<span>UV has high frequency and hence it has high energy.
It can cause mutations in our DNA. It can change the DNA shape and also the

is skin cancers. Other than cancers, UV rays can cause premature aging of skin,
eye damage, skin burning and suppression of the immunity.</span></span>

Answer:
The scheme of the tautomers of cytosine, guanine and thymine are found in the attached file
Explanation:
The primary imine-amine tautomerism occurs in heterocyclic compounds where hydrogen may be forming the amino group (primary amine form) or migrate to adjacent nitrogen (imine form), may occur in some nitrogenous bases such as cytosine. Thymine shows double lactam-lactymal tautomy (where hydrogen migrates from the nitrogen atom to the oxygen atom of the heterocycle oxo group (lactam form) and vice versa (lactose form)), and guanine and cytosine can both.
