Problems that occur with dna replication bbc
WebbErrors in DNA replication can result in the mutations like the permanent mutation. In the DNA repair mechanism, the repair enzymes find the mistakes that occur and removes them. Subsequently, they recruit the right nucleotide in place. But some replication errors pass these processes and mutations occur. WebbDescribe mechanisms of DNA repair. When a cell divides, it is important that each daughter cell receives an identical copy of the DNA. This is accomplished by the process of DNA …
