HELP ASAP!!QUESTION 2 How does hydrolysis of ATP associated with Bera-tubulin affect the assembly of microtubule protofilaments?
ATP does not bind beta-tubulin and therefore does not affect on the formation of microtubule protofilaments.
ATP hydrolysis changes the conformation of the tubulin heterodimer, which weakens the bonds between the tubulin heterodimers to destabilize
the protofilament
ATP hydrolysis promotes the assemble of the microtubule organizing center.
ATP hydrolysis phosphorylates Tau, which stabilizes microtubules.

In 1959, doctors began using the powerful antibiotic methicillin to treat infections of staphylococcus aureus, but within two years, methicillin-resistant strains of s. aureus (mrsa) appeared. how did the resistant strains of s. aureus emerge? in 1959, doctors began using the powerful antibiotic methicillin to treat infections of staphylococcus aureus, but within two years, methicillin-resistant strains of s. aureus (mrsa) appeared. how did the resistant strains of s. aureus emerge? staphylococcus aureus bacteria that were able to synthesize cell walls using a protein that was not affected by methicillin survived the methicillin treatments and reproduced at higher rates than did other individuals. over time, these resistant individuals became increasingly common. in response to treatment of staphylococcus aureus infections with methicillin, some bacteria began to synthesize cell walls using a protein that was not affected by methicillin. these bacteria survived the methicillin treatments and reproduced at higher rates than did other individuals. over time, these resistant individuals became increasingly common. in response to treatment of staphylococcus aureus infections with methicillin, bacterial populations gradually began to synthesize cell walls using a protein that was not affected by methicillin.
