CHAPTER 4: DNA damage and repair（DNA损伤与修复） •Molecular Biology Course 4 teaching hours
The consequence of high rates of mutation ■ Mutation in germ cell(生殖细胞)would destroy the species ■Mutation in somatic cell(体细胞)would destroy the individual. Maintenance of the correctness of the DNA sequence is definitely crucial for living organisms
The consequence of high rates of mutation ◼ Mutation in germ cell (生殖细胞) would destroy the species ◼ Mutation in somatic cell (体细胞) would destroy the individual. Maintenance of the correctness of the DNA sequence is definitely crucial for living organisms
Two important sources for mutation (unavoidable) ■ Inaccuracy in DNA replication-Errors (错误) ■( Chemical and radiant damage to the genetic material (environment)
