region on DNA sequence to initiate direction until it reaches a binds at transcription. The mRNA is synthesized in a sequence on DNA is the conversion of mRNA into an amino acid polypeptide (protein) 13. 14. The following picture shows all the main components required for protein synthesis. Name each of the following components from 1-5 and briefly state their function in translation. 5. DNA mRNA 2. 1. Translation Protein A UG 3. Solution Ans 12 : RNA polymerase binds at promoter region on DNA sequence to initiate transcription. The mRNA is synthesized in a 5\' to 3\' direction until it reaches a terminator sequence on DNA. The RNA polymerase is a very crucial factor that marks the beginning of production of mRNA sequence from DNA , the process called as transcription. This RNA then codes for the amino acids which produces protein for the body. .
