Miscellaneous
100
In a DNA molecule, thymine always pairs with this molecule?
Adenine
100
This is the process by which a cell makes a copy of the DNA in its nucleus.
What is replication
100
Interphase, mitosis, cytokinesis.
What are the 3 main phases (stages) of the cell cycle?
100
In the phase, the nuclear membranes return, sister chromatids relax into a mass of chromatin in the nucleus.
What is Telophase?
100

The location of DNA in Eukaryotic cells.

What is the nucleus?

200

The shape of DNA

What is a double helix?

200

Which phase of the cell cycle does DNA replication occur in?

Interphase/ S phase

200
The phase the cell spends the most time in during cell division
Interphase
200
During this phase of mitosis, the chromosomes line up across the center of the cell, and each chromosome attaches to a spindle fiber at its centromere, which still holds the chromatids together.
What is metaphase?
200
The phases of mitosis in order from when they begin after interphase are these.
Interphase, prophase, metaphase, anaphase, telophase, cytokinesis
300

The part of DNA responsible for the coding of genetic traits in organisms

Nitrogen base sequence

300
Adenine, Thymine, Cytosine, and Guanine
What are the four nitrogen bases?
300
This is the stage during the cell cycle when the cell's nucleus divides into two new nuclei.
What is mitosis?
300
In this phase, the sister chromatids are being pulled apart as spindle fibers shorten.
What is Anaphase?
300
Genetic information is stored in packages of DNA. Humans have 46 pairs of these.
What are chromosomes?
400
Spell out the whole word of DNA
Deoxyribonucleic Acid
400
Why is DNA replication necessary for cell division?
Each cell needs a full set of genetic material (DNA).
400
The phase where cells spend the majority of their time.
What is Interphase?
400
What is the purpose of Mitosis?
To separate the genetic material, start the division process and prepare for the final division (cytokinesis)
400

What are functions of cell division?

Growth, Repair & reproduction

500
The sides of the DNA ladder are made of molecules of deoxyribose and this other molecule?
What is phosphate?
500
What happens at the end of DNA replication?
The cell results in two identical strands of DNA (sister chromatids)
500
These are what are formed during cytokinesis after the pinching part of the process occurs in animal cells.
What are two new daughter cells
500

Centrioles migrate to opposite ends of the cell. The nuclear membrane dissolves. Spindle fibers form.

What is prophase?

500
The regular sequence of of growth and division that cells undergo is know as this.
What is the cell cycle?
