Document Summary
When an individual gets this prion their brain degrades over time. Prions: unusual infections particles: protein particle with no genetic material (there"s no dna or rna) There is just sequences of polypeptides that form blobs of proetins: its called creutzfeldt-jakob disease in people. Flagellum- a complex structure, made up of proteins. Endospore- protective resting structures, bacteria surrounded by durable cell wall. Resistant to extreme conditions: reproduction: bacteria is asexual( in the form of binary fission) Where one cell will divide and produce two daughter cells. Prokaryotes don"t use mitosis or meiosis, they provide asexually, they have circular chromosomes and double stranded dna: *mitochondria is where we get circular chromosomes. Plants also have circular chromosomes in their mitochondria. Plants also have chloroplast which have circular chromosomes. There are vaccinations to prevent it and antibiotics. We have antibiotic resistance which means when the bacteria can resist the anti biotic. They can evolve and billions of bacteria in our body making us sick.
