  1. REKAYASA GENETIKA

  2. Pengertian Teknologi rekayasa genetika merupakan transplantasi atau pencangkokan satu gen lainnya dimana dapat bersifat antar gen dan dapat pula lintas gen yang bertujuan untuk mendapatkan pruduk baru yang unggul. Rekayasa genetika juga diartikan sebagai perpindahan gen.

  3. Contoh • Polymerase chain reaction (PCR) • Insulin • Vaksin • Terapi Gen

  4. Sintesis Insulin

  5. Pengertian PCR Polymerase chain reaction (PCR) merupakan teknik yang sangat berguna dalam membuat salinan DNA. PCR memungkinkan sejumlah kecil sekuens DNA tertentu disalin (jutaan kali) untuk diperbanyak (ssehingga dapat dianalisis) atau dimodifikasi secara tertentu.

  6. 3 Tahapan PCR • Tahap peleburan (melting) atau denaturasi • Tahap penempelan atau annealing • Tahap pemanjangan atau elongasi Lepas tahap 3, siklus diulang kembali mulai tahap 1 Perkembangan pada siklus-siklus selanjutnya

  8. Pengertian Terapi Gen Terapi gen adalah teknik untuk mengoreksi gen-gen yang cacat yang bertanggung jawab terhadap suatu penyakit atau perbaikan kelainan genetik dengan memperbaiki gen.

  13. Steps • Scientists use restriction enzymes to isolate a segment of deoxyribonucleic acid (DNA) that contains a gene of interest—for example, the gene regulating insulin production. 2. A plasmid removed from a bacterium and treated with the same restriction enzyme binds with the DNA fragment to form a hybrid plasma.

  14. 3.The hybrid plasmid is re-inserted back into the bacterium, where it replicates as part of the cell’s DNA. 4. A large number of identical daughter cells (clones) can be cultured and their gene products extracted for human

  15. Restriction Enzyme

  16. Produced by some kinds of bacteria, restriction enzymes recognize specific sequences of DNA and cut the double strand where the sequence occurs. Treating the DNA of two different organisms with the same restriction enzyme produces complementary fragments, or fragments with ends that fit together. These can be combined in a hybrid DNA molecule that, if part of a living cell, expresses traits of both
