H2SO4Which of the following gels is the preferred choice for separation of DNA fragments? Agarose Polyacrylamide SDS PAGE (sodium dodecyl sulphate polyacrylamide gel electrophoresis) AgarThe concentration of a DNA sample is 40 nano grams per milliliter how many nanoliters will be needed to obtain 0.5 nano grams of DNA
- Which technique used to manipulate genetic material results in a significant increase in DNA or RNA fragments? Group of answer choices heat shock treatment electroporation gel electrophoresis polymerase chain reactionDNA EXTRACTION Materials: knife 1 cup of fruit Table salt clean piece of cloth or strainer for filtering resealable bag dishwashing liquid 70% rubbing alcohol (chilled) shot glass (or any transparent and narrow container resembling a test tube) How to do the extraction: Before you begin, make sure you have chilled your alcohol in the freezer for at least 3 hours. Room temperature alcohol will not work nearly as well as cold alcohol. Place about 50 mL of alcohol in the freezer to chill it and take it out only when you’re going to need it. (The alcohol will not actually freeze.) 1. The first thing you will need is a sample. Since DNA is found in all living…Examine your stained gel on a transilluminator depending upon the stain you used. Your instructor may instead have you photograph the gel and perform your analysis using the photograph. Use the DNA ladder in lane 5 to calculate band sizes.

The final volume will be 20 ?μl. How much of each of the following reagents will you use to obtain the indicated working concentrations? 10x restriction buffer >> working concentration 1x 1 mg/mL bovine serum albumin (BSA) >> working concentration 100?μg/mL
- Gel Electrophoresis is used often in forensics. Look at the following gel to the left. From the evidence DNA, which individual matches the DNA evidence left at the crime scene?Laemmli polyacrylamide gel electrophoresis (SDS-PAGE). The essence of the method. The role of SDS in this type of electrophoresis. The role of the concentrating and separating gels, which is the reason for the different pH of these gels.This piece of DNA is cut by EcoRI, the resulting fragments are separated by gel electrophoresis, and the gel is stained with ethidium bromide. Draw a picture of the bands that will appear on the gel.
