Questions and Answers

What is the role of DNA in instructing the cell?

DNA carries a code that instructs the cell about the type of protein it should make.

Explain the significance of the genetic code being a triplet code.

The genetic code being a triplet code means that every three bases indicate one amino acid.

How does the sequence of bases in a gene influence protein synthesis?

The sequence of bases in a gene is the genetic code for putting together amino acids in the correct order to make a specific protein.
