Detailed explanation-1: -Thus, the sequence of amino acids in a protein is determined by the order of triplet base pairs in the gene for that protein on the DNA molecule. The process of turning coded genetic information into a protein involves transcription and translation.

Detailed explanation-2: -Each strand of DNA is formed of four basic building blocks or ‘bases’: adenine (A), cytosine (C), guanine (G) and thymine (T). The order, or sequence, of these bases determines our unique genetic code and contains the instructions for producing molecules in our bodies.

Detailed explanation-3: -Most genes contain the information needed to make functional molecules called proteins. (A few genes produce regulatory molecules that help the cell assemble proteins.) The journey from gene to protein is complex and tightly controlled within each cell.

Detailed explanation-4: -Answer and Explanation: Gene expression determines which proteins a cell makes. The process of gene expression involves turning on or off transcription of different genes in the genome. This means that in any given cell, only some of the genes in the genome are actively being transcribed and translated to protein.
