What are disadvantages of Recombinant DNA Technology?
Recombinant DNA is DNA that have had insertion points made by enzymes called DNA ligases and restrction enzymes. An example of a disadvantage of recombinant DNA technology is the huge risks associated with genetically modified foods that could have unpredictable effects on our health and the environment. ChaCha on!As with all genetic engineering, the major concern is the unpredictability of long-term consequences.
The technologies available for genetic engineering are not yet developed enough to modify DNA of a living organism specifically and reliably. Usually, some genetic changes are introduced unintentionally and these can cause severe problems for the organism.
Let us assume the technology was perfected and human DNA could be reliably altered for living human beings. There are still two major problems:
First, genetically engineered changes are always set for the entire lifetime of an organism. The changes are introduced just after an egg is fertilised, so that all cells resulting from the egg's cell division will also carry the modifications. Once the egg has divided, genetic modification becomes much more difficult or even impossible. This means that any unexpected consequences of a modification cannot be corrected and the organism then has to live with those consequences.
The second problem is the concern of what would be done with this technology. The intentions behind its develoment are almost always to improve medicine for treating genetic diseases, but the ability to modify DNA could be abused for unethical purposes once it is available.
Some disadvantages of DNA recombinant technology include:
- huge consumer resistance to Genetically modified food (i.e. many people do not like food that has been 'tampered with' genetically
- Genetic variety reduced (e.g. in crops, the amount of alleles is drastically reduced)
- Potential for interbreeding between wild and transgenic organisms
- Ethical considerations: e.g. animal rights/welfare, collecting DNA samples
Borders on the issue of ethics, Unexpected or undetected mutations can take place, It's costly, Introducing genetically modified genes may have an irreversible effect with unknown consequences.
genetic engineering can stop the growth of DNA which is needed to produce more genes to pass on to offspring.

A restriction enzyme, also called a restriction endonuclease, is needed to cleave vector DNA when using recombinant DNA technology.
Recently scientists have been able to create synthetic DNA, and this means they can make a bacteria cell do certain things, e.g take in carbon dioxide from atmosphere and cure diseases.
no profit to answer
when we are using some technology it willhave some kind of disadvantages so rectify that we search for new technology

An advantage of technology is the fact that many people can use it easily. One disadvantage is the fact that some technology that is helpful is expensive.
