PPT-Designing the oligonucleotide primers for

PCR GENE TECHNIQUES Dr Nadal Abdulameer Ali The primers are the key to the success or failure of a PCR experiment If the primers are designed correctly the experiment results in amplification of a single DNA frag. PCR provides a forensics tool for identifying colonies. Three strains look alike!. How can you identify the strains?. Geneticists like to verify their strains’ genotypes before experiments.

RNA therapeutics as a platform is a revolutionary approach to discover new and important therapeutic agents for treating human diseases.

During PCR, two primers anneal to complementary sequences at either end of a target sequence on a piece of denatured sample DNA. . DNA polymerase. synthesizes a complementary strand of DNA from the primers, resulting in two new strands of DNA. In further cycles, the newly made DNA molecules are denatured, primers are annealed, and DNA polymerase copies the target regions, resulting in multiple copies of the original target sequence..
