What term describes a substance that increases the rate of mutations by altering DNA?

Explanation:
A mutagen is a substance that increases the rate of mutations by altering DNA. These agents can be chemicals that modify DNA bases or interfere with replication, or physical factors like UV light that damage DNA and cause errors during replication. This damage or interference leads to mutations more often than would occur normally. In contrast, an enzyme is a catalyst for a biochemical reaction, not defined by increasing mutation rates; a substrate is simply the molecule an enzyme acts on; and a lipid is a fat-like molecule involved in membranes and energy storage, not specifically linked to mutagenic effects.
