In a single circular loop not associated with proteins

Question 6

Plasmids

Answer 6

Small loops of DNA which can be shared between cells usually containing useful genes

Question 7

Cell wall PROKARYOTIC

Answer 7

Made of murein - polysaccharide and peptide mix .

Question 8

Flagellum

Answer 8

Used for locomotion

Question 9

Membrane infold (mesosome)

Answer 9

Increased surface area for respiration or photosynthesis to take place

Question 10

Binary fission

Answer 10

Step 1 - DNA and plasmids replicate. Plasmids can be replicated many times
Step 2 - At the same time the cells elongate and as it does so the two DNA molecules go to opposite side
Step 3 - Cytoplasm begins to divide and new cell walls begins to form
Step 4 - The cytoplasm divides to produce to daughter cells. Each contain an identical DNA loop but can contain a rigged number of plasmid copies.
