1. Bacteria Reproduction

2. Asexual Reproduction - Offspring are identical to parent (CLONE) - Carried out by Prokaryotes and Eukaryotes - Simple & Efficient - Binary Fission and Mitosis

3. Sexual Reproduction - Offspring is created from 2 diploid parents combining haploid gametes - Carried out by only Eukaryote - Offspring has genetic traits from both parents (23+23=46) - Meiosis

4. Complexity and Steps AsexualSexual SimpleComplex Not manyMany steps Stepswhere things can go wrong

5. Time AsexualSexual Happens fastCan take more And efficienttime, many checkpoints

6. Parent and Offspring AsexualSexual One Parenttwo parents One OffspringUsually one offspring Not muchRequires a lot Energy neededof energy, time Requires mating and competition

7. Genetic Diversity AsexualSexual Little to noneCan quickly (caused byadjust genetic Mutations)diversity by (Meiosis Xover)

8. Cell Cycle and Timeline Lag Phase - cells may be growing in volume or mass, synthesizing enzymes, proteins, RNA, etc., and increasing in metabolic activity. Log (Exponential) Phase - phase of growth is a pattern of balanced growth wherein all the cells are dividing regularly by binary fission, depending on environment Stationary Phase - Population growth is limited by one of three factors: 1. exhaustion of available nutrients; 2. accumulation of inhibitory metabolites or end products; 3. exhaustion of space Death phase - the number of viable cells decreases

9. Cell Cycle and Timeline

10. Binary Fission During binary fission, the single DNA molecule replicates and both copies attach to the cell membrane. Next, the cell membrane extends between the two DNA molecules. Once the bacterium just about doubles its original size, the cell membrane begins to pinch inward. A cell wall then forms between the two DNA molecules dividing the original cell into two identical cells.

12. Transformation Transformation is the uptake and expression of foreign DNA. Can be good and bad! Why?

13. Conjugation During conjugation, a hollow bridge forms between two bacterial cells, and genes move from one cell to the other. This transfer of genetic information increases genetic diversity in populations of bacteria.

15. Transduction Transduction is the process by which DNA is transferred from one bacterium to another by a virus. DNA bacteriumvirus The virus is known as a Bacteriophage
