Binary fission

• Bacterial cells replicate through process of binary fission
• Main circular chromosome dna replicates, then binds to opposite ends of the cell membrane
• Plasmids replicate, but are NOT evenly distributed
• In binary fission, cell wall lengths therfore bridging the septum and two daughters cells form in similar way to cytokinesis
• 3 domains of life are archea, bacteria and eukaryotes
• Dna differneces: bacteria and archea reproduce through binary fission
• Bacteria contain circular chromosome, one origin for DNA replication
• Bacterial cell wall is peptidpglycan, eukaryotic cell wall are cellulose/chitin
• Eukaryotic have introns, archea sometimes have introns, bacteria doesn't have introns
• Bacteria and archea have circular chromosome
• Histone are present in eukaryotic and sometimes in archea
• Horizontal gene transfer occurs by recombination
• Vertical gene transfer occurs only by sexual reprocution, genes only transferred to offspring
• Log scale is used because of the use of very small and very large numbers due to exponential growth
• Lag phase on a logarithmic graph is when there is no increase I'm bacterial cells
• Log phase on a logarithmic graph is when there is exponential increase in living bacterial cells
• Stationary phase on a logarithmic graph is the plateaued in the number of living bacterial cells this is when the rate of cell division and death rate are equal
• Death of decline phase is the exponential decrease of living bacterial cells, this is becauee the evenvironement becomes toxic and there is a lack of nutrients
• binary fission: circular dna replicates, plasmids replicate, there is division of cytoplasm to produce daughter cell
