PPT-Crossovers and Mutation

Richard P Simpson Genotype vs Phenotype The genotype of a chromosome is just the basic data structure it bits in a binary chromosome The Phenotype is the object that the chromosome represents. Jesus.

A . frameshift. mutation – . a point mutation due to an addition . or deletion of a DNA base that causes a major change in the genetic code.. Mutation refers to sudden heritable change in the phenotype of an individual. In the molecular term, mutation is defined as the permanent and relatively rare change in the number or sequence of nucleotides. In other words, mutations arise due to change in DNA bases. The change in the nucleotide may involve replacement of one . Is a natural process that changes a DNA sequence.. Mutant or Mutation – to describe something undesirable or broken.. Rarely cause death or disease. Generates new variations that can give an individual a survival advantage.. Is a natural process that changes a DNA sequence.. As a cell copies its DNA before dividing, a “typo” occurs every 100,000 or so nucleotides.. That’s about 120,000 typos each time one of our cells divides.. Mutation may result in coding sequences for new amino acids in proteins or not!. Mutations can occur due to errors during DNA replication (. replication-dependent. mutations). Mutations can also occur independently of DNA replication (.
