Question

How mutations in dna can affect an expressed trait of an individual?

Answer 1

To function correctly, each cell depends on thousands of proteins to do their jobs in the right places at the right times. Sometimes, gene mutations prevent one or more of these proteins from working properly. By changing a gene’s instructions for making a protein, a mutation can cause the protein to malfunction or to be missing entirely. Mutation in the DNA will cause the amino acids to code for a different protein, creating a new structure, therefore altering the phenotype
