Place these phases in the right order.

Mitosis, Synthesis, Gap1, Gap2, Cytokinesis

What is Gap1, Synthesis, Gap2, Mitosis, Cytokinesis

100

These are the parts of a nucleotide that make up the backbone of the DNA.

What are the sugars and phosphates?

100

These help keep the cell regulated. They are there to make sure cell division occurs accurately and without mistakes.

What are checkpoints?

100

This is a series of steps to divide the contents of  the nucleus. 

What is Mitosis?

100

During DNA replication each strand in the double helix acts as a template for synthesis of a new complimentary strand. This is the word that describes that.

What is semiconservative? 

200

This is the process of dividing the contents of the cell's nucleus.

What is mitosis? 

200

These are the parts of a nucleotide that make up the "rungs" of DNA and determine traits. 

What are the nitrogenous bases? 

200
True or False. 

All mistakes are caught in the checkpoints during cell division.

What is FALSE?

200

This is the division of the cytoplasm resulting in 2 identical daughter cells.

What is cytokinesis?

200

This is the phase in Mitosis that the DNA is replicated. 

What is the S-phase (synthesis) of the cell cycle?

300

This  is the complimentary strand to this single strand of DNA 

3' ATGGCTAA 5'

 What is TACCGATT ?

300

True or False

DNA is a single helix polymer.

What is FALSE?

300

This is what happens when disruptions in the cell cycle lead to uncontrollable division and growth.

What is cancer or tumors?

300

In this phase the spindle fibers align chromosomes along the MIDDLE of the cell.

What is METAPHASE?

300

This is the name of the enzyme that opens up the DNA so it can be copied.

What is helicase?
Remember most enzymes end in -ASE.

400

This is uncontrollable cell growth.

What is Cancer?

400

These are the three components of DNA.

What is a phosphate, a sugar, and a nitrogenous base (ATCG)?

400

If the cell division is not accurate or there are mistakes, this is what happens to the cell if it us caught at one of the checkpoints.

What is cell death or apoptosis.

400

This is the first phase in Mitosis. This is where the chromatin packs into  chromosomes. The nuclear membrane breaks down and the spindle fibers form.

What is PROPHASE?

400

This is another enzyme that works with helicase to open the DNA, read the original template strand, and pair up new bases with the original template of bases before being resealed. 

What is DNA polymerase?

500

This is the part of the cell cycle where DNA is replicated.

What is the S-Phase?

500

True or False? 

All living things share the same 4 nucleotides in their DNA. The difference is the number and order that they are arranged. 

Adenine, Guanine, Thymine, and Cytosine.

What is true?

500

This is one place where the checkpoints take place.

G1, G2, or M 

500

In this phase the spindle fibers shorten pulling the sister chromatids APART and towards the opposite sides of the cell. 

What is ANAPHASE? 

500
True or false?

Mitosis results in 2 identical daughter cells.

What is true?
