100
Cell cytoplasm divides
What is cytokinesis?
100
Long, thin fibers of DNA and proteins (that resembles spaghetti).
What is chromatin?
100
Chromosomes are unwinding and become enclosed in the nucleus, and the cell begins to divide
What is telophase?
100
Chromosomes before mitosis = 46. Chromosomes at end of mitosis in each cell =
What is 46?
100
Plant cells use this to divide
What is a cell plate?
200
DNA replicates
What is the S phase?
200
One half of a duplicated chromosome
What is a sister chromatid?
200
Chromosomes are lined up on the cell's equator
What is metaphase?
200
Cells produced after mitosis
What is 2?
200
What is the pinching of the cytoplasm called?
What is a cleavage furrow?
300
The nuclear membrane fizzles away and the chromosomes condense.
What is prophase?
300
Holds two sister chromatids together
What is a centromere?
300
The cell's chromosomes become visible, the nuclear membrane disappears, and the centrioles move to opposite sides of the cell
What is prophase?
300
The sugar and phosphate portions of a DNA molecule function MAINLY to do which of the following?
A. Store and transmit information about an organisms traits. B. Attract the units that are used to create new DNA molecules. C. Provide the structural support for the sequence of nitrogenous base pairs. D. I am so lost in Biology!

Atherosclerosis is a disease that constricts blood flow and, therefore, oxygen supply to target organs. A major component of atherosclerosis is the excessive reproduction of smooth muscle cells of the blood vessels. Certain drugs may have the potential to reverse or prevent the unregulated reproduction of the diseased blood vessel cells. Which of these processes is the most likely target of these drugs?
What is Cell division?
400
The stage that includes G1, S, and G2
What is interphase?
400
Visible structure seen beginning in prophase
What is a chromosome?
400
Chromatids are pulled apart and become individual chromosomes
What is anaphase?
400
What is the name of the enzyme that cuts hydrogen bonds during DNA Replication?
What is Helicase?
400
Eukaryotes use these two steps to divide
What are mitosis and cytokinesis?
500
Cell preparation for division occurs
What is the G2 phase?
500
Nucleic acid that makes up the bulk of a chromosome
What is DNA?
500
Spindle fibers appear and attach to centromeres
What is metaphase?
500
How many chromatids in a chromosome
What is 2?
500
Uncontrolled cell growth
What is cancer?
