2.6 Prokaryotic and Eukaryotic cells

Question 1

DNA in prokaryotic cells

Answer 1

• 1 chromosome which us supercoiled to make compact

- genes on chromosome are grouped into operons (switched on/off at the same time)

Question 2

ribosomes in eukaryotic cells vs prokaryotic cells

Answer 2

eukaryotic = larger, 80S
prokaryotic = smaller, 70S

Question 3

flagella in prokaryotic cells

Answer 3

• thinner
• chemiosmosis provides energy to rotate filament
• attached to cell membrane by basal body
• rotated by molecular motor

Question 4

reproduction in prokaryotic cells

Answer 4

binary fission

Question 5

reproduction in eukaryotic cell

Answer 5

asexual or sexual

Question 6

structure of DNA in eukaryotic vs prokaryotic cells

Answer 6

eukaryotic = linear 
prokaryotic = circular
