Detailed explanation-1: -Translation, the second step in getting from a gene to a protein, takes place in the cytoplasm. The mRNA interacts with a specialized complex called a ribosome, which “reads” the sequence of mRNA nucleotides. Each sequence of three nucleotides, called a codon, usually codes for one particular amino acid.
Detailed explanation-2: -The sequence of basis on the DNA molecule is what directs the sequence of amino acids in the protein molecule-that’s how it all links together! So, the sequence of bases in DNA codes for the sequence of amino acids of a protein.
Detailed explanation-3: -To manufacture protein molecules, a cell must first transfer information from DNA to mRNA through the process of transcription. Then, a process called translation uses this mRNA as a template for protein assembly.
