CENTRAL DOGMATo supplement the guided notes packet

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!
