The genetic instructions for forming a polypeptide chain are carried to the ribosome by the
|
|
tRNA
|
|
|
rRNA
|
|
|
mRNA
|
|
|
DNA
|
Explanation:
Detailed explanation-1: -The mRNA is then pulled through the ribosome; as its codons encounter the ribosome’s active site, the mRNA nucleotide sequence is translated into an amino acid sequence using the tRNAs as adaptors to add each amino acid in the correct sequence to the end of the growing polypeptide chain.
Detailed explanation-2: -translation – the process in which a cell converts genetic information carried in an mRNA molecule into a protein.
