RECOMBINANT-DNA

Genetic Engineering

• Direct manipulation of an organism’s genes using biotechnology.

• Covers different kind of technologies used to alter the genomes that includes the insertion of genes from other individual either the same or from different species that aims to produce or improve products.

• Process of changing the DNA in living organisms to create something new.

• It involves artificial manipulation, modification, and recombination of DNA or nucleic acid molecules to modify an organism or population of organisms.

Recombinant DNA Technology

• Involves using enzymes and various laboratory techniques to manipulate and isolate DNA segments of interests.

• This method can be used to combine (or splice) DNA from different species or to create genes with new functions.

Steps in Recombinant DNA:

• Identify the DNA from the organism

• Remove the gene from the rest of the DNA

• Insert the new gene to an existing organism’s DNA.

Artificial Selection

• Done to indirectly manipulate genes focusing on the physical traits among organisms.

• Breeders choose which organism to mate and produce offspring with desirable traits.

• They maintain this procedure without control of what genes can be passed.

Selective Breeding

• Process when animals with desired characteristics are mated to produce offspring with those desired traits such as Angus cows are bred to increase more meat.

Inbreeding

• Technique of breeding organisms that are genetically similar to maintain desired traits found in the pure dog breeds.

Hybridization

• When two individuals with unlike characteristics are crossed to produce the best in both organisms like the disease resistant potato called Burbank potato.
