNA at the origin of replication, forming a replication fork. The DNA polymerase complex binds to the replication fork, synthesizes new strands of DNA in the 5' to 3' direction, and discontinuously elongates the strands. The synthesis of the two strands of DNA continues until they meet at another specific site on the chromosome. The formation of two new DNA molecules is then complete. The telomeres are protective structures at the ends of chromosomes. Telomeres are repetitive DNA sequences, composed of TTAGGG repeats, which form a cap-like structure at the ends of chromosomes.

They protect the chromosome ends from being degraded or fused with other chromosomes. Centromeres are the constricted regions of chromosomes that attach to spindle fibers during cell division. They are essential for the correct separation of chromosomes during cell division. The origin of replication is a specific site on the chromosome where DNA replication begins. The origins of replication occur at specific sites on chromosomes, and the initiation of replication is tightly regulated.

A farmer wanted to control wind erosion across a 1200 foot field. The wind blows predominately in that direction (i.e., across the 1200 foot field). She decided to plant a windbreak that would be 20 ft tall at maturity. How many windbreaks should she plant, assuming that the windbreaks are perpendicular to the predominate wind direction? Recall from the Lecture 7 slides that the downwind area protected by a tree is 20 times greater than the height of the tree.
