Termal \u00c7evrim Cihazlar\u0131 PCR Nas\u0131l Ger\u00e7ekle\u015ftirir?<\/h2>\n

Termal \u00e7evrim cihazlar\u0131, Polimeraz Zincir Reaksiyonu (PCR) i\u015flemi s\u0131ras\u0131nda s\u0131cakl\u0131klar\u0131 hassas bir \u015fekilde kontrol eden cihazlard\u0131r. PCR, DNA’n\u0131n belirli bir b\u00f6lgesini \u00e7o\u011faltmak i\u00e7in kullan\u0131lan bir tekniktir. Bu s\u00fcre\u00e7te DNA’n\u0131n denat\u00fcrasyonu, pimerlerin ba\u011flanmas\u0131 ve uzamas\u0131 gibi a\u015famalar yer al\u0131r. Termal \u00e7evrim cihazlar\u0131, bu a\u015famalar\u0131n her biri i\u00e7in gerekli olan s\u0131cakl\u0131k de\u011fi\u015fimlerini otomatik olarak ger\u00e7ekle\u015ftirir.<\/p>\n

PCR A\u015famalar\u0131<\/h2>\n
    \n
  1. Denat\u00fcrasyon<\/li>\n
  2. Ba\u011flanma (Annealing)<\/li>\n
  3. Uzama (Extension)<\/li>\n<\/ol>\n

    Denat\u00fcrasyon<\/h2>\n

    Bu a\u015fama, \u00e7ift sarmal DNA’n\u0131n tek sarmallara ayr\u0131lmas\u0131 i\u00e7in kullan\u0131lan y\u00fcksek s\u0131cakl\u0131k a\u015famas\u0131d\u0131r. S\u0131cakl\u0131k genellikle 94-98 \u00b0C aras\u0131nda tutulur ve bu s\u0131cakl\u0131kta DNA \u00e7ift sarmal\u0131, hidrojen ba\u011flar\u0131 k\u0131r\u0131larak tek sarmallara ayr\u0131l\u0131r.<\/p>\n

    Ba\u011flanma (Annealing)<\/h2>\n

    Denat\u00fcrasyon a\u015famas\u0131ndan sonra s\u0131cakl\u0131k, pimerlerin (k\u0131sa DNA segmentleri) hedef DNA dizilerine ba\u011flanmas\u0131 i\u00e7in d\u00fc\u015f\u00fcr\u00fcl\u00fcr. Bu s\u0131cakl\u0131k genellikle 50-65 \u00b0C aras\u0131nda olup, pimerlerin spesifik baz dizilerine ba\u011flanmas\u0131n\u0131 sa\u011flar.<\/p>\n

    Uzama (Extension)<\/h2>\n

    Son a\u015fama olan uzama a\u015famas\u0131nda, DNA polimeraz enzimi pimerlerin ba\u011fl\u0131 oldu\u011fu yerden yeni DNA zincirini sentezler. Bu i\u015flem genellikle 72 \u00b0C s\u0131cakl\u0131kta ger\u00e7ekle\u015fir ve kullan\u0131larak bir\u00e7ok yeni DNA kopyas\u0131 olu\u015fturulur.<\/p>\n

    Termal \u00c7evrim Protokol\u00fc<\/h2>\n

    PCR s\u00fcreci, yukar\u0131daki \u00fc\u00e7 a\u015faman\u0131n belirli bir say\u0131da (genellikle 20-40 d\u00f6ng\u00fc) tekrar edilmesiyle ger\u00e7ekle\u015ftirilir. Her d\u00f6ng\u00fcde DNA miktar\u0131 eksponensiyel olarak artar, bu da ba\u015flang\u0131\u00e7taki az miktardaki DNA’n\u0131n b\u00fcy\u00fck miktarlara ula\u015fmas\u0131n\u0131 sa\u011flar.<\/p>\n

      \n
    1. Denat\u00fcrasyon: 94-98 \u00b0C, 20-30 saniye<\/li>\n
    2. Ba\u011flanma: 50-65 \u00b0C, 20-40 saniye<\/li>\n
    3. Uzama: 72 \u00b0C, 1-2 dakika<\/li>\n
    4. D\u00f6ng\u00fc Say\u0131s\u0131: 20-40<\/li>\n<\/ol>\n
