PCR (पीसीआर) के दौरान, प्राइमर _______ चरण में डीएनए स्ट्रैंड से जुड़ते हैं।
Show Hint
PCR में Taq polymerase extension step में कार्य करता है।
Updated On: Jun 22, 2026
- तापानुशीलन (Annealing)
- लाइगेशन (Ligation)
- विकृतिकरण (Denaturation)
- प्रसार (Extension)
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
पद 1: प्रश्न को समझना
हमें PCR cycle का वह चरण बताना है जहाँ primers DNA से bind करते हैं।
पद 2: मुख्य सूत्र या दृष्टिकोण
PCR steps: \[ Denaturation \rightarrow Annealing \rightarrow Extension \] पद 3: विस्तृत व्याख्या
Annealing stage में temperature कम किया जाता है ताकि primers template strand से जुड़ सकें।
पद 4: अंतिम उत्तर
अतः सही विकल्प (A) है।
