DNA Replication

Meselson and Stahl's experiments proved that DNA replicates by which mode?

• conservative

• semi conservative

• dispersive

• none of the above

If the sequence of the 5'-3' strand is AATGCTAC, then the complementary sequence has the following sequence:

• 3'-AATGCTAC-5'

• 3'-CATCGTAA-5'

• 3'-TTACGATG-5'

• 3'-GTAGCATT-5'

Which of the following components is not involved during the formation of the replication fork?

• single-strand binding proteins

• helicase

• origin of replication

• ligase

Which of the following does the enzyme primase synthesize?

• DNA primer

• RNA primer

• Okazaki fragments

• phosphodiester linkage

In which direction does DNA replication take place?

• 5'-3'

• 3'-5'

• 5'

• 3'

The ends of the linear chromosomes are maintained by

• helicase

• primase

• DNA pol

• telomerase

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

Why is DNA important?

• it is very small and very complicated
• it's in everything
• it serves as the blueprint for traits of all living things
• because we eat it every day for energy
