उत्तर
Messenger RNA
Explanation:
Messenger RNA (mRNA) is a specific class of RNA that acts as an intermediary or “messenger” by carrying the genetic code from the DNA in the nucleus to the ribosomes in the cytoplasm. During the process of transcription, the DNA sequence of a gene is copied into a complementary mRNA strand, which then serves as a temporary blueprint. This mRNA sequence is organised into three-base units called codons, which the ribosome “reads” to determine the exact order of amino acids needed to construct a specific protein.
