A. Intergenic sequences make up >60% of the human genome. Where do these intergenic sequences come from?

B. What are some of their functions?

a. May encode mRNAs

b. May encode miRNAs

c. May be nonfunctional sequences

d. May serve as regulatory sequences for transcription

Solution

A)Intergenic regions are short -coding regions that are found with in genes iin eukaryotic organisms. It is one of the DNA sequences sometimes referred to as junk DNA, Intergenic regions are a subset of noncoding DNA. these intergenic dna consists of parasitic dna regions of transposable elements.An Intergenic sequence is a stretch of DNA sequences located between genes.Intergenic regions are a subset of noncoding DNA. some intergenicDNA acts to control genes.

B) d)May serve as regulatory sequences for transcription
