What are the two major mechanisms by which bacterial populations generate genetic diversity

Biology

kvv77 [185]3 years ago
5 0

<u>Answer:</u>

<em>The two major processes by which bacterial populations produce genetic diversity are gene transfer and mutation.</em>

<u>Explanation:</u>

Gene transfer in bacteria occurs through conjugation. In the process of conjugation, the plasmid gets transferred from bacteria to another. Mitosis leads to the formation of two identical individuals.

In this process, the chromosome and the DNA content of the daughter cell remains the same as the mother cell. Bacteria also divides by the process of binary fission.

A DNA fragment with the sticky end sequence TGGCA will bind with another DNA fragment with the sticky end sequence _____
klio [65]

Answer:

A DNA fragment with sticky end sequence TGGCA will bind with another DNA fragment with sticky end sequence ACCGT.

Explanation:

When a DNA strand is separated by the restriction endonuclease, it forms two separate single strands. These strands or cuts are known as sticky ends as they are detached from the complementary pairs.

These cuts of DNA are without complementary pairs and when they find suitable base pair, they get attached to it. These sticky ends are allowed to fix with the complementary base pairs during PCR/ polymerase chain reaction.

They are called sticky ends as they are ready to stick with the complementary base pairs of nucleotides.

What type of selection affects traits that influence an individual's chances to find a mating partner or be chosen as a mating p
melamori03 [73]

Answer:

Sexual selection

Explanation:

It is sexual selection because it is a type of natural selection in which an organism or organisms acquire traits which help the individual to be choose as a mating partner or to have preference for a mating partner or for competition among one sex organisms in which a traits succeed.

Sexual selection can be intrasexual or or intersexual. Intrasexual is is competition between one sex of the same organism and intersexual is between sexes of different organism.

A particular gene has two alleles, a dominant allele A and a recessive allele a. The frequency of allele A is 0.55. If the popul
bezimeni [28]

If p = frequency of A and q = frequency of a, then assuming H-W equilibrium we have

p + q = 1   ⇒   q = 1 - p = 1 - 0.55 = 0.45

Then the expected frequency of the heterozygous genotype Aa is 2pq = 2 • 0.55 • 0.45 = 0.495.
