Answer
This statement is incorrect because the genome includes both coding and non-coding DNA sequences. The genome is a complete set of genetic material, which encompasses more than just non-coding regions.
Step 2
B. be an uninterrupted, circular sequence of DNA base pairs.

Answer
This is also incorrect. Although some organisms, like bacteria, have circular DNA, eukaryotic genomes, including that of the gibbon, are linear and consist of multiple chromosomes.
Step 3
C. be identical to the genome of the black-crested gibbon, Nomascus concolor.

Answer
This statement is false. While the genomes of related species may share similarities, they are not identical due to variations accumulated over evolutionary time.
Step 4
D. consist of all the genetic sequences within the haploid cells of individuals of the species.
