Why must the fumaric acid produced in step 6 of the citric acid cycle have a trans double bond to continue in the cycle? Why can't the corresponding cis double bond isomer continue in the cycle?
If 22% of the nucleotides of a DNA molecule are deoxyadenosine and during replication the relative amounts of available deoxynucleoside triphosphates are 22% dATP, 22% dCTP, 28% dGTP and 28% dTTP, which will be limiting to the replication?
