The flow of genetic information from DNA to RNA to protein
Initially, the central dogma of biology was simply thought of as
DNA mRNA protein

However, that has been expanded…
DNA RNA Protein
transcription translation
Blue words = initial / classic understanding
Environment
Orange words = new understandings
RNA can be autocatalytic (cut it self up)
Reverse transcription
Proteins can ‘force’ other proteins to mimic themselves. Ex: Prion Diseases

What do all those nitrogenous bases mean?
On the RNA strand, each bracket contains 3 nucleotides.
3 nucleotides are called a codon, each codon represents an amino acid.
There are 64 (43) possible code words which is more than enough to code for the 20 amino acids

Now it’s your turn..
You should be able to use the notes you took for homework to complete the questions up through the elongation stage of translation.
Remember: There are lots of resources on the blog to help you!
