In Cells That Are Exposed to Sunlight, Ultraviolet (UV) Light

question 31

Short Answer

In cells that are exposed to sunlight, ultraviolet (UV) light can result in covalent linkage between two adjacent DNA bases. If not repaired in time, such dimers can lead to inheritable mutations. Consider the sequence 5?-GGTATGATCATTATAA-3? in the chromosome of a cell that is exposed to intense sunlight. How many possible dimers can form in the region of DNA double helix corresponding to this sequence?
