All about DNA
DNA repair
Reading DNA
Regulation of the cell cycle
100
The phase where the nuclear envelope reappears and the chromosomes expand
What is telophase
100
The chromosomes are identical in these
What are sister chromatids
100
Any change in a cell's sequence of DNA
What is a mutation
100
These bases match up and are not C-G
What is A-T
100
Proteins that regulate progression of the cell cycle
What are cyclins
200
The phase in which the cell spends most of its life (G1,S,G2)
What is Interphase
200
These are the four nitrogenous bases of DNA
What are A,T,C,G
200
A mutation caused by the environment are called environmental factors or this
What are mutagenic chemicals
200
The combination of DNA and proteins
What is a replisome
200
These bind with cyclins to transfer phosphate groups
What are kinases
300
The phase where sister chromatids separate
What is Anaphase
300
DNA strands run in this pattern said to be like a divided highway
What is antiparallel
300
The process by which mutations are repaired
What is excision repair
300
DNA bound to nucleosomes are called
What is chromatin
300
The cell cycle is halted to fix repair which is controlled and repaired by proteins
What is cell-cycle arrest
400
The stage in which the cell stops dividing
What is G0
400
The enzyme that unzips DNA and helps mend repairs
What is DNA Polymerase
400
Cells that keep producing even when mutated and are harmful cause
What is cancer
400
A strand has the sequence ATGGTACGGTAA, what strand matches up with this strand
What is TACCATGCCATT
400
Transfer of this activates ATP and gene product, which is completed by cyclins and kinases
What are phosphate groups
500
These are the stages of interphase
What is G0,G1,S,G2
500
Enzymes and other proteins bind to this forming a replisome
What is Replication Origin
500
I am the first line of defense in a cell that also helps proof read and correct mistakes with DNA
What is DNA polymerase
500
One old strand of DNA and One new strand of DNA
What is semiconservative
500
Arrest during this phase indicates problem with the spindle
What is M arrest
