Which of the following statements best compares genetic diversity in eukaryotes and prokaryotes?

Biology
1 answer:
cestrela7 [59]3 years ago
5 0

Answer:

C. Mutations increase the genetic diversity in both prokaryotes and eukaryotes.

Explanation:

It is a well-established fact that mutations increase the genetic diversity in living organisms (especially if they are positive mutations). The positive and faster mutations will help the organism to develop better traits for survival in the changing environments.

The other options are incorrect because of the following reasons:

A. Eukaryotes don't do gene transfer via conjugation.

B. Eukaryotic species don't experience a greater rate of mutations as compared to the prokaryotes. Prokaryotes have a faster mutation rate. This is the reason that microbes can adapt to changing environments faster than humans or other multicellular organisms.

D. As mentioned above, sexually reproducing eukaryotic species evolves slower than the asexually reproducing species. For example, evolution in bacteria (e.g. drug resistance) is faster than any organism belonging to eukaryotic lineage.

How can humans reduce the amount of endangered and extinct species?
Andrews [41]
There are many ways humans can reduce the amount of endangered and extinct species. However, I would say by reducing pollution and logging/mining. Nearly 318 species have become extinct due to pollution. The reduction of carbon emissions would be a good way to curb the amount of pollution produced by humans.

A standard PCR cycle includes three steps: denaturation (95°C), annealing (55°C), and elongation (65°C).
xz_007 [3.2K]

Answer:

Denaturation process: The DNA template  

Annealing process: Primers  

Elongation process: dNTPs and Taq polymerase

Explanation:

For the denaturing process, the only ingredient that is required is the DNA template that will be separated from a double helix (or double strand) into a single strand, by increasing the temperature to 95 C, (at this temperature the hydrogen bonds that keep together the double stranded break). After the double strand is denatured, the following process is annealing. For this, the required ingredient are the primers; these primers will hybridize or anneal according to the nucleotide complementarity to the single strand of the DNA. Finally, for the Elongation process, you will require the Taq polymerase and the dNTPs. The enzyme will synthesize or “generate” a new strand of DNA based on the DNA template, using the provided dNTPs in the direction 5’ to 3’.

I hope this clarify you inquiry.
