Why can damage to dna affect a person's ability to produce enzymes?

There you go below

Explanation:

DNA damage occurs continuously as a result of various factors—intracellular metabolism, replication, and exposure to genotoxic agents, such as ionizing radiation and chemotherapy. If left unrepaired, this damage could result in changes or mutations within the cell genomic material.

many genes code for enzymes.  Damage to those sections of DNA can damage the genes so that enzymes can either fail to be manufactured altogether or they are made with the incorrect amino acid sequence which can then affect their function. The 3 dimensional structure of enzymes are very important for proper function. Changes in the amino acid sequence may change the structure of such enzymes, making them non-functional u M^F.
