Cellular Reproduction
For a cell to reproduce...
-parent cell=
-daughter cells=
To divide, a cell must:
1. Copy its genetic material (make 2 nuclei)
2. Divide everything else into 2 groups.
Genetic Material composed of DNA in the form of chromosomes=
Prokaryote Reproduction
-how bacteria multiply
-1 circular DNA Molecule
-replication=
-Binary Fission=
-see fig. 8-5
Eukaryote Reproduction
-how multi-celled organisms grow
-multiple chromosomes
-ploid (n)=
Chromosome Anatomy:
1. Centromere=
2. Telomere=
Gene=
-Homologous chromosomes=
-Allele=
-Diploid # or 2n
-c’some replication= 4n
-sister chromatids=
-c’some reduction=
-haploid (1n)=
-homologue=
-Genome=
-Karyotype=
Cell Cycle=
1. Interphase=
-replication
2. Mitosis (M-phase)=
1. Karyokinesis=
2. Cytokinesis=
Mitosis in Detail:
-simple cell division
-division of one 2n cell into two 2n cells.
-occurs in somatic cells (2n)
Steps of Mitosis: -fig. 8-8
1. Karyokinesis
1. Prophase
2. Metaphase
3. Anaphase
4. Telephase
-spindle fiber structure=
-metaphase or equitorial plate=
-aster=
2. Cytokinesis
-2 types of cytokinesis
1. Cleavage=
-cleavage furrow=
2. Cell Plate Formation=
