Higher Biology Unit 1 Key Area 6 Match Terms

a section of a chromosome is added from its homologous partner

• substitution

• insertion

• duplication

• translocation

substitution that results in some introns being retained and/or some exons not being included in the mature transcript

• substitution

• missense

• nonsense

• splice-site

causes all of the codons and all of the amino acids after the mutation to be changed. this has a major effect on the structure of the protein produced

• frame-shift mutation

• chromosome structure mutation

• single gene mutation

• inversion

a section of chromosome is reversed

• translocation

• substitution

• deletion

• inversion

substitution that results in one amino acid being changed for another. this may result in a non-functional protein or have little effect on the protein.

• nonsense

• missense

• deletion

• insertion

base replaced by another, with no other bases changing

• mutation

• insertion

• substitution

• missense

base deleted from the sequence/gene removed from chromosomes

• nonsense

• chromosome structure mutation

• translocation

• deletion

a section of a chromosome is added from its homologous partner

• single gene mutation

• inversion

• translocation

• duplication

changes in the genome that can result in no protein or an altered protein being expressed

• nonsense

• deletion

• mutation

• dulpication

additional base inserted into the sequence

• insertion

• nonsense

• duplication

• translocation
