प्रश्न

Which of the following are the functions of RNA?

उत्तर

All of the above

Explanation:

RNA performs several vital roles in the cell depending on its specific type. As messenger RNA (mRNA), it carries genetic instructions from the DNA to the ribosomes, where proteins are made. As transfer RNA (tRNA), it acts as a bridge by bringing specific amino acids to the ribosome to build the protein chain. Finally, as ribosomal RNA (rRNA), it serves as a core structural and functional part of the ribosome itself.
