Question

mutation within a gene

gene duplication

mutation in a regulatory region of a gene

exon shuffling

horizontal gene transfer

Match the type of phenotypic change below with the type of genetic change most likely to cause it. Each type of genetic change may be used more than once, or may not be used at all A protein acquires a DNA-binding domain. A protein becomes much more unstable. A protein normallyed expressed only in the liver is now expressed in brain tissue. A protein that normally localizes in the nucleus is now localized in the cytoplasm. Tandem copies of a gene are found in the genome. A copy of a bacterial gene is found integrated on your chromosome 14

Explanation / Answer

A protein acquires a DNA-binding domain. – gene duplication

A protein becomes much more unstable. – mutation in the regulatory region of a gene

A protein normallyed expressed only in the liver is now expressed in brain tissue. exon shuffling

A protein that normally localizes in the nucleus is now localized in the cytoplasm. - exon shuffling

Tandem copies of a gene are found in the genome. – gene duplication

A copy of a bacterial gene is found integrated on your chromosome 14 – horizontal gene transfer
