Final answer:
There are two general categories of repair mechanisms for spontaneous mutations: DNA repair mechanisms and recombination. This process involves using the unmodified complementary strand or the sister chromatid as a template to restore the original DNA sequence.
Step-by-step explanation:
Repair mechanisms for spontaneous mutations can be categorized into two general categories:
- DNA Repair Mechanisms: There are several pathways involved in DNA repair, including Base Excision Repair, Nucleotide Excision Repair, and Homologous Recombination. These mechanisms help correct specific types of damage to DNA, such as incorrect bases or damaged nucleotides.
- Recombination: Cells can also use recombination to repair DNA damage.
- This process involves using the unmodified complementary strand or the sister chromatid as a template to restore the original DNA sequence.
