Text Solution

AI Generated Solution

### Step-by-Step Solution: 1. **Understanding mRNA (Messenger RNA)**: - mRNA is a type of RNA that carries genetic information from DNA to the ribosome, where proteins are synthesized. It is synthesized during transcription and contains the codons that dictate the sequence of amino acids in a protein. 2. **Role of mRNA in Translation**: - The mRNA serves as a template for translation. Each codon (a sequence of three nucleotides) on the mRNA corresponds to a specific amino acid or a stop signal during protein synthesis. The ribosome reads the mRNA sequence in the 5' to 3' direction to assemble the amino acids into a polypeptide chain. ...
