The correct answer to this question is E, RNA is the main component in ribosomes, tRNA, and mRNA. RNA stands for ribonucleic acid. It is in all forms of life, and it is essential to one's life. This is because it has various roles, including coding, a genes expression, and decoding.

A chain of nucleotides assembles RNA. It is single-stranded onto itself. mRNA stands for messenger RNA, which is used to send genetic information and for the synthesization of proteins. tRNA is transfer RNA, which is the link between proteins and mRNA. Ribosomes are small particles that consist of RNA and proteins.
