DNA MAKES RNA MAKES PROTEIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The function of tRNA is to ____
A
produce a copy of mRNA
B
break the hydrogen bonds of DNA
C
transfer amino acids during translation
D
separate sister chromatids
Explanation: 

Detailed explanation-1: -Transfer RNAs (tRNAs) are adaptor molecules that translate genetic information into protein sequence by delivering amino acids to the protein synthesis machinery during translation.

Detailed explanation-2: -tRNA carries and transfers an amino acid to the polypeptide chain being assembled during translation. translation – the process in which a cell converts genetic information carried in an mRNA molecule into a protein.

Detailed explanation-3: -During translation, these tRNAs carry amino acids to the ribosome and join with their complementary codons. Then, the assembled amino acids are joined together as the ribosome, with its resident rRNAs, moves along the mRNA molecule in a ratchet-like motion.

Detailed explanation-4: -tRNAs (transfer RNAs) carry amino acids to the ribosome. They act as “bridges, ” matching a codon in an mRNA with the amino acid it codes for.

Detailed explanation-5: -The prime function of tRNA is to transfer amino acids to form the right sequence of the polypeptides. Hence, it assists protein synthesis. It also functions as an adapter molecule to link specific amino acids to the respective codons located in the mRNA molecules. Every amino acid defines a particular tRNA.
