Explanation / Answer
Which of the following are not required for PCR?
b. Restriction enzymes
Taq polymerase is responsible for polymerization of the strand; to begin PCR there should be the gene sequence to be copied.
PCR can be used to:
a. Identify human tissue at a disaster site
Since the amount of DNA available at the disaster site can be very less, so PCR is used to amplify the DNA which is later used for identification of the victims.
Transgenic organisms:
c. Contain DNA from other sources
These organisms are modified using genes from other source having beneficial qualities.
To investigate crime scenes scientists will often use DNA as evidence. After the DNA is isolated a DNA fingerprint can be made to determine the presence of a suspect at the crime scene. Which of the following can be used to make a DNA fingerprint?
c. Gel electrophoresis?
Gel electrophoresis is a part of DNA fingerprinting.
