Concept explainers
Interpretation:
Describe the effect on the protein produced if the DNA coding sequence “-CAA-CCG-GAT-“were miscopied as “-CGA-CCG-GAT-�.
Concept introduction:
A mutation is a shift in a brief area of a genome's
Mutations are caused either by
All cells have DNA-repair enzymes, which try to minimize the amount of mutations occurring. There are two ways these enzymes work, some are pre-replicative, searching for DNA for nucleotides with uncommon structures, replacing them before replication happens; others are post-replicative, checking for mistakes for freshly synthesized DNA, correcting any mistakes, they discover. Therefore, a possible mutation definition is a deficiency in DNA repair.
