1By observing bacterial transformation, Avery and other scientists discovered that the nucleic acid DNA stores and transmits genetic information from one generation of bacteria to the next.
- ATrue
- BFalse
2Hershey and Chase's experiment with bacteriophages confirmed Avery's results, convincing many scientists that DNA was the genetic material found in genes-not just in viruses and bacteria, but in all living cells.
- ATrue
- BFalse
3The DNA that makes up genes must be capable of storing, copying, and transforming the genetic information in a cell.
- ATrue
- BFalse
4DNA is a nucleic acid made up of amino acids joined into long strands or chains by covalent bonds
- ATrue
- BFalse
5The clues in Franklin's X-ray pattern enabled Watson and Crick to build a model that explained the specific structure and properties of DNA.
- ATrue
- BFalse
6The double-helix model explains Chargaff's rule of base pairing and how the two strands of DNA are held together.
- ATrue
- BFalse
7DNA poly merase is an enzyme that joins individual nucleotides to produce a new strand of DNA.
- ATrue
- BFalse
8Replication in most prokaryotic cells starts from a single point and proceeds in two directions until the entire chromosome is copied.
- ATrue
- BFalse
9In prokaryotic cells, replication may begin at dozens or even hundreds of places on the DNA molecule, proceeding in both directions until each chromosome is completely copied.
- ATrue
- BFalse
10The process by which one strain of bacterium is changed into another strain is called
- Atranscription
- Btransformation
- Cduplication
- Dreplication

- Atolerate high temperatures.
- Bcarry and make copies of information.

16The bonds that hold the two strands of DNA together come from
- Athe attraction of phosphate groups for each other.
- Bstrong bonds between nitrogenous bases and the sugar-phosphate backbone.
- Cweak hydrogen bonds between nitrogenous bases.
