Structure of DNA

Using the South University Online Library or the Internet, research DNA sequencing.

Based on your research, complete the following discussions:

  • DNA sequencing has become a valuable tool in many areas of science, including forensic medicine and biological research. In relation to this, answer the following questions.
    • Describe the steps by which DNA sequencing is performed.
    • Describe, using at least one example, of how DNA sequencing has become a valuable tool in forensic medicine and/or biological research.
  • What are the steps involved and the enzymes used in DNA replication? In your opinion, can a disorder result from the malfunction of any enzyme used during DNA replication? If yes, identify any one disorder and explain how it is caused. If no, why?
  • Since one transcription factor can control multiple genes, mutations in transcription factors can have long-reaching effects.
    • Can a disease result from a mutation in a transcription factor? If so, provide at least one example, naming the transcription factor, the mutation, and the congenital defect that arises.
