The Comparison Between the Number of Human Genes and Those

The comparison between the number of human genes and those of other animal species has led to many conclusions, including which of the following?

A) The number of proteins expressed by the human genome is far more than the number of its genes.
B) More than half of the human genome is composed of genes that are transcribed and then translated into protein.
C) The density of the human genome is far higher than in most other animals.
D) The genomes of most other organisms are significantly smaller than the human genome.
E) Most human DNA consists of genes for protein, tRNA, rRNA, and miRNA.
