Explanation:
Cancer mutations affect cell cycle regulators.
Cell cycle is a highly regulated process by the regulators that can promote cell cycle or inhibit the cycle. Genes that encode for those regulators are classified into two groups:
- proto-oncogenes-encode for positive regulators such as growth factor receptor. If a cancer mutation occurs in the proto-oncogene it becomes oncogene and its product is overactivated. The increased avtivity of positive regulators leads to abnormal cell division.
- tumor suppresor-the products of such genes blocks the cell cycle, but after the mutation they become inactive, which leads to uncontrolled cell cycle.
Answer:
It really depends on the location. If its underneath the earth and the magma will take a while to cool but if on surface, it should cool in a matter of days to weeks. In this situation yes because its going in the air and is gonna land on the ground which will cool pretty quickly.
