ENDOMEMBRANE SYSTEM
IN PROK
Chromosomes -Long circle dsDNA, 5000
bp long
-Contain information
E. Coli Strains -Pathogenic H57:O7
-Beneficial K12
-Lab Strains DH5a
4600 chromosomes, 4600
genes
Plasmids -Small circles of dsDNA; 1-
100 copies
-Resistance (suppress
function of antibiotics)
-Fertility (DNA transfer)
-Having plasmids = better
in extreme cases, otherwise
reproduce slowly
Ribosomes 7000-70,000/ cell
Make new proteins
Having MORE ribosomes =
faster reproduction
70S RIBOSOME
234; 121//rRNA rProteins
Inclusion Bodies Stores nutrients in big
clumps
Helps cell move to where
nutrients are
IN EUK
Nucleus Takes up 6% volume
Has:
- Chromatin
- Pores
- Envelope
- Nucleolus (2 layers
+ inner fluid +
lamina + pores x
3000)
Makes RNA, assembles
ribosomes
Plasma Membrane Holds everything inside

OneClass has been such a huge help in my studies at UofT especially since I am a transfer student. OneClass is the study buddy I never had before and definitely gives me the extra push to get from a B to an A!

Balancing social life With academics can be difficult, that is why I'm so glad that OneClass is out there where I can find the top notes for all of my classes. Now I can be the all-star student I want to be.

As a college student living on a college budget, I love how easy it is to earn gift cards just by submitting my notes.
