Detailed explanation-1: -Messenger RNA (mRNA) serves as the intermediary between DNA and the synthesis of protein products during translation. Ribosomal RNA (rRNA) is a type of stable RNA that is a major constituent of ribosomes.
Detailed explanation-2: -In the first step, the information in DNA is transferred to a messenger RNA (mRNA) molecule by way of a process called transcription.
Detailed explanation-3: -RNA acts as the information bridge between DNA and protein. mRNA is the message that carries genetic information from the DNA in the nucleus to the cytoplasm. tRNA is the adaptor that reads the mRNA and brings the amino acids to the ribosomes for protein synthesis.
Detailed explanation-4: -To ‘read’ these blueprints, the double-helical DNA is unzipped to expose the individual strands and an enzyme translates them into a mobile, intermediate message, called ribonucleic acid (RNA). This intermediate message is called messenger RNA (mRNA), and it carries the instructions for making proteins.
Detailed explanation-5: -Ribosomal RNA (rRNA) rRNAs combine with proteins and enzymes in the cytoplasm to form ribosomes, which act as the site of protein synthesis. These complex structures travel along the mRNA molecule during translation and facilitate the assembly of amino acids to form a polypeptide chain.
