What is DNA
|
deoxyribonucleic acid
double-stranded polymer made up of nucleotides The base (in triplets) in many portions of the DNA code for amino acid sequences that make up protein products |
|
Chromatin
|
the loose, uncoiled state of DNA during interphase
|
|
Chromosomes
|
the condensed, tightly coiled molecules of DNA visible starting in Prohpase of both mitosis & meiosis
|
|
Sister chromatids
|
gnetically identical copies of a chromosome attached at the centromere
|
|
Centromere
|
part of the chormosome that connects the sister chromatids, consists mostly of repetitive satellite DNA
|
|
Centrosomes
|
centers of microtubule organization; duplicated during G2 of interphase & migrate to opposite poles during cell division to pull chomosomes apart
|
|
What are the 2 main functions of mitosis?
|
Growth & repair/replacement of multicellular organisms
|
|
Interphase consists of
|
Gap 1
Synthesis Gap 2 |
|
Gap 1
|
cell growth/metabolic activity. DNA
|
|
Synthesis
|
DNA replication
|
|
Gap 2
|
cell gets bigger, further preperation for division, centrosomes duplicate
|
|
What are the phases of mitosis
and can you learn all of them by the midterm you fucking idiot |
Prophase
Prometaphase Metaphase Anaphase Telophase & Cytokinesis |
