PT #061 DNA Profiling Process

Which type of polymorphisms involve DNA sequences that range in length for 9 to 80 Baes

• STR

• VNTR

• PCR

• VWR

DNA restriction enzymes

• are used to repair DNA

• are involved in DNA synthesis

• restrict DNA from being amplified

• cut DNA into fragments of different lengths

Which technique is used to amplify DNA for analysis

• PCR

• STR

• KTM

• RNA

What is the purpose of PCR?

• To produce millions of copies of DNA.
• To produce millions of copies of a specific region of DNA
• To add nucleotides to a DNA sequence
• To watch polymerase work.

Explain the use of PCR in forensic science and its significance.

• PCR is used to amplify small amounts of DNA for analysis in forensic science.

• PCR is used to create new DNA samples for forensic analysis.

• PCR is used to identify the age of the DNA sample in forensic science.

• PCR is used to extract DNA from the crime scene in forensic science.

What is the function of a primer?

• To identify the particular region of DNA to be copied by PCR.

• To copy DNA.

• To create DNA nucleotides.

• To maintain the temperature of the PCR reaction.
