Question

Epigenetics can account for all following EXCEPT

A.	Genomic imprinting
	B.	Inactivation of X-chromosomes
	C.	Tissue specific differences
	D.	Sickle cell anaemia
	E.	None of the above

All epimers are stereoisomers T/F?

The principal function of the TCA cycle is to;

A.	Generate carbon dioxide
	B.	Transfer electrons from the acetyl portion of acetyl CoA to NAD+ and FAD
	C.	Oxidize the acetyl portion of acetyl CoA to Oxaloacetate
	D.	Generate heat from the the oxidation of the acetyl portion of acetyl CoA
	E.	Dispose of excess pyruvate and fatty acids

Answer 1

Epigenetics account for a secondary layer of variation that is more tissue-specific genomic imprinting ,miRNAs , paramutation, X inactivation and sickle cell disease is the result of genetic mutations in the β-globin gene and was the first disorders to be approached with epigenetic-specific therapy.

So the correct answer is - none of the above .

All epimers are stereoisomers. Epimers are tupr of diastereomers and they are a stereoisomer that are not mirror image . True

Answer D.  energy is generated directly from acetyl CoA and it provides NADH for the electron transport chain .Gives energy in the form of GTP from substrate level phosphorylation
