DNA
Cells must do this before they divide.
Copy their DNA
The two cells produced are described as.
identical daughter cells.
Synthesis
I am very large and I live in the nucleus.
DNA
This term describes the passing of traits from parents to kids.
inheritance
Series of events that cells go through as they grow and divide is called
Cell Cycle
G1 stands for.
growth 1
I am the division of the cytoplasm
cytokinesis
Normal cell division must be.
controlled and coordinated
Mitosis is what number stage in the cell cycle.
second stage.
I am the second phase in mitosis.
metaphase
where are chromatids pulled towards?
one end of the cell
This name is given to cells that have been divided.
daughter cells
divide (unzips)
The structure of a protein is determined by this.
sequence of DNA bases on a gene
Proteins are built at this location.
Ribosomes
DNA
Cell cycle begins right after this event occurs.
cell division
increase in size, build new proteins and organells.
Cytokinesis occurs after these two events.
mitosis and separation of chromosomes
divide
Daughter cells are genetically identical to a parent cell.
TRUE
x shaped chromosomes are pulled by spindle fibres into a ____________________ right down the _____________ of the cell
single line and middle
What happens to the spindle fibres in telophase?
dissolve
There are two reason why cells divide.
tissue growth or repair
I float around in the nucleus
nucleotides
Information found in DNA are called.
instructions
I am a jelly like substance that ribosomes can be found.
cytoplasm
A change or mistake in pairing or order of bases.
mutation
what does S stand for in the interphase process
synthesis
cytokinesis in plants and animals cells are identical.
False
If it gets too crowded for cells what happens?
stop dividing.
Replicated DNA molecules from interphase join together to form.
sister chromatids
this happens to the nuclear membrane after spindle fibres form and attach
dissolve and disappears
I am the fourth phase in mitosis
telophase
This process involves DNA duplicating itself
DNA Replication
Free nucleotides migrate in and form these with the exposed DNA bases
complementary bonds
DNA is found and stuck in this space.
nucleus
The process of DNA being copied to RNA.
Transcription
Achondroplasia is a mutation that affects the entire body called.
dwarfism
The names of the different phases in Interphase
G1, S and G2
What does G2 stand for in interphase?
growth 2
I am formed in animal cells and pinch to form 2 daughter cells.
cleavage furrow
Cancer cells has this characteristic.
uncontrolled and rapid division
sister chromatids of a chromosome are joined together by.

I am the third phase in mitosis
anaphase
elongate
A cell divides to produce two new cells through _______
mitosis
The term for parental DNA that is maintained and not destroyed.
semi-conservative
There are 4 common bases for DNA
Adenine - Thymine - Cytosine - Guanine
This process of mRNA building proteins at the ribosome.
Translation
The study of heredity, which includes, DNA, genes, proteins synthesis, mitosis and meiosis
G1 is the phase that.
the cell grows
Two events happen in the S(synthesis) phase.
Chromosomes copied and DNA is synthesized.
plant cells can not begin division until this is formed.
cell wall
cells stop dividing is called
contact inhibition
Prophase, metaphase, anaphase and telophase relate to what process
My toe sis
contract and shorten
The nuclear membranes do this action during telophase.
reform
substitution, insertion and deletion
this mutation where one base pair is replaced by another is.
substitution
This mutation occurs when one or more base pairs are added.
Insertion
This mutation occurs when one or more base pairs are removed.
Deletion
the name for when a mutation has no effect.
silence
The S phase begins this event
DNA replication
I am the process that occurs after G2 phase
I am formed during telophase in plants and elongate(stretch/lengthen) across the cell
cell plate
this growth factors can trigger cell division.
hormones and nutrients.
Chromosomes condense meaning shorten and thicken is this phase
Prophase
I form and attach to the chromosomes.
Spindle fibres
this phase occurs before cytokinesis begins.
telophase.
These are some of the ways genetic mutations can insert themselves
Silence, Substitution, premature stop and frameshift
A difference amino acid is inserted during protein synthesis is.
substitution
This mutation sends a signals a stop in protein synthesis, resulting in a incomplete stop.
Premature stop
The deletion or insertion which builds completely different proteins.
Frameshift
The full names of DNA and RNA
Deoxyribonucleic acid and ribonucleic acid
The structures needed for cell division are produced in this phase.
G2
Mitosis is divided into these 4 phases.
Prophase, Metaphase, anaphase and telophase
I am the process that happens after telophase is complete.
Cytokinesis
false
I move apart to opposite ends of the cell
centrioles
chromosome are pulled apart into
sister chromatids
Opposite ends of a cell are referred to as.
poles
