In a DNA molecule, thymine always pairs with which 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 animal cells.
What is the nucleus?
200

It is a double helix.

What is the structure of DNA?

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.

What is prophase?

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 scientists that discovered DNA structure are?
Watson & Crick
300

They include Adenine, Thymine, Cytosine, and Guanine.

What are the four nitrogenous 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

What is Deoxyribonucleic Acid?

400
Why is DNA replication necessary for cell division?
Each cell needs a full set of genetic material (DNA).
400

The phase in the cell cycle 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 the 3 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. 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?
