Term | Definition |
DNA | a long linear polymer found in the nucleus of a cell and formed from nucleotides and shaped like a double helix |
Genetic change | happens spontaniously when the DNA is reproducing itself but can also be because of radio activity, sun light, chemicals a virus or in a laboratory. |
Chromosome | DNA-containing structure that carries genetic material from one generation to another. |
Mutation | permanent change in a cell's DNA, ranging from changes in a single base pair to deletions of large sections of chromosomes. |
Base sequence | The order of nucleotide bases in a DNA molecule. Length is usually defined as the number of base pairs. |
Substitution mutation | a type of mutation where one base pair is replaced by a different base pair. The term also refers to the replacement of one amino acid in a protein with a different amino acid. |
Insertion mutation | is the addition of one or more nucleotide base pairs into a DNA sequence. This can often happen in microsatellite regions due to the DNA polymerase slipping. |
Deletion mutation | is a mutation (a genetic aberration) in which a part of a chromosome or a sequence of DNA is lost during DNA replication. |
Frameshift mutation | is a genetic mutation caused by indels (insertions or deletions) of a number of nucleotides in a DNA sequence that is not divisible by three. |
Codon | three-base code in DNA or RNA. |
DNA triplet | three consecutive nitrogenous bases in the code of DNA |
Gamete | a haploid sex cell, formed during meiosis that can combine with another haploid sex cell and produce a diploid fertilized egg. |
