1. (3) Gene Expression Gene Expression (A) What is Gene Expression?
(E) Splicing and post-translational modification
(B) Structure and Functions of RNA
(D) Translation
(C) Transcription

2. Gene Expression (B) Describe the structure of a RNA nucleotide
State 3 differences between DNA and RNA
State 3 types of RNA and the main function of each type

3. Structure of RNA nucleotides
Ribonucleic acid
Structure of RNA nucleotides
Each RNA nucleotides contains:
A phosphate molecule
A ribose sugar
A base

4. ----------- cytosine ----------- uracil ----------- adenine
RNA bases
 Guanine
 cytosine
 uracil
 adenine
Cytosine
Guanine
Adenine
Uracil
No more Thymine!

6. DNA vs. RNA DNA RNA Number of strands present in one molecule
Complementary base partner of Adenine
Sugar present in the nucleotide

8. 3 types of RNA molecules
Messenger RNA (mRNA) carries a copy of the DNA code from the nucleus to the ribosome.
Ribosomal RNA (rRNA) and proteins form the ribosome.
Each transfer RNA (tRNA) carries a specific amino acid to a ribosome

9. Gene Expression (B) Describe the structure of a RNA nucleotide
