DNA sequencing Essay
1 How can scientists identify specific bacteria when they are amplifying and studying the same region of DNA in each species? Specialist or doctors compare the nucleotides of the DNA sequences to specific bacteria.
2 Why is PCR used in the process of DNA sequencing?
Used to make small segments of DNA. To analyze DNA more DNA is required to attain proper results.
3 How can the DNA sequencing technique shown in the virtual lab be used to identify other classes of pathogens, such as viruses? The same process can be performed by entering parts of the sequences into the database.
4 Explain how sequence data and information about patient symptoms led you to diagnose Sue’s illness. My partner and I looked up different diseases that could be causing Sue’s symptoms until we came across 3 strong matches. Then the disease database testing identified which disease it was.
5 How can DNA sequencing be used to identify genetic risk for certain diseases and disorders?
