Explanation:
Detailed explanation-1: -A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins.
Detailed explanation-2: -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. (Amino acids are the building blocks of proteins.)
Detailed explanation-3: -Genes are short pieces of DNA that carry specific genetic information.
