Biochemistry help please!
What is cooperative transition? Does the concept of "cooperativity" help explain the shape of DNA melting curves? What are the forces that stabilize the formation of DNA hairpins and what do they have to do with cooperativity?
Thank you!
Homework Answers
Cooperative transition takes place from B-form DNA to overstretced form S-form DNA. In this procedure, the affinity of the binding sites for a ligand is apparently increased, positive cooperativity, or decreased, negative cooperativity, upon the binding of a ligand to a binding site. DNA go through phase transitions such as melting, unfolding, or unwinding, known as subunit cooperativity. DNA supercoiling can have a strong impact on gene expression as in the negative superhelix density can stabilize cruciform formation.

10. For a given reduced/oxidized molecular pair (X /X), a negative reducing potential suggests that the x has a higher affinity for the electrons than x does X has a higher affinity for electrons than H2 does. X has a lower affinity for the electrons than x does X has a lower affinity for electrons than H2 does.

Congratulations! You have just started working in a brand spanking new biochemistry lab with some very fancy equipment to accurately measure enzyme activities. There is only one problem...You work for an absent minded Investigator who cannot keep track of his inhibitors.

Please help with this
biochemistry question. the first half of the question was whether
or not cyanide would affect oxygen consumption in cells. How would
cyanide affect ATP? Wouldn't it decrease ATP produced?
What do you predict will happen with ATP production in the long run? ATP will stop being produced. ATP will continue to be produced.
