|
Difference between and what are the purines and pyrimidines?
|
PURine As Gold
CUT the PYrimidine -Purine = Adenosine, Guanine -Pyrimidine = Cytosine, Thymine, Uracil |
|
|
What is different betw/ Thymine and Uracil?
|
Thymine is methylated - this makes it more stable then the uracil.
|
|
|
Bonds between bases properties and associations?
|
GC is triple
AT is double Stronger triple is in thermophile AT weaker is in Promoter regions (TATA & CAAT boxes) |
