7.1 DNA structure and replication: Tandem Repeats

Understanding that:

- DNA structure and replication allows for DNA profiling to occur
- Tandem repeats are what is used in DNA profiling
- No two people have the same exact tandem repeats
- Some regions of DNA do not code for preens but have other important functions such as DNA profiling
-Tandem repeats can be seen in Gel electrophoresis (PCR)
