The Ames mayeso ndi wamba ntchito njira yogwiritsira ntchito mabakiteriya mayeso ngati mankhwala enaake angayambitse masinthidwe mu DNA ya mayeso zamoyo. Ndi bioloji kuyesa ndizo mwamalamulo ntchito kuyesa mphamvu ya mutagenic ya mankhwala ophatikizika.

Dziwaninso kuti mayeso a Ames ndi chiyani ndipo amagwira ntchito bwanji?

The Ames mayeso ndi njira yogwiritsidwa ntchito kwambiri yomwe imagwiritsa ntchito mabakiteriya mayeso kaya mankhwala opatsidwa angayambitse masinthidwe mu DNA ya mayeso zamoyo. Mwamwayi, ndi biological kuyesa kuyesa mphamvu ya mutagenic ya mankhwala.

Momwemonso, cholinga cha mayeso a Ames ndi chiyani? The Ames mayeso amazindikira ngati mankhwala opatsidwa angayambitse kusintha kwa mabakiteriya ake.

Pankhani iyi, cholinga cha ma enzymes a chiwindi mu mayeso a Ames ndi chiyani?

The Ames Test amaphatikiza kusinthika kwa bakiteriya kuyesa ndi kayeseleledwe ka kagayidwe ka mammalian kuti apange tcheru kwambiri mayeso kwa mankhwala a mutagenic m'chilengedwe. Khoswe chiwindi homogenate imakonzedwa kuti ipange chotsitsa cha metabolically active (S9).

Kodi ma coloni obwerera ndi chiyani?

Ngati mabakiteriya amodzi kapena angapo asinthidwa kukhala prototrophic state, komabe, zake koloni zidzapitirira kukula ndipo zidzaonekera ndi maso. Kenako amatchedwa a koloni yobwerera. Chikhalidwe chokulirapo chikuwoneka ngati chikhalidwe chowonetsera kusintha kwambuyo.
