Unit 1 Mutation Flashcards
Deletion of genes
Chromosome mutation in which a sequence of genes is lost from a chromosome
Deletion of nucleotide
Single gene mutation involving removal of a nucleotide from a sequence
Duplication
Chromosome mutation in which a sequence of genes is repeated on a chromosome
Genome
Total genetic material present in an organism
Insertion
Single gene mutation in which an additional nucleotide is placed into a sequence
Inversion
Chromosome mutation in which a set of genes rotates through 180?
Mutations
Random changes to DNA sequences
Non-coding sequence
DNA sequence that does not code for protein, it is transcribed but not translated.
Polyploidy
Possession of extra set(s) of chromosomes
Splice-site mutation
Mutation at a point where coding and non-coding regions meet ina section of DNA
Substitution
Single gene mutation in which one nucleotide is replaced by another
Translocation
Mutation in which part of a chromosome becomes attached to another
Chromosome mutation in which a sequence of genes is lost from a chromosome
Deletion of genes
Single gene mutation involving removal of a nucleotide from a sequence
Deletion of nucleotide
Chromosome mutation in which a sequence of genes is repeated on a chromosome
