Polymerase Chain Reaction (PCR) has revolutionized molecular biology, but what actually fuels this powerful technique?โฃโฃ
The key reagents that make DNA amplification possible are:โฃโฃ
โฃโฃ
๐. ๐๐๐ ๐๐๐ฆ๐ฉ๐ฅ๐๐ญ๐โฃโฃ
The sample DNA that contains the target region to be amplified.โฃโฃ
โฃโฃ
๐. ๐๐ซ๐ข๐ฆ๐๐ซ๐ฌ (๐
๐จ๐ซ๐ฐ๐๐ซ๐ & ๐๐๐ฏ๐๐ซ๐ฌ๐)โฃโฃ
Short, synthetic oligonucleotides that bind to the specific target sequence and initiate replication.โฃโฃ

Building blocks (A, T, G, C) for synthesizing new DNA strands.โฃโฃ
โฃโฃ
๐. ๐๐๐ช ๐๐๐ ๐๐จ๐ฅ๐ฒ๐ฆ๐๐ซ๐๐ฌ๐โฃโฃ
A thermostable enzyme derived from Thermus aquaticus that extends primers and synthesizes DNA at high temperatures.โฃโฃ
โฃโฃ
๐. ๐๐ฎ๐๐๐๐ซ ๐๐จ๐ฅ๐ฎ๐ญ๐ข๐จ๐งโฃโฃ
Maintains optimal pH and ionic conditions necessary for enzyme activity and stability.โฃโฃ
โฃโฃ

A crucial cofactor that enhances the catalytic activity of DNA polymerase.โฃโฃ
โฃโฃ
All these components work synergistically in a thermo cycler to denature DNA, anneal primers, and extend new strands, completing cycles of exponential DNA amplification.โฃโฃ

Whether you're diagnosing disease, genotyping, cloning, or conducting forensic analysis, PCR wouldn't be possible without these fundamental reagents.โฃโฃ
