What is the minimum number of cycles necessary to replicate a fragment of DNA over 500 times? How did u determine this?
ryzh [129]

Answer:

The correct answer is "9 cycles".

Explanation:

The minimum number of cycles necessary to replicate a fragment of DNA over 500 times is 9 cycles. In Polymerase Chain Reaction (PCR) method, the fragments of DNA are doubled in each cycle. This means that after "n" cycles, the total number of fragments is given by the equation 2^n. In this case, after 9 cycles a total of 512 DNA fragments will be obtained, because 2^9 is equal to 512.

Genetic drift tends to occur in populations that
Elina [12.6K]

Answer:

are reproductively isolated

Explanation:

The genetic drift represents a change in the frequency of an already existing gene variant in a population as a consequence of random sampling of organisms. The offspring would have the genes from their parents, and because the population is limited in numbers and it has been exposed to a new environment, the individuals with advantageous traits will survive and reproduce, while the others will die out gradually. This occurs when a small population of some species is reproductively isolated. The genetic variation is very small because of the small number of individuals, so only certain genes are passed on tot he offspring, thus resulting in gradual changes that will eventually lead to the creation of a separate species.
