Question

The genomes of a number of organisms, including humans, have now been characterized and compared. Which of the following describes one of the findings of these endeavors?

(A) There is a correspondence between the biological complexity of an organism and the amount of noncoding DNA.
(B) There is a correspondence between the biological complexity of an organism and the amount of coding DNA.
(C) There is a correspondence between the biological complexity of an organism and the number of chromosomes.
(D) There is no correspondence between the biological complexity of an organism and the amount of coding DNA, noncoding DNA, or the number of chromosomes.

Answer 1

The correct answer is option a)Comparing genomes of different organisms has revealed a correspondence between biological complexity and the amount of noncoding DNA.

Step-by-step explanation:

One of the findings of comparing the genomes of different organisms is that there is a correspondence between the biological complexity of an organism and the amount of noncoding DNA. Genome size, which includes non-coding DNA, can vary greatly among species. For example, humans have a larger genome size compared to simpler organisms like bacteria. The presence of a larger amount of noncoding DNA in more complex organisms suggests that it plays a role in the regulation of gene expression and the development of complex traits.

Therefore , the correct answer is A) There is a correspondence between the biological complexity of an organism and the amount of noncoding DNA
