This technique used to analyze DNA involves the

• synthesis of new DNA strands from subunits

• separation of DNA fragments based on size

• production of genetically engineered DNA molecules

• removal of defective genes from DNA

DNA fingerprinting works because

• Most genes are dominant

• All organisms contain RNA

• The most important genes are different among most people

• No two people, except identical twins, have exactly the same DNA 

In gel electrophoresis, the largest DNA fragment will appear

• closest to the starting wells

• farthest from the starting wells

• three quarters away from the starting wells

• it depends on how many fragments there are

Which is the primary purpose of using restriction enzymes in gel electrophoresis?

• It allows the strands of DNA to be cut into various lengths for testing

• It restricts the number of base pairs that can be tested in a sample

• It makes the testing simpler by moving the strands into the gel faster

• It charges the DNA strands

This equipment is used to 

• measure & transfer large volumes

• measure & transfer small volumes

• spin chemicals/tubes

• sterilize equipment

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.

• Parents C and D

• Parents E and F

• Parents A and B

• Parents G and H
