Correct Answer - B
In the process of protein synthesis, the messenger RNA (mRNA) is responsible for carrying the genetic code transcribed from DNA to specialised sites within the cell (called ribosomes) where the information is translated into protein. The sequence of amino acids in a particular protein is detemined by the sequence of nucleotides in mRNA . Sequence of tRNA , cDNA or rRNA do not decide the amino acid sequence in protein synthesis,
