Question

Which of the following RNA takes part in the synthesis of proteins?

• A. mRNA
• B. rRNA
• C. tRNA
• D. All of these

Answer 1

The correct option is D

All of these

The correct option is D.

The explanation for the correct option:

1. The RNAs participating in protein synthesis are m-RNA, rRNA, and t-RNA.
2. Messenger RNA (mRNA) is created during transcription from a DNA template.
3. The function of mRNA is to transport protein information from DNA in a cell's nucleus to the cytoplasm, where the machinery responsible for making proteins reads the mRNA sequence and converts each three-base codon into an amino acid that belongs to a growing protein chain.
4. Ribosomal RNA (rRNA) is part of the ribosome.
5. The rRNA binds to messenger RNA and transfers RNA to enable the proper translation of the mRNA's codon sequence into proteins' amino acid sequence.
6. Amino acids are transported to the ribosomes by transfer RNA (tRNA) molecules during protein synthesis.

Final answer: mRNA, tRNA, and rRNA take part in protein synthesis.
