Spontaneous mutation refers to a genetic alteration that occurs naturally in the DNA without any external influence. It results from errors during DNA replication or from spontaneous changes in the DNA structure over time. These mutations can occur randomly and spontaneously in the cells of an organism. Spontaneous mutations are typically low in frequency and may not have a specific cause or trigger.
On the other hand, induced mutation is a genetic alteration that is intentionally induced or caused by external factors or agents. These factors can include exposure to certain chemicals, radiation, or other mutagenic agents such as certain drugs or environmental toxins. Unlike spontaneous mutations, induced mutations have a triggering event that causes changes in the DNA sequence. Induced mutations are often studied in the laboratory to understand the effects of specific mutations on genes and organisms.
In summary, spontaneous mutations occur naturally and randomly without any external influence, while induced mutations are deliberately caused by exposure to mutagenic agents or environmental factors.
