Correct option (c) mRNA
Explanation :
mRNA is messenger RNA which brings coded information from DNA and takes palt in its translation by arranging amino acids in a particular sequence during the synthesis of the polypeptide. However, the codon of mRNA is not recognised by amino acids but by anticodons of their adaptor molecules (tRNA→aa tRNAs). Translation occurs over the ribosomes. The same nRNA may be used again and again. In the form of polysorne, it can help in the synthesis of a number of copies simultaneously.
