Look at the following gel to the left. From the evidence DNA, which individual matches the DNA evidence left at the crime scene?

The table shows the presence/absence and size of DNA bands of known samples using gel electrophoresis. Explain conclusions you can draw from the data in the table.

Consider the four extraction/purification methods . a. Which extraction method would you use for a touch DNA sample? Explain your reasoning.b. Which extraction method would you use for a sample containing a mixture of primarily non-human and some human DNA? INFO: the 4 extraction methods are QIAamp manual extraction, QIAcube semi-automated extraction, DNA IQ extraction, or FTA punch purification

Many times a forensic scientist has only a single hair or a single drop of blood for analysis. The amount of DNA in this kind of material is very tiny, and is not enough to use for comparison. In other words, running a single experiment to compare the DNA in a drop of blood with several suspects would use up all of the DNA in that drop of blood. This could be a serious problem if none of the suspects provided a match. How would a forensic scientist increase the amount of DNA available to them, starting with the DNA that would be found in their crime scene sample, such as a drop of blood from a suspect?
