Question

Factors that can increase mutation rates are

Answer 1

Mutations can be caused by spontaneous errors during DNA replication or exposure to mutagens in the environment, such as radiation and chemicals. Age and the presence of mutated promoters can also affect mutation rates.

Step-by-step explanation:

Mutations can be caused by spontaneous errors during DNA replication or by exposure to mutagens in the environment. Mutagens are factors such as radiation and chemicals that can increase the rate of mutation. Some examples of mutagens include UV radiation, tobacco smoke, and certain chemicals. Mutations can also be influenced by factors such as age and the presence of mutated promoters. Overall, mutations can result from a combination of genetic and environmental factors.

Answer 2

There are three main factors that affect the mutation rates in an organism. The three are:
1. Frequency of Primary Changes in DNA
2. Probability of Repair
3. Probability of Recognition
