the most common host for genetic engineering is most probably Escherichia coli ( E.coli) it is considered the model organism for genetic engineering.

The reason being it is of shorter base pairs, presence of non- coding sequences and rapidly multipying.

Genetic engineering of any species involves directly changing the genetic code of the organism. This is done by taking out nucleotide bases out of the DNA sequence by using nuclease, then introducing the new DNA sequence into the host organism.



Genetic Engineering techniques alter the chemistry of genetic material (DNA or RNA), to introduce these into host organisms and thus change the phenotype of host organisms. It has application in medicine, research, industry and agriculture and can be used in wide range of plant, animals and micro-organisms.In medicine, genetic engineering has been used to mass produce insulin, human growth hormones.In research, organisms are genetically engineered to discover the function of certain genes.


Plasmids are typically used to introduce foreign DNA into a host cell. This can be done a multitude of ways, one of which is electroporation.



genetic engineering can increase genetic diversity of species of populations, esp. those that inhabit. (domesticated animals)increase efficiency of ecosystem services by other organisms:EX. MODIFICATION OF TREES' GENES CAN INCREASE ROOT SYSTEMS OF ORGANISMS AND REDUCE DAMAGE BY FLOOD PHENOMENON THROUGH FLOOD MITIGATION.modification of DNA structure of agricultural crops can increase growth rates & resistance to different diseases caused by pathogens and parasites, and can increase production of food sources to host the world's growing populations and reduce the usage of chemicals like fertilizers and pesticides, which can decrease the risk of inbreeding which can produce infertile youths.BASICLY, I THINK GENETIC ENGINEERING IS QUITE BENEFICIAL! :) GUESS WHO I AM! :)AnswerIf you are looking for a good answer, look for a scientist who works with it. DO NOT look through websites. people have misleading information saying anti-genetic engineering things that contradict everything that is the truth. I am fully pro-genetic engineering and I know my stuff. People who make hate-sites do not have a clue so be careful.


The four steps of genetic engineering are: Isolating Gene- isolate pieces of DNA with the desirable gene Cutting the desired gene - Removing gene from the organism. Making Recombinant DNA- placing the small pieces of DNA into a host cell. Cloning and Screening- for colonies that are producing the desired protein


GE is removing DNA from selected animals then adding new genes (which posses different traits) into the DNA itself before implanting the cell into the host


Yes viral genes redirect the genetic and metabolic activities of a host cell. This happens when a virus enters a host cell.


An embryo shares half of the genetic pattern of the mother. HOWEVER- you said HOST mother. In the case of a fertilized egg implanted in a mother that did NOT donate the egg, then there is no genetic relation between embryo and host mother.


To duplicate, viruses insert their genetic material into a host cell along with enzymes. The host cell's internal replication machinery is hijacked, and the cell begins producing the proteins to make new viruses. In genetic engineering, the viral DNA is changed (through a variety of techniques) to include the altered genetic material that is intended to change or replace pieces of the host's genome. It also usually includes a "repair protein" that keeps it from killing the host cell. Special receptors on the surface of the virus allow it to attach to the appropriate cells (for instance certain adeno-associated viruses can insert information specifically into chromosome 19), and the modified DNA is introduced via the usual method of viral reproduction. Instead of replicating new copies of the virus, the cells begin to copy the new genetic material, which then is incorporated into the host's genome.


Selective breeding cannot produce radical changes in the host organism rapidly. For example, breeding potatoes for cold resistance using selective breeding would result in incremental improvements over many generations. With genetic engineering cold resistant potatoes can be produced in only a year or two. Another good example of genetic engineering is roses. For centuries, breeders struggled to produce a blue rose. Unfortunately the rose plant is incapable of producing any kind of blue pigment. Genetic engineering added the gene for blue pigments to the rose genome, allowing breeders to explore many more rose colors than they could before.


no, very similar genetic information. as you and i dont have the same genetic information do we? same ecological niche? well sorta, i wouldnt call it an ecological niche, the factors that make the niche such as temperature, humidity, host range would be the same.


Selective breeding: the process by which humans breed animals or plants for specific genotypes and phenotypes. Cloning: the process of creating a whole population or an individual genetically identical to the host (or original) organism. Genetic engineering: the direct manipulation of an organism's genome using biotechnology to give it traits it typically wouldn't have or to take away traits it typically would have had.


It's called a parasitic relationship when one species benefits and one species is harmed. A simbiotic relationship is when both species benefit.


This is called a host cell. In the beginning, a virus will attach itself to the host cell and release its genetic material into it. This genetic material interferes with the host cell's enzymes which cause them to form parts in which will create a new virus.


The best example of this is Insulin produced in E.coli and this is carried out by recombinant DNA technology wherein the desired gene of interest in inserted into a vector system and then into host cell.


The host species of pasteurella multocida are the reservoirs of the bacteria. The host species are various animals such dogs, cats, pigs, etc.


by injecting their genetic material into the host cell causing the cell to react and sometimes causing a genetic mutation


When genetic-material-inactivating 'control substances' are located at those control sites.


Viruses are made up of proteins (capsid) and genetic material. Virus surface protein interact with its host cell receptors for the entry (1st step in infection). Viral particle can infect the host by inserting their genetic material in to the host genome. Host synthetic machinery produce viral proteins.


"Vector" is an agent that can carry a DNA fragment into a host cell. If it is used for reproducing the DNA fragment, it is called a "cloning vector". If it is used for expressing certain gene in the DNA fragment, it is called an "expression vector".
