Solution

It seems like you forgot to mention the name of the substance in your question. However, based on the context, I believe you're referring to Melanin. Melanin is produced in specialized skin cells called melanocytes. It absorbs ultraviolet radiation from sunlight, preventing it from causing mutations in the DNA of skin cells. Here are the steps:

  1. The process begins in the skin where there are specialized skin cells known as melanocytes.
  2. These melanocytes produce the pigment melanin when the skin is exposed to sunlight.
  3. The melanin is then distributed to the outer layers of the skin cells.
  4. When ultraviolet radiation from sunlight hits the skin, the melanin absorbs it.
  5. By absorbing the ultraviolet radiation, melanin prevents it from reaching the DNA of skin cells.
  6. This is crucial because if the ultraviolet radiation was to reach the DNA, it could cause mutations which could lead to skin cancer.

he main function of melanin pigment is to protect the of keratinocytes from UV radiation.

In many humans, exposing the skin to sunlight over prolonged periods of time results in the production of more pigment by the skin cells (tanning). This change in skin color provides evidence that (1) ultraviolet light can cause mutations (2) gene action can be influenced by the environment (3) the inheritance of skin color is an acquired characteristic (4) albinism is a recessive characteristic
