toutomer Flashcards
What is a tautomer
isomers that exist together in equilibrium and are readily interchanged by migration of an atom or group within the molecule
structural isomers that differ in the location of protons
prototrophic tautomers
What tautomerism for is common in ketones?

Minor Nucleosides in DNA: Modification is done after
DNA synthesis
5-Methlycytosine is common in what and also found in what?
in eukaryotes, and found in bacteria
N^6-methyladenosine is common in
bacteria but not found in eukaryotes
What is an epigenetic marker?
- Way to mark own DNA so that cells can degrade foreign DNA
- Way to mark which genes should be active (eukaryotes)
Helps to understand could the environment turn genes on and off in an inheritable manner?
Inosine is found in what RNA
TRNA
- Way to mark own DNA so that cells can degrade foreign DNA
- Way to mark which genes should be active (eukaryotes)
Helps to understand could the environment turn genes on and off in an inheritable manner?
What is an epigenetic marker?
Pseudouridine is found in what RNA
tRNA and rRNA
