15. Why might the cricket genome have eleven times as many base pairs as that of Drosophila melanogaster? a. Crickets have higher gene density. b. Drosophila are more complex organisms. c. Crickets must have more noncoding DNA. d. Crickets must make many more proteins.

Respuesta :

The cricket genome might have eleven times as many base pairs as that of the Drosophila melanogaster because crickets must have more non-coding DNA. So the correct option is C.

What is non-coding DNA?

Non-coding DNA is that portion or portions of the human genome that do not code for any of the amino acids. The amino acids are the structural unit of proteins.

Sometimes a few types of non-coding DNA sequences can have some functional roles. For example, they help in the regulation of gene expression. Mostly, non-coding DNA is not known to have any function.

The human genome is extremely vast and has 3.3 billion nucleotides. However, a very small fraction of that accounts for the coding regions. This is only about 2%.

Therefore the correct option is C.
