FAQs

Question: What are the main types of RNA?
Answer: The main types of RNA are messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA), each serving distinct roles in protein synthesis.

Question: How does RNA structure differ from DNA structure?
Answer: RNA is single-stranded and contains uracil instead of thymine, while DNA is double-stranded and contains thymine.
