The comparison between the number of human genes and those of other animal species has led to many conclusions,including the idea that
A)the density of the human genome is far higher than in most other animals.
B)the number of proteins expressed by the human genome is far more than the number of its genes.
C)most human DNA consists of genes for protein,tRNA,rRNA,and miRNA.
D)the genomes of other organisms are significantly smaller than the human genome.

Question

It has been found that the human genome has around 20,000-25,000 protein-coding genes, which is similar to or slightly fewer than other animals like mice or chimpanzees. However, the number of proteins expressed by the human genome is far higher than the number of its genes, due to alternative splicing and other mechanisms that produce multiple protein products from a single gene.
