Molecular and Cell Biology Chapter 16

The process of making a copy of DNA

• antiparallel
• DNA replication
• double helix
• origin of replication

The transfer of genetic material in the form of DNA fragments from one cell to another or from one organism to another

• bacteriophage
• helicase
• transformation
• virus

Ultramicroscopic infectious agent that replicates itself only within cells of living hosts

• bacteriophage
• helicase
• topoisomerase
• virus

a virus that infects bacteria

• bacteriophage
• H1N1
• antiparallel
• virus

Two strands of nucleotides wound about each other; structure of DNA

• Circular
• Double helix
• Linear
• Single stranded

The opposite arrangement of the sugar-phosphate backbones in a DNA double helix.

• antiparallel
• double helix
• origin of replication
• semiconservative

Site where the replication of a DNA molecule begins, consisting of a specific sequence of nucleotides.

• antiparallel
• helicase
• origin of replication
• single strand binding proteins

Method of replication that implies that each new strand of DNA is half original and half new

• Conservative
• Dispersive
• Semiconservative

A Y-shaped region on a replicating DNA molecule where new strands are growing.

• Antiparallel
• helicase
• replication fork
• topoisomerase

Proteins that bind to and stabilize he single strands of DNA exposed when helicase unwinds the double helix in preparation for replication.

• helicase
• primer
• single strand binding proteins
• topoisomerase
