The saying that DNA is like a blueprint of your body is misleading. The DNA does not specify what structures your body contains or how those structures are related to each other in space. A better analogy might be that the DNA is like a computer’s program.

by Rich Feldenberg Welcome back to your mutation station. Today we’ll look at a harmful effect on your DNA due to ultraviolet light, which leads to dimerization of the nucleotide bases thymine (T). If there are two T bases next to each other in the DNA strand and they absorb UV light they can undergo a photochemical reaction that causes them to link-up. The double bonds in the base break and then form single bonds to their neighbor. This blocks normal base pairing on to the other DNA strand of the double helix, and results in a mutation. Fortunately there are cellular repair mechanisms that can find and fix these errors, but some errors escape detection and cause major harm. Some melanomas are thought to be due to thyimine dimers caused by the effect of UV sunlight. Thymine dimers are actually a more specific form of what is called pyrimidine dimers. The bases thymine and cytosine (T and C)
