Document Summary
There"s also a checkpoint kinase for the formation of spindle. P53 transcription factor: just another word for protein . turns on and/or off expression of proteins p21 cdk inhibitor. Starting with bases: was covered in stubbs structures need to know. purines and pyrimidines numbering systems are not required but helpful bases are aromatic: these double bonds represent electrons that are moving around the ring. The ring itself is flat and planar. with 3. 4 a the substituents are in the plane of the ring and that"s important to know as well rings of nitrogen and carbon atoms. Ring n, amino groups and keto groups the important thing about these three entities is that all of them are potential h bonds potential donors are ring n, The amino groups can participate in hydrogen bond donation the acceptors are ring nitrogens, with double bonds associated. The sugar is not aromatic and not flat. the substituents are either projecting above or below the ring.
