Genetic Mutations - General Science & General Esoterism - Non-Elaborate Posts - Post 5
Microorganisms generally have higher mutation rates compared to multicellular organisms. This is due to factors such as their simpler DNA repair mechanisms and shorter generation times. Viruses, particularly RNA viruses, often exhibit the highest mutation rates due to the lack of proofreading activity in their RNA polymerases.
Organisms have evolved various DNA repair mechanisms to correct mutations and maintain the integrity of their genomes. These mechanisms include base excision repair, nucleotide excision repair, mismatch repair, and homologous recombination repair. However, the efficiency of these repair mechanisms varies among organisms, contributing to differences in mutation rates.
