Genetic Code/Protein Synthesis

How is this information Used?

Proteins Synthesis

Step One: Transcription of Gene

Process: Several steps

New molecule formed - Messenger RNA or mRNA

Step 2 - Translation

- mRNA

- transfer RNA (tRNA)

- ribosomal RNA (rRNA) (RNA and protein)

1) Start

2) Elongation of chain

3) Stop

Why so important?

Regulation/Control

Transcription:

Translation:

Carbohydrate metabolism ----> ATP

Fate of glucose

glucose breakdown

1) glycolysis

2) Krebs cycle

3) e transport chain

• Complete breakdown (oxidation):

C6H12O6 + 6O2 +36-38 ADP + 36-38 -->36-38 ATP + 6O2 + 6H2O

Control
