Question 1 of 23

1

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.

Select one of the following:

  • True
  • False

Explanation

Question 2 of 23

1

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.

Select one of the following:

  • True
  • False

Explanation

Question 3 of 23

1

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

Select one of the following:

  • True
  • False

Explanation

Question 4 of 23

1

DNA is a nucleic acid made up of amino acids joined into long strands or chains by covalent bonds

Select one of the following:

  • True
  • False

Explanation

Question 5 of 23

1

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.

Select one of the following:

  • True
  • False

Explanation

Question 6 of 23

1

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

Select one of the following:

  • True
  • False

Explanation

Question 7 of 23

1

DNA poly merase is an enzyme that joins individual nucleotides to produce a new strand of DNA.

Select one of the following:

  • True
  • False

Explanation

Question 8 of 23

1

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

Select one of the following:

  • True
  • False

Explanation

Question 9 of 23

1

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.

Select one of the following:

  • True
  • False

Explanation
