Proteins are the workhorses of the cell, and responsible for many functions that keep the cell alive. The instructions for how to make each protein are encoded in the cell's DNA. Explain how DNA sequences can serve as instructions for building a protein
What will be an ideal response?
DNA sequences encode specific genes. The gene sequence contains the instructions for building a protein. These instructions are first transcribed into messenger RNA. During the process of translation, the mRNA sequence is used to assemble amino acids to make the protein. The original DNA sequence and then the corresponding mRNA sequence is therefore used to instruct which amino acids are needed and in what order they will be added, when making the protein.
