You have an E.coli strain in which the lac operon is not expressed when glucose is absent and lacto is present. You have already conducted tests with partial diploids to rule out lacl, lacO, lacZ, lacY ar lacA as the culprits, so you know that something must be wrong with the positive regulation syster Which of the following mutations could be causing this mutant phenotype? cya- where glucose cannot bind adenylate cyclase cap- where CAMP cannot bind to CAP cap- where CAP cannot bind to the CAP binding site O Mutation in the CAP binding site that prevents CAP from binding O cya- where adenylate cyclase cannot turn ATP into CAMP

Mitochondrial Mutations

A mitochondrion is a cellular organelle that serves as the site for cellular respiration and energy production (ATP or Adenosine Triphosphate). It is a double-membrane-bound organelle and is only present in eukaryotic cells.
