Genetic engineering is the process of using recombinant dna (rdna) technology to alter the genetic makeup of an organism. Traditionally, humans have manipulated genomes indirectly by controlling breeding and selecting offspring with desired traits. Genetic engineering involves the direct manipulation of one or more genes.
2 jul 2019 recently, rapidly evolved gene editing techniques make it possible for rapid and precise genetic modification for plants or algae.
Crispr gene editing is a genetic engineering technique in molecular biology by which the genomes of living organisms may be modified. It is based on a simplified version of the bacterial crispr.
Note that genetic engineering is an essential part of the development process. Firstly, vector viruses are stripped of any genes that might harm you and actually cause disease. Genes that cause replication are also removed, so the virus is harmless and cannot replicate.
Using recombinant dna technology to modify an organism’s dna to achieve desirable traits is called genetic engineering. Addition of foreign dna in the form of recombinant dna vectors that are generated by molecular cloning is the most common method of genetic engineering.

Genetic engineering can be defined as manipulation of an organism’s genes with the help of biotechnology. The first official genetic manipulation happened in 1972 by paul berg when he combined the dna from a monkey virus with the lambda virus. Genetic engineering is a very controversial topic in our society.
For example, you can modify a plant to need less water, but that would make it intolerant to direct sunlight (pros and cons of genetic engineering, 2014). Unfavorable diversity genetically engineered species that reach the wild can have a negative impact on the domestic species.
