What needs to be done before PCH can be performed - Answer DNA has to be isolated from the Cells How did you collect liquid in a lab - Answer Using a pipette What do you need to do each time before using a pipette to collect liquid - Answer Put on a new sterile pipette tip What is the fiction of primers in a PCR reaction? - Answer Bind to specific sites on the DNA Wh is it important to change the pipette tip? - Answer To avoid cross contamination For which enzyme ar...

What needs to be done to the sample of blood before PCR? - Answer DNA must be isolated from the cells. How did you collect quids in the lab? - Answer A pipette What do you need to do each time before using a pipette to collect liquid? - Answer Put on a new, sterile pipette tip. What is the function of primers in a PCR reaction? - Answer Bind specific sites on DNA Great that you throw away the used pipette tip, why is it important to change the pipette tip? - Answer to ...

The Bradford assay only works at low protein concentrations (from 0.05 to 0.5 mg/mL protein) How can we reduce the concentration of protein in our sample? - Answer dilute the sample what is the volume range of the P1000 - Answer 200 uL - 1000 uL how would you set the volume to pipette 20 uL with the P20? - Answer "200" how much protein do you need to add to the 800 uL buffer in the first microcentrifuge tube to make a 1:5 dilution? - Answer 200 uL how much fluid from th...

Describe the purpose of PCR - Answer Polymerase chain reaction is a technique used to target specific fragments of DNA and artificially amplify (increase their quantity) them. Explain the use of primers in PCR - Answer The primer is an artificial strand of DNA that is made with a complimentary base sequence to the beginning of the DNA fragment to be amplified. It is used to locate the specific DNA target sequence to be copied Describe the process of PCR - Answer 1. The DNA fragmen...
