Ultraviolet (UV) photons harm the DNA molecules of living organisms in different ways. In one common damage event, adjacent bases bond with each other, instead of across the “ladder.” This makes a bulge, and the distorted DNA molecule does not function properly.
Explanation:
The process of copying genetic info stored in DNA to mRNA is Transcription
The link between<span> oxygen and cancer</span> is clear. In fact, an underlying cause of cancer is usually low cellular oxygenation levels.
In newly formed cells, low levels of oxygen damage respiration enzymes so that the cells cannot produce energy using oxygen. These cells can then turn cancerous because they don't make enough energy to function normally in the body.
by protecting surviving rainforests means more oxygen available
