DNA Replication and Transcription

What type of replication does DNA go through

• semiconservative

• conservative

• dispersive

• s-phase

Catalyzes the breaking of hydrogen bonds in Replication

• RNA polymerase

• Helicase

• DNA polymerase III

• DNA polymerase I

Stabilizes single stranded DNA

• Sliding clamp

• topoisomerase

• primase

• single strand DNA binding protteins

Catalyzes the synthesis of an RNA primer

• sliding clamp

• DNA ligase

• Primase

• DNA polymerase III

Short DNA fragments that are attached to the primer. They also make up the lagging strand

This protein will remove the RNA primer and replace it with DNA

Which of the following units are repeatedly joined together to form a strand of DNA?

• amino acids
• nucleotides
• fatty acids
• polysaccharides

The enzyme that unwinds 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

Nitrogenous bases are joined by which type of bond?

• polar bonds
• ionic bonds
• covalent bonds
• hydrogen bonds
