How doProkaryotes divide?
|
Binary Fission
|
|
|
What are the 3 stages ofBinary Fission?
|
bidirectional replication of their circular DNA
Cell then elongates anddevelops a septum finally pinches into two new daughter cellss at the septum |
|
|
After replication what initates fission?
|
Protein FtsZ
|
|
|
Eukarytotic Chromosomes are mode up of what?
|
Chromatin
40% DNA 60% Protein |
|
|
Heterochromatin and Euchromatin
|
- more condensed version of the genome that will NOT be expressed
- is the more portion of the genome that will be expressed |
|
|
Chromosome Coiling
lenght if uncoiled? Why coiled? |
2 inches
TO package it neatly inside the nucleus |
|
|
What is Karyotype?
|
The particualur make up of an individuals chromosomes.
|
|
|
Haploid vs Diploid?
|
each somatic cell is diploid -46 chromosomes
gamete is haploid - 23 chr conception n + n = 2n |
|
|
Homologues
|
chromosomes that are the same type. Each has two wo one from the mother and one from the father.
Eeven thought each parent contributes different alleles of those genes. |
|
|
What is the repetitive process of cell growth and division in a eukaryote called?
|
The Cell Cycle
|
|
|
What is the G1 phase for?
|
Primary Growth Phase
Major portion of cell's life |
|
|
G2 phase?
|
Second growth phase
preperation for genomic speration |
|
|
Interphase?
|
The first three phases of the cell cycle (G1, S1, G2)
|
|
|
M Phase?
|
Mitosis (the M phase) is where the cell's replicated DNA are separated in preparation for actual cell division.
|
|
|
S Phase?
|
Where the cell synthesizes a replica of its genome
|
|
|
C Phase, Cytokinesis
|
the phaseof the cell cycle when the cytoplasm divides, and the literal creation of the two daughter cells occurs
|
