Transcript Cell Parts: Protein Synthesis

Catalyst: “Remembering 9/11”

Where were you when you found out about the terrorist
attacks on the world trade center? How did you feel?
Have your feelings about the incident changed?
Cell Parts: Protein Synthesis

DNA (Deoxyribonucleic Acid):

“Master blueprint”, genetic code

Prokaryotic: DNA in nucleoid

Eukaryotic: DNA in nucleus
Cell Parts: Protein Secretion

Vesicles containing proteins are not transported across
the cell membrane by previously learned mechanisms.

Exocytosis: the process
of exporting materials
out of the cell via a
vesicle
“Outside”
Endocytosis: the process
of importing materials
into the cell via a vesicle
“Inside”
Vesicle: a small
molecule within a cell
enclosed by a lipid
bilayer

Cell Parts: Protein Synthesis
Nuclear Pore
Nucleus
Transcription & Translation: DNA instructs

DNA
RNA
Rough E.R.
Ribosome
the synthesis of a protein.
Nucleolus
1.
Nucleolus synthesizes ribosome
2.
Ribosome attaches to rough E.R.
3.
RNA copies DNA (Transcription)
4.
RNA travels through nuclear pore to ribosome
5.
Ribosome decodes RNA into a protein
(Translation)
Golgi Body
6.
Protein travels through rough E.R. to fold into a
complex 3D shape
7.
Protein travels to Golgi where it is packaged into
a vesicle
8.
Plasma Membrane

Vesicle travels to plasma membrane & is
secreted through exocytosis
