Which of the following best describes mutagenesis?
The process of DNA replication
The creation of new mutations in DNA
The repair of damaged DNA
The synthesis of new DNA strands
Mutagenesis is the process by which genetic mutations are induced or created in the DNA sequence. Mutations are alterations in the DNA sequence that can arise spontaneously or be induced by external factors such as radiation, chemicals, or other environmental agents.
Mutagenesis can occur naturally as a result of errors during DNA replication, or it can be induced by mutagenic agents such as chemicals, UV radiation, or X-rays. Induced mutagenesis is commonly used in research to create specific mutations in genes for studying their effects on biological processes.
Option b is the correct answer.
