It is easy to say that tanning has become a popular activity that most people do whether it is at the beach or on a tanning bed. Everyday we are exposed to sunlight whether we are walking to the park or just walking to class or work. Even though UV light is not visible, we are still exposed to it when we go on tanning beds or get sunburn. What exactly is this doing to our body?

UV light comes from sunlight and can emit a florescence with black lights. UV radiation causes damage in our DNA, skin cancer, and sunburn. When UV radiation hits our DNA it causes a strand from our DNA to break. UV light also causes thymine base pairs to pair with each other into thymine dimers. This improper base pair leads to a frameshift mutation.

The thymine dimers can be fixed with base excision repair, but if it is not fixed it can cause the DNA to be degraded. When the thymine bases bind to each other it creates a photodimer. To fix the photodimer, the enzyme CPD photolyase binds to it and splits the thymine bases to repair it correctly.

The direct damage of DNA triggers the body to produce melanin as a defense. By turning the UV heat into harmless heat, melanin protects the body from DNA damage. If the repair mechanisms are not able to repair this break, mutations will occur. If enough mutations accumulate it can lead to skin cancer or other skin diseases.

Although UV radiation is usually seen as a negative issue, it can also be beneficial in some cases. UV radiation increases the production of vitamin D, which can have positive health effects in calcium metabolism, immunity, cell proliferation, insulin secretion and blood pressure. When there is not enough UV radiation it could lead to a shortage in vitamin D.

When people are over exposed to UV radiation, it will lead to sun burn and skin cancer. This can lead to damage in the skin, eyes, and immune system. The most dangerous form is malignant melanoma which is a skin cancer caused by indirect DNA damage.

Ways to prevent UV radiation is to put on sunblock and sunscreen when doing activities that will include a lot of sunlight exposure. It is best to limit the amount of UV radiation that is exposed to your skin by decreasing the amount of artificial tanning in tanning beds. Sunscreen prevents sunburn by protecting direct DNA damage. It is also important to protect the eyes by wearing sunglasses. By decreasing the amount of exposure to UV radiation we are protecting our bodies against skin cancer.

Thymine Dimers
DNA is composed of four different bases: adenine, gaunine, cytosine, and thymine. These bases are complimentary to eachother, meaning that adenine only pairs with thymine and guanine pairs only with cytosine. Adenine and guanine are both purines and cytosine and thymine are pyrimidines, therefore purines pair with pyrimidines and vice…
