Which of the Following is a Representation of Gene Density

Question

Which of the following is a representation of gene density?
A)Humans have 2900 Mb per genome.
B)C) elegans has ~20 000 genes.
C)Humans have ~20 000 genes in 2900 Mb.
D)Humans have 27 000 bp in introns.
E)Fritillaria has a genome 40 times the size of a human.

Accepted Answer

Gene density refers to the number of genes present in a specific amount of DNA or genome size. Choice C states that humans have approximately 20,000 genes in 2900 Mb, indicating a higher gene density compared to other organisms with larger genomes but fewer genes (such as Fritillaria with a genome 40 times larger than humans). Choice A only gives the genome size without indicating the number of genes, choice B only gives the number of genes without context of genome size, and choice D only mentions the size of introns without providing a larger context of gene density.
