Insights into Bacteria Reproduction and Cell Division
Explore the fascinating world of bacteria reproduction through binary fission, conjugation, and mitosis. Uncover the similarities and unique aspects of prokaryotic and eukaryotic cell division processes. Learn how conjugation plays a vital role in transferring genetic information between bacteria cells, aiding in their survival. Delve into the intricate mechanisms of binary fission, mitosis, and the significance of these processes in the life cycle of bacteria.

Bacteria Reproduction By Brian Hess, Daniel Dutton, and Aidan Scholz
Overview Partner 1 Binary Fission Mitosis Similarities of Binary Fission and Mitosis Partner 2 Conjugation Unique Eukaryotic cells Similarity between conjugation and Meiosis Partner 3
Prokaryotic Asexual Reproduction Binary Fission- division of a prokaryote into two daughters, reproduction Bacteria grows to twice its typical size, then undergoes fission Endospore- dormant prokaryote, used to survive in harsh environments BH
Mitosis Eukaryotic cell division Creates 2 identical body/somatic/diploid cells Consists of Interphase, Cell Division, and Cytokinesis Interphase Replicate DNA and grow 90% of Mitosis Cell Division Cell undergoes prophase, metaphase, anaphase, and telophase Cytokinesis Cell splits, nuclear envelope reforms completely BH
Cell Division Prophase DNA coils into chromosomes Metaphase Spindles attach to chromosomes from centrioles Anaphase Chromosomes pulled apart Telophase Chromosomes return to chromatin BH
Similarities of Binary Fission and Mitosis Produce 2 identical daughter cells Require growth Exponential: 1,2,4,8,16,32,64... BH
Conjugation Prokaryotic DNA copying Bacteria copies DNA to each other Bridges Prokaryotes transfer their genes using bridges made of plasmid Hollow and connect to the ends of 2 bacteria cells Antibiotics Conjugation transfers genes that code against antibiotic Helps the bacteria fight off Antibiotics and not go extinct Daniel Dutton
Why conjugation is important Allows DNA to be transferred from one Bacteria cell to another without reproduction Transferring Genetic codes to protect against antibodies The point of Transferring Helps Bacteria survive conditions it normally can't Daniel Dutton
Making Unique Eukaryotic Cells Through Meiosis Genetic info transferred through reproduction Creates haploid gamete cells with one set of 23 chromosomes Use reproduction to create "offspring" Mutations Mutations allow us all to develop differently Cell replication 2 cells replicate to make one making it completely different than both original cells (unique) Daniel Dutton
Conjugation and Meiosis Both send Genetic Material to another cell Conjugation uses plasmid tubes Meiosis uses reproduction Both are sending genetic code to another cell for use Exact and Unique Conjugation creates unique prokaryotic cells by exchanging genes Meiosis Creates Completely unique copies of genetic info Daniel Dutton
What are diploid and Haploid cells Diploid cells made during mitosis + have 2 sets of parent chromosomes Haploid Cells made in meiosis + have 1 set of unpaired chromosomes Diploid=body cells Haploid=sex cells AS
