DNA plays this role in the cell's function.
What is GENETIC MATERIAL.
100
Why was this article published?
To share the discovery of the structure of DNA.
100
What are the two main parts of the cell cycle?
Interphase and mitosis
100
This is the phase during which identical chromosomes are pulled to the opposite sides of the parent cell.
What is ANAPHASE?
100
Before a cell divides it is a ______ cell. After it divides it is a ________ cell.
PARENT and DAUGHTER cell
200
A DNA complete DNA strand is a) single stranded b) double stranded c) triple stranded
double stranded
200
These two scientists who discovered DNA's structure.
Who are WATSON AND CRICK
200
This part of the cell cycle takes the longest.
What is INTERPHASE
200
Chromosomes condense during this step/phase.
What is PROPHASE
200
This is a structure in a cell made up of DNA and proteins, it is also the shape DNA takes when condensed.
What is a CHROMOSOME
300
In DNA base-pairing, Adenine (A) binds with ______ and Guanine (G) binds with _____
Thymine (T) and Cytosine (C)
300
Does DNA have a right-handed or left-handed orientation for its helix?
right-handed
300
What three things does a cell do during interphase?
Grow, replicate DNA, get ready to divide (makes more organelles)
300
This is the phase during which a cell divides its cytoplasm and the cell membrane separates the two daughter cells.
What is CYTOKINESIS
300
DNA is copied during interphase in a process called...
Replication
400
Why can both strands of DNA be copied at the same time and produce the exact same molecule?
The base-paring rules make it so that each strand of DNA can be a template to be copied.
400
What year was DNA's structure discovered? a) 1933 b) 1943 c) 1953 d) 1963
c) 1953
400
What amount of DNA is present in a cell at the end of interphase? a) double the normal amount b) half the normal amount c) a quarter of the normal amount d) three times the normal amount
a) double the normal amount, the DNA was copied!
400
This is the phase during which the chromosomes decondense and the nuclear membrane reforms. After this phase, it's like the parent cell has two nuclei.
What is TELOPHASE?
400
The piece of the backbone and a single nitrogenous base together are known as a
nucleotide
500
DNA's backbone is made up of what two molecules?
Phosphates and sugars
500
These type of chemical bonds hold together base-pairs.
HYDROGEN BONDS
500
What are the steps of mitosis, in order!
prophase, metaphase, anaphase, telophase, cytokinesis
500
This is the phase during which the chromosomes line up along the equator of the cell.
