- Nullisomy is a genome mutation where a pair of homologous chromosomes that would normally be present is ______.Statement 1: Embryonic stem cells are pluripotent which means that they are capable of differentiating into many different cell types. Statement 2: Adult stem cells are cells that generate a limited number of cell types. O Both statements are true. Both statements are false. Statement 1 is true. Statement 2 is false. O Statement 1 is false. Statement 2 is true.In a type of skin cancer known as melanoma, skin cells divide uncontrollably. This out-of-control division can be deadly, but a lackof cell division could be harmful as well. Describe why and whenskin cells do need to replicate.
