Answer :
The correct answer is B
In he process called the central dogma of molecular biology information about the protein production is translated from the DNA molecule to a functional protein.
In the first step, the mRNA is transcribed from a gene on the DNA. The mRNA conians the information about the sequence of amino-acids that will build the protein.
In the ribosomes, amino acids are bound together bu the halp of ribosomal and transport RNA. After additional changes a protein is formed.
