Cell cycle

Series of cell division in eukaryotic cell

1.) the ___ of a cell is its life cycle




2.) cycle which a cell goes through to divide

Mitosis

Process of sorting/distributing chromosomes to daughter cells and creating two nuclei

1.) also known as the M phase




2.) has 4 dinstinct phases

Interphase

Time between divisions, chromosomes aren't visible in nucleus, cell replications happens

1.) cell spends most of its time in this phase




2.) "inter" as in intermissions

G1/G0

Prereplication, grows cells, RNA, proteins, & macromolecules, prepares for S or M phase or preform special cell functions. G0 is stopping point in G1, cell is adult and ready to preform task to sustain organism

1.) Intial phase




2.) "G"1 g as in grow

S

DNA of chromosome replicates identical set for daughter cell

1.) "s" synthesizes new DNA for daughter cell




2.) semiconservative replication

G2

Prepares for mitosis by making RNA and protein

1.) preparation




2.) before M phase

M

Mitosis

1.) "m" for mitosis




2.) last phase of cell cycle

Restriction point

"Point of no return" once cell enters this stage it is committed to the cell cycle

1.) restricted from returning




2.) appears in G1

Cytokinesis

Division of cell

1.) happens after/during mitosis




2.) splitting into 2

Daughter cell

1 cell completes cycle, splits into 2 cells

1.) cell splits into "daughter" of parent cell




2.) result of mitosis and cytokinesis

Nucleotide base pairing

Pairing certain bases with its acceptable counterpart

1.) pairs bases together




2.) ex: adenine and thymine

Hydrogen bond

Bonds bases together

1.) makes a bond




2.) the hydrogen bond between adenine and thymine

Antiparallel

2 lines are parallel but run in opposite directions

1.) similar to parallel, one differnece




1.) "anti" directions

DNA polymerase

Enzyme that catalyzes new DNA strands

1.) maker of new DNA




2.) very accurate

Semiconservative replication

Replicating DNA strands

1.) happens in S phase




2.) DNA polymerase is used

Histone

Is a basic protein with strong positive charges

1.) part of nucleosome 

1.) part of nucleosome

Chromosome

Structure inside nucleus, contains DNA and proteins

2.) has DNA 

2.) has DNA

Chromatin

DNA bounded to a nucleosome

1.) forms chromosomes 

1.) forms chromosomes

Mutation

Change in DNA sequence

1.) ex: cancer




2.) can be silent, harmful, or beneficial

Mutagen

Chemical/radiation that causes mutations

1.) ex: ultraviolet radiation




2.) ex: gamma rays

Excision repair

Process by which mutations are repaired

1.) "repairs" mutations




2.) excises mutated gene

Leading strand/lagging strand

Leading strand is strand where new strand is synthesized, lagging strand is the original that is not continuing to make a new strand

1.) leading strand leads new DNA synthesis




2.) lagging strands stay original

Sister chromatids

2 copies of chromosome

1.) sisters as in more than one

1.) sisters as in more than one

Centromere

Protein at center of chromosome

1.) "centr" sounds like center




2.) part of a chromosome

Aneuploid

Daughter cell with abnormal amount of chromosomes

1.) defect




2.) misshapen cell

Prophase

1st step of mitosis, mitotic spindles form, nuclear membrane breaks down

1.) part of mitosis




2.) 1st step of mitosis

Metaphase

2nd step of mitosis, chromosomes pulled into a ring between 2 poles

1.) part of mitosis




2.) "meta" middle

Anaphase

3rd step, sister chromatids separate & go to the poles

1.) mitosis




2.) a in anaphase a in apart

Telophase

4th & last step, chromosomes expand, nuclear envelope re-forms, cell divides into two

1.) part of mitosis




2.) end of mitosis





Centrioles

Organelles that assist in mitosis

1.) made of microtubules




2.) only in animal cells

(Mitotic) spindles (fibers)

Mircotubules around the nucleus

1.) appears in mitosis




2.) connects to sister chromatids

Spindle poles

Protein at the end of a centriole anchors microtubules

1.) connects to spindle fibers

1.) connects to spindle fibers





Kinetochore

Protein complex inside a centromere

1.) "kine" kinetic 

1.) "kine" kinetic





Cyclins

Proteins that regulate progression throughout the cell cycle

1.) cyclins looks like cycle




2.) helps the cell "cycle" through the phases

Kinases

Enzymes that bind to cyclins

2.) necessary for cyclins to preform

2.) necessary for cyclins to preform

Cell-cycle arrest

When proteins are checking the cell cycle of mistakes/defects

1.) halts the cell cycle to check




2.) "arrests" the cell cycle

Cancer

Uncontrolled cell growth and reproduction

1.) tumor




2.) ex: lung cancer

Checkpoints

Places in cell cycle to check for any mishaps/defects

1.) like a security checkpoint




2.) "checks" for "points" in the phases for defects
