Basics of cells |
Every cell must come from a pre-existing cell Must occur to replace old cells or make new cells for growth Just like humans cells go through a life cycle |
|
|
Interphase |
Longest phase(98%) of the cell cycle Includes G1 phase, "s" phase, and G2 phase |
|
|
G1 Phase |
Cell growth |
|
|
"S" phase |
Synthesis phase, DNA replication |
|
|
G2 phase |
Cell growth and prep for division by making centrioles |
|
|
DNA |
Is a nucleic acid Monomer: Nucleotide Three parts: Phosphate, sugar, and nitrogen base(A=T, C=G) DNA is double stranded held together by hydrogen bonds( hold the base pairs of DNA together |
|
|
DNA replication |
DNA "unzips" hydrogen bonds by an enzyme New nucleotides are added to create a new strand of DNA |
|
|
Give the complimentary replicated strand ATG-CCA-TGG-AAC |
TAC-GGT-ACC-TTG |
|
|
Mitosis |
PMAT (Prophase, Metaphase, Anaphase, Telophase) Happens in body cells(Somatic and Diploid) |
|
|
Prophase |
-DNA winds up to form chromosomes -Nuclear membrane(envelope) dissapears -Centrioles appear and send out spindle fibers |
|
|
Metaphase |
-Spindle fibers attach to chromosomes and start to pull towards the centrioles -Chromosomes move to the middles of the cell |
|
|
Anaphase |
Sister chromatids pull apart and towards opposite ends of the cell |
|
|
Telophase |
Sister chromatids reach opposite ends of the cell and unpack into DNA -Nucleus reappears -Cell prepares for final division |
|
|
Cytokinesis |
Cytoplasm divides completely creating two identical daughter cells Animals cells- Cleavage furrow develops Plant cells- Cell plate forms |
|
|
Cancer |
Caused by uncontrolled cell division |
