Does the entire strand of DNA undergo protein synthesis or only a part of the DNA? Explain your answer and make sure you use the word "gene".

Only a part of the DNA undergoes protein synthesis. This part is called a gene. A gene is a specific sequence of DNA that contains the instructions for making a specific protein. It is responsible for determining the traits and characteristics of an individual. Only the genes that are actively being expressed are used in protein synthesis, while the rest of the DNA remains inactive and does not participate in this process.
