Solution

The correct option is D tRNA molecules carry specific nucleotides to the mRNA and ribosomes during protein synthesis.
The mRNA encodes for a protein as contiguous codons in a series each of which is recognised by a particular tRNA. One end of the tRNA matches the genetic code in a three - nucleotide sequence called the anticodon. The anticodon base pairs with a codon in mRNA during protein biosynthesis and picks up specific amino acid from the cytoplasm to ribosome during protein synthesis. Thus, the correct answer is option C.
