DNA Mutation - an overview ScienceDirect Topics

WebDNA replicates by a semi-conservative method in which each of the two parental DNA strands act as a template for new DNA to be synthesized. After replication, each DNA has one parental or “old” strand, and one daughter or “new” strand. Errors made during replication are typically repaired. If they are not, mutations can result. WebDNA damage is often detrimental; DNA damage worsens protein activity and negatively affects phenotype.
