A gram-negative cell wall consists of_ A) cholesterol and peptidoglycan B) peptidoglycan and cellulose C) a thin layer of peptidoglycan surrounded by a capsule D) a thin layer of peptidoglycan surrounded by an outer membrane conta lipopolysaccharides E) a thick layer of peptidoglycan surrounded by an outer membrane cont lipopolysaccharides Q.6. Plasmids A) are transferred from one bacterium to another by conjugation B) often contain antibiotic resistance genes C) allow bacteria to survive adverse conditions D) replicate independently of the main chromosome E) All of the listed responses are correct. Q.7. Which of the following is a difference between bacteria and archa A) Only bacteria have circular chromosomes B) They have different chemicals in their cell membranes and cell wall

Explanation / Answer

Q4. Prions are abnormally shaped proteins that are thought to cause disease by inducing similar but normally shaped pro… the brain to adopt the abnormal form( prions disease examples: Mad cow disease, Kuru etc.)

Q5. A gram negative cell wall consist of a thin layer of peptidoglycan surrounded by an outer membrane contain lipopolyscaccharides.

Q6. Plasmids (are extra-chromosomal genetic material which ) are transferred from one bacteria to another by conjugation, often contain antibiotic resistance genes, allow bacteria to survive adverse conditions and replicate independently of the main chromosome.

Q7. The difference between bacteria and archae is they have different chemicals in their cell wall and cell membrane.( bacteria have peptidoglycan in their cell wall archae have different form of lipid bonding in membrane.
