Front

In order to make more cells (which you are constantly doing), you must make a _________ of DNA first!

Back

copy

Front

The first step required in order for DNA to make a copy of itself is to ______________ those hydrogen bonds between the bases.

Back

break

Front

An enzyme called ___________ breaks the hydrogen bonds and unzips the original parent DNA molecule.

Back

DNA helicase

Front

After the DNA is unzipped, _____________ reads the DNA and determines which NEW nucleotides to add to the parent strand.

Back

DNA Polymerase

Front

DNA is unzipped and read at many different sites on the DNA molecule to speed up the replication process. These sites are called ______.

Back

Replication Forks

Front

Since DNA is a 3-Dimensional molecule made of linked nucleotides, it really doesn’t have a “left” or “right”; “up” or “down”.

Back

True

Front

DNA molecules are __________________- meaning the two strands run parallel to one another, but in different directions. (It always looks like one strand is up-side down relative to the other).

Back

antiparallel

Front

A new DNA strand that moves continuously TOWARD the replication fork is known as the ___________.

Back

leading strand

Front

Because the strands are anti-parallel, the ____________ will move AWAY from the replication fork.

Back

lagging strand
