Aims

Central Dogma
AIM: What is the Central Dogma of protein synthesis?

• DNA -> RNA -> Protein

Transcription
AIM: How is DNA transcribed into RNA and why is this necessary?

• In the nucleus

Translation
AIM: How are mRNA condons translated into amino acids to form polypeptides? 

• At ribosomes

Gene Mutations
AIM: What is a gene mutation and how does it differ from a chromosomal mutation. 

• gene mutations affect ONE protein
• gene mutations must occur in gametes to affect offspring
• point mutations affect ONE nucleotide and one reading frame
• Additions and deletions of nucleotides cause frame shifts and affect all of the following reading frames.

Gene Expression
AIM: What is gene expression and what does this tell us about the DNA in all of our cells?

• EVERY cell contains ALL of your genetic information and the instructions for ALL of the proteins your body makes.
• Cells only EXPRESS certain genes, they are turned on and off like switches
