Cadherin Proteins Help Animal Cells Stick (Adhere) to Each Other

Cadherin proteins help animal cells stick (adhere) to each other. Choose which statement about cadherin in cancer cells that are metastasising (spreading) throughout a patient's body is most likely correct.

A) Cadherin proteins in metastasising cancer cells are likely to have mutations that make them less "sticky".
B) Cadherin proteins in metastasising cancer cells are likely to have mutations that make them more "sticky".
C) Mutations in cadherin proteins are unlikely to affect the metastasising of cancer cells.
D) Mutations in cadherin proteins accumulate at a constant rate that can be measured by a molecular clock.
