During PCR, what happens during the Denaturation step?
DNA strands are separated according to size using gel electrophoresis.
Primers form base pairs with the single-stranded template DNA.
DNA polymerase adds new nucleotides to the primer to elongate the new strand.
Hydrogen bonds between bases are broken using high heat to separate DNA strands.
Which of the following statements are true about DNA structure?
The DNA backbone ("sides of the ladder") is made up of sugars and phosphates.
The sugars and phosphates make up the unique code of each gene.
The DNA backbone is the same for every person.
Bases and sugars pair together to form the "rungs" of the DNA ladder.
The sequence of bases is unique for each person.
During which PCR step do primers form complementary base pairs with single-stranded template DNA?
Denaturation
Annealing
Extension
Synthesis
Which part of Sanger (Cycle) Sequencing is NOT found in regular Polymerase Chain Reaction (PCR)?
DNA polymerase
Primers
Deoxyribonucleotides (dNTPs)
Dideoxyribonucleotides (ddNTPs)
DNA template
How are deoxyribonucleotides different from dideoxyribonucleotides? Choose all that apply.
Deoxyribonucleotides are used in both PCR and Cycle Sequencing.
Dideoxyribonucleotides are missing an OH group compared to deoxyribonucleotides.
You cannot add new nucleotides to a deoxyribonucleotide.
Deoxyribonucleotides are NOT found in natural living cells.
Dideoxyribonucleotides are labeled with fluorescent tags.
