Kua hurihia e te tauhohenga mekameka polymerase (PCR) te koiora ngota, ā, ka taea e ngā kaipūtaiao te whakanui ake i ngā raupapatanga DNA motuhake me te tino tika me te whai hua. Kei te ngako o te tukanga ko te huringa wera PCR, he taputapu nui e whakahaere ana i ngā huringa pāmahana e hiahiatia ana mō te whakakorenga DNA, te whakamahana, me te whakawhānui. Heoi, ko te whai huatanga o te huringa wera PCR e whakawhirinaki nui ana ki tōna whakatikatika. Ka tūhuratia e tēnei tuhinga te hiranga o te whakatikatika huringa wera PCR me tōna pānga ki ngā hua whakamātautau.
Te whakatikatika o tētahiPūhiko wera PCRMā tēnei ka whakarite kia mahi te taputapu i roto i te awhe pāmahana kua tohua, ā, kia mau tonu te tika e hiahiatia ana mō te whakanui angitu. He mea nui te whakahaere pāmahana i roto i te PCR nā te mea ko ia taahiraa o te huringa e whakawhirinaki ana ki ngā āhuatanga wera tika. Hei tauira, i te wā o te whakakorenga matū, me whakamahana ngā aho DNA ki te 94-98°C kia wehea ai. Mena he iti rawa te pāmahana, ka puta pea te whakakorenga matū kāore i oti, ka hua ake he whakanui koretake. I tetahi atu taha, ki te teitei rawa te pāmahana, ka kino pea te DNA, ngā whākōkī rānei e whakamahia ana i roto i te tauhohenga.
Hei tāpiritanga, me whai pāmahana motuhake te taahiraa whakamahana, e whakatauhia ana e te pāmahana rewa o ngā paninga e whakamahia ana. Mēnā kāore i te tika te whakatikatika o te huringa wera, ka hē pea te pāmahana whakamahana, ka hua ake he herenga kore-motuhake, he kore rānei he herenga. Ka hua ake pea tēnei i te iti o ngā hua, i te whakanui ake rānei i ngā hua kāore i te whakaarohia, ā, ka mutu, ka whakararu i te pono o te whakamātautau.
He mea nui te whakatikatika auau i ngā mīhini huringa wera PCR kia mau tonu ai te pono me te taea te whakaputa anō i ngā hua. I roto i te wā, ka rerekē pea ngā mīhini huringa wera i ō rātou tautuhinga whakatikatika nā ngā āhuatanga pēnei i te pakaru me te haehae, ngā huringa taiao, tae atu ki ngā rerekētanga o te pūtake hiko. Mā ngā tirotiro whakatikatika auau ka āwhina i te tautuhi i ēnei rerekētanga me te whakarite kei te pai te mahi a te taputapu. He mea nui rawa atu tēnei i roto i ngā taiao rangahau e tino hiahiatia ana ngā inenga tika, pēnei i ngā tātaritanga haumanu, te rangahau ira, me te tātaritanga taihara.
Haunga te whakarite i te whakahaere tika o te pāmahana, he mea nui te whakatikatika i roto i te mahi whānui o te huringa wera PCR. Ka taea e te mīhini kua whakatikatikahia pai te whakanui ake i te whai huatanga o te tukanga PCR, ā, ka piki ake te hua o te DNA ūnga. He mea nui rawa atu tēnei i roto i ngā tono he iti noa ngā rauemi tīmatanga, pērā i te tātari pūtau-kotahi, te rangahau DNA tawhito rānei. Mā te whakanui ake i te whai huatanga o te tukanga whakanui, ka taea e ngā kairangahau te whiwhi i te nui o te DNA mō ngā tono o muri mai, pērā i te raupapatanga, te tāruarua rānei.
Hei tāpiri atu ki tēnā, ko te hiranga o te whakatikatika he nui atu i te whakamātautau kotahi. I roto i ngā taiao whakahaeretia, pērā i ngā taiwhanga haumanu, me mātua whai i ngā tikanga whakahaere kounga tino pakari. Ko te whakatikatika auau i ngā mīhini huringa wera PCR he whakaritenga maha kia tutuki ai ngā paerewa ture. Ki te kore e mau tonu te whakatikatika tika, ka puta he hua hē, ka pā kino pea ki ngā whakataunga tiaki me te maimoatanga o te tūroro.
Hei whakamutunga, ko te whakatikatika oNgā huringa wera PCRhe āhuatanga taketake o te koiora ngota e kore e taea te wareware. He mea nui te whakahaere pāmahana tika mō te angitu o te PCR, ā, mā te whakatikatika auau ka whakarite kia mahi te huringa wera i roto i ngā whakaritenga e hiahiatia ana. Mā te whakarite kia waiho te whakatikatika hei kaupapa matua, ka taea e ngā kairangahau te whakapai ake i te pono me te kaha ki te whakaputa anō i ā rātou hua, ā, i te mutunga ka whakatairanga i te mara o te koiora ngota me ōna tono i roto i te rongoā, te ira tangata, me ētahi atu. I te mea kei te piki haere tonu te hiahia mō ngā tikanga ngota tika me te tika, ka nui ake te hiranga o te pupuri i tētahi huringa wera PCR kua whakatikatikaina pai.
