WebMar 22, 2024 · A segment of DNA that codes for the cell’s synthesis of a specific protein is called a gene. DNA replicates by separating into two single strands, each of which serves as a template for a new strand. The new strands are copied by the same principle of hydrogen-bond pairing between bases that exists in the double helix. WebA - Lecithin - a component of cell membrane. 3.
