Questions on the Sodium Potassium Pump and Enzymes

... active site? For example DNA Ligase forms phosphodiester bonds between Okazaki fragments... What about when one job involves two enzymes ie. DNA Gyrase and DNA Helicase in unwinding the double helix or when an enzyme has two jobs such as DNA Polymerase forming phosphodiester bonds between nucleotides ...

Theories - Origin of Life

... take place. If you are asking this question, it implies that you’re denying this anyways. :) And again, examples have been given ‒ such as the DNA gyrase example I gave above, as well as in your discussion with Luxorien. The body plan must be altered in some way for speciation to happen. Definitely ...

Theories - Origin of Life

... started talking about multiple mutations as well ‒ I will address that below.) Sample calculation: There are several single point mutations in DNA gyrase which is sufficient to confer resistance to quinolone antibiotics. (Which, I will point out for your discussion with Luxorien, is clearly a beneficial ...

topoisomerases and gyrase

gyrase is a special kind of topoII that is present in bacteria to introduce negative supercoils into the DNA. Eukaryotes have nucleosomes to introduce the negative supercoils, so they don't need to have a girase.
