Overview Binary Fission Endospore Conjugation Meiosis Spreading of diseases Antibiotics MRSA  Bacteria's resistance to drugs

Binary Fission AC Prokaryotic replication Does not involve exchange of genetic information Double in size Replicates DNA Produces two identical cells 

Endospore AC Prokaryotic replication Has a thick wall The wall encircles the DNA and a part of the cytoplasm Can survive for months to years  Prokaryotes survive hard conditions 

Eukaryotic process of Mitosis AC  Parent cell divides to produce two identical daughter cells  In the Nucleus Uses the process of Cellular Division

Eukaryotic process of Mitosis AC Single-cell organisms reproduce by dividing Interphase takes up most of the cell cycle  Increased numbers of chromosomes Replication, segregation, and cytokinesis occur

HV Conjugation 2 prokaryotes exchange genetic information by conjugation  A hollow bridge forms Plasmids transfer genetic information 

Importance's of Conjugation HV Importance's of Conjugation Adapt to new environments Able to survive from fatal antibiotics   Helps bacteria evolve 

Eukaryotic process of Meiosis HV Eukaryotic process of Meiosis Chromosomes creates copy of itself before meiosis Parent cell divides twice Produces 4 similar haploid daughter cells

Eukaryotic process of Meiosis HV Eukaryotic process of Meiosis Produces sex cells or gametes Contains half the number of chromosomes of the parent cell Includes recombination/crossing over

How do diseases spread? Destroying living cells Sammi Rae How do diseases spread?  Destroying living cells Releasing chemicals that disrupt homeostasis Destroy affected cells & tissues  Tissue damage provoke response from immune system

What do we use antibiotics to treat? Sammi Rae What do we use antibiotics to treat? Penicillin & Tetracycline Block bacterial growth & reproduction Disrupt proteins or cell process

Amoxicillin Treat bacterial infections Sammi Rae Amoxicillin Treat bacterial infections Killing bacteria -> preventing growth Bloating, chest pain, bleeding gums  Anaphylaxis UTI, strep throat, pneumonia

Azithromycin Treat certain bacterial infections Sammi Rae Azithromycin Treat certain bacterial infections Killing bacteria -> preventing growth Back, leg, or stomach pains Bronchitis, pneumonia, STD

MRSA (AH) It can cause infections which are hard to control The is real name Methicillin-resistant Staphylococcus aureus resistant to antibiotics 

MRSA (AH)  Symptoms=a boil of puss, a spot that is painful when touched, a bump that is red, swollen, and hot Treatments=Methicillin, Linezolid, Mupirocin, Daptomycin, etc. Hospital Problems=pneumonia, bloodstream infection, and surgical site infections

"Superbugs" (AH) They transfer drug-resistant genes from one bacterium to another The superbugs are resistant to whole groups of antibiotics No antibiotics today can harm superbugs

How Bacteria can develop resistance to drugs? (AH) Evolution helped bacteria become more resistant to drugs Antibiotics led to a process of natural selection of bacteria The bacteria survive and multiply to reduce or eliminate the effectiveness of the antibiotics

What is the offspring of Binary Fission? AC A. Identical to parent B. Completely unidentical to parent  C. 1 identical daughter cell  D. 1 unidentical daughter cell

In what kind of cells does Mitosis occur? AC A. Blood Cells  B. Prokaryotic  C. Somatic and Eukaryotic cells D. Mitochondria
