Expert Solution
Step 1

Ribonucleic acid (RNA) also contains genetic material but rarely takes part in transferring the genes from one generation to another like DNA. Instead, it plays a vital role in ribosome and protein synthesis (translation). RNA forms in the nucleolus, and then moves to the cytoplasm. Types of RNA are, mRNA (messenger RNA), tRNA (transfer RNA) and rRNA (ribosomal RNA).
