Two things that can cause cancer include 1) death and miscopying 2) exact copy of heathly dna and damaging effect of radiation 3) mutations and death 4) miscopying and damaging effects of radiation

Mutations and Death is the right answer

b c a d mark me

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
