Mutations

Which of these can cause mutations?

• cell division errors

• chromosome mutations errors

• mutagens

• hypothermia

Which of the following are types of gene mutations?

• insertion

• deletion

• substitution

• nondisjunction

This type of mutation results in the removal of one or more nucleotides in a gene.

• deletion

• insertion

• substitution

• frameshift

This type of mutation results in the addition of one or more nucleotides in a gene.

• deletion

• insertion

• substitution

• frameshift

This type of mutation results in the switch of one or more nucleotides into (a) different nucleotide(s) in a gene.

• deletion

• insertion

• substitution

• frameshift

This type of mutation results in the full sequence after the mutation changing, causing a completely different set of amino acids to be produced.

• deletion

• insertion

• substitution

• frameshift

This type of mutation results in the removal of all or part of a chromosome.

• deletion

• inversion

• translocation

• nondisjunction

• addition

This type of mutation results in part of the chromosome being attached in reverse order/the other way around.

• deletion

• inversion

• translocation

• nondisjunction

• addition

This type of mutation results in part of one chromosome reattaching to a different chromosome (e.g. part of chromosome 2 attaches to chromosome 6)

• deletion

• inversion

• translocation

• nondisjunction

• addition

This type of mutation results in there being part of all of an additional or missing copy of a chromosome.

• deletion

• inversion

• translocation

• nondisjunction

• addition
