Answer:
messenger RNA (mRNA)
Step-by-step explanation:
mRNA or messenger RNA is one of the three types of RNA molecules (the other being tRNA and rRNA) that is specifically responsible for carrying genetic information previously encoded and stored in the DNA into the ribosomes for translation to occur.
The process of translation results to the synthesis of amino acid sequences, which make up a polypeptide. Hence, it can be said that mRNA is that type of RNA that acts as a temporary copy of DNA's instructions and provides details on how to assemble a polypeptide chain.
