Prokaryotic Cells

Question 1

Structure

Answer 1

Cytoplasm lacks membrane-bound organelles

Smaller ribosomes (70 S)

No nucleus , no histone proteins- free-floating circular DNA

Cell wall contains murein (a glycoprotein)

Plasma membrane mainly made up of lipids and proteins

Plasmids are small loops of DNA

Flagella

Question 2

Plasmid

Answer 2

Small loop of DNA that is separate from the main DNA that contain genes that can be passed between prokaryotic such as the antibiotic resistant gene

Question 3

Capsule

Answer 3

Surrounded by a final outer layer known as a capsule to help protect bacteria from dying by attack cells of the immune system

Question 4

Flagellum

Answer 4

Long, hair like structure that rotates enabling movement

Question 5

Binary Fission

Answer 5

Circular DNA & plasmids undergo DNA replication

Parent cell divides into two (cytoplasm is roughly halved)

Two daughter cells contain:
Single copy of circular DNA
Varied amount of plasmids (although this is regulated)
