Mutation Flashcards
2 types of mutation?
Gene/ point mutation
Chromosome mutation
What is gene mutation
Alterance is based sequence at the level of a singular or a few base pairs on the DNA
Chromosome mutation?
Alterance of the number of chromosomes or gross structure of chromosomes
What affect does substituting a single base pair have
Can cause the codon to code for a different amino acid
Does substituting a base always have an affect on the protein produced
No, bc of redundancy/ the idea of a degenerate code
What affect does base pair addition or deletion have
Shifts the sequence out of frame resulting in multiple amino acid changes
What do we call the change caused by base pair addition or deletion
frameshuft mutations
3 types of gene mutation
base pair addition, mutation and substitution
Base pair substitution?
Single base pair change that alters a single amino acid or none in the new codon codes for the same amino acid as the original
Base pair deletion
Removal of any number of base pairs affecting all following amino acids
Base pair addition
Addition of any number of base pairs affecting all following amino acids
