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
