• transformation

• conjugation

• pathogenic

• non-pathogenic

• mouse.

• bacterium

• person

Avery, et al. proved that DNA is the genetic material. They also tested which other molecule(s) from pathogenic bacteria in their experiment? (choose all that apply.)

• RNA

• protein

• phospholipids

• cholesterol

• water

Cells that can take up DNA from the environment are called ________ cells. This process typically involves the additional of chemicals and heat.

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 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.

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.
