Question 1

Question
By 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.
Answer
  • True
  • False

Question 2

Question
Hershey 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.
Answer
  • True
  • False

Question 3

Question
The DNA that makes up genes must be capable of storing, copying, and transforming the genetic information in a cell.
Answer
  • True
  • False

Question 4

Question
DNA is a nucleic acid made up of amino acids joined into long strands or chains by covalent bonds
Answer
  • True
  • False

Question 5

Question
The clues in Franklin's X-ray pattern enabled Watson and Crick to build a model that explained the specific structure and properties of DNA.
Answer
  • True
  • False

Question 6

Question
The double-helix model explains Chargaff's rule of base pairing and how the two strands of DNA are held together.
Answer
  • True
  • False

Question 7

Question
DNA poly merase is an enzyme that joins individual nucleotides to produce a new strand of DNA.
Answer
  • True
  • False

Question 8

Question
Replication in most prokaryotic cells starts from a single point and proceeds in two directions until the entire chromosome is copied.
Answer
  • True
  • False

Question 9

Question
In 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.
Answer
  • True
  • False

Question 10

Question
The process by which one strain of bacterium is changed into another strain is called
Answer
  • transcription
  • transformation
  • duplication
  • replication

Question 13

Question
Before DNA could definitively be shown to be the genetic material in cells, scientists had to show that it could

Question 14

Question
A nucleotide does NOT contain

  • A=T=C=G

Question 16

Question
The bonds that hold the two strands of DNA together come from
Answer
  • the attraction of phosphate groups for each other.
  • strong bonds between nitrogenous bases and the sugar-phosphate backbone.
  • weak hydrogen bonds between nitrogenous bases.
  • carbon-to-barbon bonds in the sugar portion of the nucleotides.
