Cancer is formed when there are mutations in a number of genes.
Explanation:
Malignant tumors are gene diseases which do not mean that cancer is necessarily an inherited disease (only in 5-10% of cases the cancer is inherited) because the vast majority of other tumors are the result of somatic, ie secondary, mutations that lead to malignant transformation.
Only 2% of human diseases are monogenic (caused by a change in one gene). The remaining 98% of the disease is either polygenic (caused by a change in several genes at the same time) or epigenetic (caused by non-genetic or post-genetic disorders of cellular molecules).
I'm pretty sure that Nucleotides are found in DNA and RNA.

When charged particles from the sun strike atoms in earth's atmosphere, it causes electrons to move to a higher energy state. When the electrons drop back to a low energy state they release light photons. This is what causes the Aurora lights
