Which type(s) of RNA is(are) involved in protein synthesis?
A
Ribosomal RNA (rRNA) only
B
Messenger RNA (mRNA) only
C
Transfer RNA (tRNA) only
D
Messenger RNA (mRNA), Transfer RNA (tRNA), and Ribosomal RNA (rRNA)
Verified step by step guidance1
Understand the role of Messenger RNA (mRNA): mRNA carries the genetic information from DNA in the nucleus to the ribosomes in the cytoplasm, where protein synthesis occurs.
Learn about Transfer RNA (tRNA): tRNA is responsible for bringing amino acids to the ribosome during translation, matching the mRNA codons with the correct amino acids.
Explore Ribosomal RNA (rRNA): rRNA is a key component of ribosomes, which are the molecular machines that facilitate the assembly of amino acids into protein chains.
Recognize the collaborative function: mRNA, tRNA, and rRNA work together during translation, the process of synthesizing proteins based on the sequence of codons in mRNA.
Conclude the involvement: All three types of RNA—mRNA, tRNA, and rRNA—are essential for the process of protein synthesis, each playing a distinct and crucial role.
