The correct option is C
tRNA
tRNA
tRNA or transfer RNA carries amino acid in the amino acid acceptor arm and reads genetic code by the anticodon arm. Based on the codon that it reads on the mRNA, it brings specific amino acids and adds them to the polypeptide chain.
mRNA
mRNA or messenger RNA is formed by the process of transcription using DNA as the template. mRNA then acts as a template for synthesis of proteins.
rRNA
rRNA is the structural component of ribosomes and is catalytic in function, helping in translation.
hnRNA
In eukaryotes, the primary RNA transcript is known as heterogeneous nuclear RNA or hnRNA. It undergoes post-transcriptional modification in the nucleus to become a mature mRNA.
