According to the research, the correct answer is Option C. In the human genome, most of the diversity occurs in sequences that code for tRNA.
It is the changes that are registered in the genes of a species or a population where in the transfer RNA (tRNA), the molecules recognize genetic information.
In this sense, it can be produced by the combination of genes or by mutation in a deoxyribonucleic acid (DNA) sequence.
Therefore, we can conclude that according to the research, genetic variability is a consequence of the process of natural selection of a gene that codes for tRNA; then this tRNA carries a mutation.
