What makes it possible for sunlight to change genetic material?

When light hits CRY2, it changes shape and binds to its natural partner protein, known as CIB1. ... When light shines on the cells, the CRY2 protein binds to CIB1, which is floating in the cell. CIB1 brings along a gene activator, which initiates transcription, or the copying of DNA into mRNA. The melanin-assisted process creates lesions known as cyclobutane pyrimidine dimers in DNA, which can lead to mutations that cause melanoma, a type of skin cancer. These lesions are identical to the well-known genetic alterations caused when UV light directly strikes DNA

Explanation:

thats ur answer cuz ive done research on it b4

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
