The human genome includes all the DNA found in all of our chromosomes. Rank these parts of the human genome form highest percentage of our total DNA to lowest percentage of our total DNA: (a) DNA that is identical in all humans, (b) DNA that is not identical in all humans, (c) DNA that contains instructions for making proteins, (d) repeat sequences.

Option B, The human genome is the genome ie the DNA sequence contained in 23 pairs of chromosomes is not identical in all humans, the 23 pairs, 22 are autosomal chromosomes and a sex-determining pair (two female Xen chromosomes, and an X and Y in males). The DNA sequence forming the human genome contains the coded information necessary for the highly coordinated and environmentally adaptable expression of the human proteome, ie, of the human proteins as a whole.
