DNA QUANTITATION If you have the extracted/purified DNA and will not be immediately loaded in the spectrophotomer, how can you maximize the storage life of DNA? What practices will maximize the quality of your DNA sample?
Gel Electrophoresis Background and Protocol: Gel electrophoresis is a laboratory technique that separates molecules by size using an electric current. The test has a positive and negative side. Do you believe DNA should be loaded on the positive (red) side or the negative (black) side? Please explain why using scientific reasoning. Will larger DNA bands be closer or farther away from the well where you administered samples? Why?
DNA extraction, PCR, gel electrophoresis, and DNA sequencing of PCR products. Give a description of these methods and the materials required to perform each of these molecular techniques
DNA Profiles as Tools for Identification A PCR-based paternity test is conducted using STRs that consistently produce a unique DNA fragment pattern from a single chromosome. Examining the results of the following Southern blot, which male(s) can be excluded as the father of the child? Which male(s) could be the father of the child?
Recall what you know about the rules of gel electrophoresis and the migration of DNA on an electrophoresis gel. The PV92 PCR products could be 941bp or 641bp long. We are calling the longer allele that has the Alu insert the "+" allele and the shorter allele that doesn't have the insert the "-" allele. Which fragment will run faster on the electrophoresis gel, the 941bp or the 641bp allele? 941 641
DNA QUANTITATION Explain the rationale behind using the A260/A280 in the spectrophotometric measurements of DNA.
What other online tools are available for nucleic acid sequence analysis? What can they be used for? How do they differ from BLAST and BLAT? Please provide links to the tools that you find.

DNA Extraction Using household materials Wash the fruit. Place the fruit (e.g. banana) in a zip lock plastic bag and crush it with your fist. Add the one half teaspoon of salt and one tablespoon of dishwashing liquid to the mashed fruit mixture in the bag, zip it up and squeeze it in your hands for 1 minute. Place the strainer over the small glass. Pour the mixture into the strainer. Filter the mixture into the glass. Slowly pour ice cold rubbing alcohol into the glass, until it is about half full. Let it stand until the alcohol will form a separate layer on top of the fruit filtrate. Keep the glass still at eye level; do not shake it. Watch what happens. DNA will begin to a.What is the importance of centrifugation in step 3? b.
