divided
3. ______ Chromatids line up along the equator
4. ______ What is the name of the structure that

reforms and the spindle breaks down.
6. ______ is found in animal cells, and is thought
to produce the spindle fibers that help separate

DNA Replication- Place the following in the correct order:
A.
Free nucleotides in the nucleus join with the correct bases.
B.
2 new molecules of DNA (each contain an original & a new strand) become twisted and take the form of
a Double Helix
C.
Each ½ serves as a pattern for the formation of a new DNA chain.
D.
Double helix untwists, enzyme “Helocase” breaks the H bonds, 2 nucleotide chains begin to separate
like a zipper.
E.
The 2 new DNA molecules are now called “Sister Chromatids” and remain stuck together until the cell
divides.
