Principles of Biotechnology And Its Applications
Genetic engineering is the system of changing the genetic cloth of an organism to introduce new developments or alter existing ones. Recombinant DNA technology is a particular method within genetic engineering that includes combining DNA from different resources to create new DNA sequences.
Key Steps Involved in Recombinant DNA Technology:
- Isolation of DNA: DNA is extracted from the organism of interest.
- Cutting DNA: Restriction enzymes are used to cut the DNA into unique fragments.
- Joining DNA: The favored DNA fragments are joined collectively the use of an enzyme referred to as DNA ligase.
- Introducing DNA into a host organism: The recombinant DNA is inserted right into a appropriate host organism, along with a bacterium or yeast.
- Cloning: The host organism multiplies, producing many copies of the recombinant DNA.
- Expression: The inserted DNA is expressed, producing the preferred product.
Cloning Vectors and Restriction Enzymes
Cloning vectors are DNA molecules which can convey foreign DNA into a bunch cellular and reflect there. Common sorts of cloning vectors include plasmids (small, circular DNA molecules observed in bacteria), bacteriophages (viruses that infect bacteria), and artificial chromosomes.
Restriction enzymes are enzymes that cut DNA at unique sequences called limit sites. These enzymes are crucial for creating DNA fragments of the desired size for recombinant DNA technology.
Polymerase Chain Reaction (PCR)
PCR is a method used to extend a particular DNA collection exponentially. It involves repeated cycles of denaturation, annealing, and extension.
Steps Involved in PCR:
- Denaturation: The DNA template is heated to split the two strands.
- Annealing: Short DNA primers bind to the complementary sequences on the template.
- Extension: A DNA polymerase enzyme extends the primers, growing new DNA strands complementary to the template.
Medicine: Biotechnology And Its Applications
Gene remedy is a clinical technique that targets to deal with genetic issues through introducing purposeful genes into cells. It includes changing faulty genes with wholesome ones or introducing new genes to provide a therapeutic advantage.
Types of Gene Remedy:
- Somatic gene therapy: Targets non-reproductive cells to treat a particular disorder within the man or woman.
- Germline gene therapy: Targets reproductive cells, doubtlessly passing the modified genes to offspring.
Genetic Diagnosis
