DNA

100

What substances alter the DNA strand during DNA Replication?

Enzymes

200

What is the first step of DNA replication (aka what must the strand do first?)

Unzip

300

What shape does DNA take?

Double Helix

400

How do the four bases pair up?

A - T , C - G

500

These are the four nitrogenous bases

Adenine, Thymine, Cytosine, Guanine

General Mitosis

100

The cell cycle results in two genetically _________ cells.

Identical

200

Why is Cellular division important?

Allows for creation of new cells 

300

What thick region forms between cells during telophase

cleavage furrow

400

What type of reproduction is occurring during mitosis?

Asexual

500

What are the fibers called that connect the chromatids to the centrioles?

Spindle Fibers

Interphase

100

Which phase does the cell spend most of its life in?

Interphase

200

During interphase, DNA has replicated and appears as a loosely coiled mass known as ___________.

Chromatin

300

Is the nuclear membrane still intact during interphase?

Yes

400

What two things occur during Interphase

Cell Grows and DNA Copies

500

If an error in replication occurs, what may happen in the cell?

cancer develops

Mitosis Phases

100

List the 5 phases of cell division in order.

Interphase, Prophase, Metaphase, Anaphase, Telophase

200

At which phase do the chromosomes become visible in the cell?

Prophase

300

In which phase do the nuclear envelopes reform around the separated chromosomes?

Telophase

400

At what phase in cell division do the spindle fibers pull the chromosomes to opposite poles of the cell?

Anaphase

500

Spindle fibers attach to the centromeres and chromosomes line up in the middle of the cell during this phase of cell division.

Metaphase

Binary Fission, Mitosis, or Both

100

Cleavage develops before seperation.

Both Binary Fission and Mitosis

200

Involves the dissolving and reformation of the nucleus.

Mitosis

300

Results in two identical daughter cells.

Both Mitosis and Binary Fission

400

Cellular Division that occurs in eukaryotic cells.

Mitosis

500

Cellular Division that occurs primarily in Bacterial Cells

Binary Fission
