Presentation on theme: "(3) Gene Expression Gene Expression (A) What is Gene Expression?"— Presentation transcript:

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!

5

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

7

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
State 3 differences between DNA and RNA State 3 types of RNA and the main function of each type
