AIt carries the correct amino acid to the synthesis site
BIt carries the message out of the nucleus to the ribosome
CIt aligns the ribosome subunits around the message strand
DIt blocks the message so no protein product is ever made
Answer & Solution
Correct answer: A. It carries the correct amino acid to the synthesis site
1. Transfer RNA is one of the smallest of the four types of RNA, usually 70 to 90 nucleotides long.
2. It carries the correct amino acid to the site of protein synthesis.
3. Base pairing between the tRNA and the mRNA is what ensures the correct amino acid is inserted.
4. Carrying the message out of the nucleus is the work of messenger RNA.
5. Blocking a message describes microRNA, which regulates gene expression by interfering with mRNA.
