Cell Cycle
This word describes G1, S, and G2, all together.
Interphase
The shape of a DNA molecule.
a double helix
Which bases pair together in DNA? Give both
A-T, C-G
RNA contains this sugar, which is different from the one in DNA.
ribose
Which phase of mitosis is where chromosomes start to condense?
prophase
This phase of the cell cycle is when DNA replication occurs.
S phase
These are the three components of a nucleotide. (Use the specific name of the sugar!)
phosphate group, deoxyribose, and a base
DNA replication occurs in this part of a cell.
the nucleus
If a DNA strand is the code TAG, this is the RNA code.
AUC
In which phase of mitosis are the sister chromatids pulled apart?
anaphase
The phase during which organelles replicate and the cell mainly grows.
G1
This makes up the backbone of DNA
Sugar and phosphate
This enzyme "unzips" the DNA.
Helicase
Where are proteins made?
ribosome
What is the name for uncontrolled cell division?
cancer
The phase during which the cytoplasm divides.
cytokinesis
Is an organism has 20% Thymine, how much Adenine is present?
20%
These weak bonds occur between bases in a strand of DNA
hydrogen bonds
These are the three-letter words that code for an amino acid.
codons
What type of mutation occurs here?
AUG CGC CAC CGU
AUG CCC ACC GU
deletion
These are the four phases of mitosis in order.
Prophase, Metaphase, Anaphase, Telophase
If an organism has 10% Adenine, give me the percentages of the other 3 bases.
10% T, 40% G, 40% C
How is DNA semi-conservative?
Half of the replicated strand is old, half is new.
What are the 2 steps in protein synthesis and what happens in each?
transcription- copies DNA into mRNA
Translation- turns mRNA into amino acids/protein
Give an example of a beneficial mutation
any trait in an animal that would increase chance of survival like: better camouflaged color, longer neck to reach food, etc.
