Topoisomerase Overview & Function What is Topoisomerase?

WebSingle-strand binding proteins coat the DNA around the replication fork to prevent rewinding of the DNA. Topoisomerase binds at the region ahead of the replication fork to prevent supercoiling. Primase synthesizes RNA primers complementary to the DNA strand. DNA polymerase III starts adding nucleotides to the 3′-OH end of the primer. WebBy binding to the DNA gyrase and topoisomerase IV enzymes, which are in charge of keeping bacterial DNA in a supercoiled state, fluoroquinolones prevent the synthesis of new bacterial DNA. The antibiotic sulfonamides prevent bacteria from producing folic acid by competing with para-aminobenzoic acid (PABA) for the enzyme dihydropteroate synthase. greensboro to mt airy nc https://cvnvooner.com
