Replication Review Quiz

The bonds holding nucleotides together are called:

• Ionic Bonds

• Covalent Bonds

• Van der Waals Forces

• Hydrogen Bonds

Hydrogen bonds must be ​ (a)   so that DNA can be ​ (b)   by ​ (c)  

• weak
• unzipped
• helicase.

Match the following

• Glues any fragments of DNA together

• Ligase

• Unzips DNA

• Primase

• Places an RNA primer as a starting point

• Helicase

• Adds on brand new nitrogen bases to a DNA strand

• DNA Polymerase

Place the following steps of DNA replication in order:

• Ligase glues together any pieces of the two new DNA strands that were separated.

• DNA polymerase adds on complementary DNA bases to both available strands.

• The RNA primers are removed and replaced with DNA near the end of replication.

• DNA is unzipped by helicase so that replication can begin!

• Primase places down an RNA primer as a starting point for DNA polymerase.

The leading strand is always ​ (a)   The lagging strand is always ​ (b)  

• continuous, and in once piece.
• fragmented, and in several pieces.
