Homework Answers
Excess exposure to ultraviolet light can cause DNA damage because of production of methylated thymidine.
DNA damage from UV lights causes cross-linking between adjacent cytosine and thymine bases creating dimers or any pyrimidine dimers. This causes a kink in the DNA that keeps it from proper mRNA transcription or DNA replication.

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? 04 O3 Sort the following steps in the order that they normally happen during the...

How is this possible? 1 points Question 7 Scientists James Watson and Francis Crick determined the double helix structure of DNA. Why is that structure important in DNA replication? A. When the DNA separates into two halves during replication, each half is a mirror image of the other, so the new halves fit right back together again in the new cell. B. The structure...
