Scientists have discovered homeotic genes in many kinds of organisms, including fruit flies, mice, and humans. These homeotic ge
love history [14]

Answer:

D

Explanation:

The presence of homeotic genes shows that all of the listed organisms (mice, flies, humans etc) all evolved from a common ancestor.

(A) is wrong as the evidence of the same gene existing in vastly different species shows the evolutionary relationship between these organisms.

(B) is wrong as there is insufficient evidence to prove that flies are the precessor of humans. We do know that flies and humans have evolved from a common ancestor though.

(C) is non-conclusive as the passage said nothing about the gene allowing the species to have a higher chance of surviving and reproducing. Hence, an errornous claim.

(D) is the correct answer as from a common ancestor, all of the listed organisms undergo and accumulates mutation, undergoes selective pressures that resulted in divergent evolution (aka branching evolution that results in many noval species forming) after millions of years.

If you mix the Pattersonase gene sequence with EcoRI, how many
miv72 [106K]

Answer:One EcoRI site can be found in 4096 bp.As EcoRI can not cut a sequence if it is not complete, so 732421 recognition sites in human genome can be found. As you know human genome is linear genome, and when you digest it with Restriction Endonuclease having one recognition site, it always gives two fragments.
