Do You Know Who is Robert Hooke?
Suggestion for experiment:
1. Prepare slide of onion epidermal cell and cells of Hydrilla sp. leaf to study a plant cell structure.
2. Prepare slide of human cheek cells to study an animal cell structure.
3. State the technique that you use in these experiment..

2.2.1 State structures which are involve in the process of protein synthesize such as enzyme in the passage below.
Genetic material for a type of enzyme will be synthesize found in __________________. Double Helix
DNA unzip and a RNA chain which carry the genetic code move out from the nucleus to
______________ Protein which has been synthesize by __________________ will be sent to
_____________________________ and transported to ________________________ by
________________ . From __________________ protein which has been modified transported out of
the cell and applied at targeted organs.
Based on the above statement what is the conclusion ?
