10 important topics on the classic genetics test

1. Famous scientists associated with genetics - Franklin, Griffith, Chargoff, to name a few.
2. The DNA structure: antiparallel and and shaped as a double helix
3. Purines = Adanine and Guanine; Pyramidine = Thymine and Cytosine
4. Deoxyribose and Oxyribose sugars: Oxyribose has an extra oxygen on its second carbon
5. DNA is double stranded and found in the nucleus, RNA is double stranded and found both in the nucleus and cytoplasm
6. RNA is found in many different versions, mRNA, tRNA, premRNA.
7. Procedure of protein synthesis: replication->transcription->translation
8. DNA is always replicated 5' - 3'
9. For transcription, start by finding the TATA box, which is labelled 5'-3.
10. For translation, remember each amino acid begins with Met, because start codon is always AUG
11. Good luck :)
