Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In which process is the creating an amino acid chain using the encoded messenger RNA?
A
DNA Replication
B
Translation
C
Transcription
D
Photosynthesis
Explanation: 

Detailed explanation-1: -During translation, ribosomal subunits assemble together like a sandwich on the strand of mRNA, where they proceed to attract tRNA molecules tethered to amino acids (circles). A long chain of amino acids emerges as the ribosome decodes the mRNA sequence into a polypeptide, or a new protein.

Detailed explanation-2: -Definition. Messenger RNA (abbreviated mRNA) is a type of single-stranded RNA involved in protein synthesis. mRNA is made from a DNA template during the process of transcription.

Detailed explanation-3: -Translation of an mRNA molecule by the ribosome occurs in three stages: initiation, elongation, and termination. During initiation, the small ribosomal subunit binds to the start of the mRNA sequence.
