DNA and The Cell Cycle

Which of the following things does a nucleotide NOT contain?

• a sugar
• a nitrogen base
• a phosphate
• a polymerase

The DNA is found in the nucleus of what type of organisms?

• Bacteria
• Eukaryotes
• Prokaryotes
• Viruses

Which of the following is a base that is NOT contained in DNA?

• Adenine
• Thymine
• Uracil
• Guanine

Which of the following does NOT describe the structure of DNA?

• double helix
• nucleotide polymer
• sugar-phosphate backbone
• contains adenine-uracil pairs

Chargraff's Rule says that

• Adenine will be equal to Thymine
• Cytosine will be equal to Thymine
• Uracil will be equal to Guanine
• Adenine will be equal to Cytosine

Which is NOT a function of DNA?

• to signal when an organisms is in need of a basic necessity
• to carry genetic information from one generation to the next
• to determine the characteristics and traits of an organism
• easily copied for the process of cell division

DNA is copied during

• Translation
• Transcription
• Reproduction
• Replication

The enzyme that attaches the complimentary base pairs to the original strand of DNA is called

• helicase
• polymerase
• replicase
• synthase

The enzyme that unzips the DNA to prepare for replication

• helicase
• replicase
• polymerase
• synthase

DNA replication results in two DNA molecules,

• each one with two original strands
• each one with two new strands
• each one with one new strand and one original strand
• one with two new strands and the other with two original strands
