Cloning in living things


The world is growing and people are making progress in the way they handle various issues that are connected to life and everything that surrounds it. There are a lot of things that happen in the field of Biology that are seemingly appearing as complex issues to some individuals. Cloning is one of the latest biology find outs which have shown quite a great improvement in the way scientists are working to improve their services. This article will give you the information you need concerning cloning. You will be in a position to understand everything about cloning and anything else that is related to cloning including the history of cloning.

Biologically, cloning can best be defined as the process where populations which are similar in their genetic identity reproduce similar populations after an asexual reproduction of the plants, insects, and bacteria. On biotechnology, cloning is usually referred to as the technical process where copies of the DNA are created by organisms, or cells. This term may also be used in referring to the process of creating more copies in software or the digital media.

The term cloning had its origin from J. B. S. Haldane who is a Greek individual and the term evolved from the Greek word klon. The word initially referred to the process by which the plant could be created from just plucking a twig. The spelling clon was used in horticulture until the twentieth century. The final vowel came afterwards.

Molecular Cloning

Molecular cloning is basically the process where one is able to create a multiple of molecules. The cloning process has in most cases been used in the process of amplifying the entire genes though it could be used in the amplification of the sequence of the DNA such as non-coding sequences, randomly fragmented DNAs, and promoters. In some occasions, the word cloning could be used in a misleading manner while trying to illustrate the process of chromosomal location. The localization done to the gene might at times fail to enable the amplification or the isolation of the appropriate genomic sequences. For the amplification of a certain DNA to be successful, the sequence must be linked to the origin of the replication.

Cloning can best be described as a natural form of reproduction which has facilitated the spreading of the life forms for more than 50,000 years. Cloning is the reproduction method that is mostly used by fungi, plants, and bacteria. Cloning also illustrates the actual way that the clonal colonies have been reproducing.

Are Nanobots A Threat Or A Promise Of A Better Life For All?


Imagine a world where tiny robots would not only cure all disease, but also provide all of humanity with food, as well as cleaning the depths of the ocean and clear all of the surface of the Earth of pollution.

Oil spills would be be easily dealt with and every human being on the face of the planet would be provided with enough food to enjoy a first world quality of life.

This may very well be the truth if the promise of Nanobots comes to fruition.

Nanobots are tiny, even microscopic robots that are designed in laboratories to deal with a variety of challenges that we face in the modern world.

These tiny robots, designed on the nano scale which is far smaller then most cells in our body are already under development in laboratories across the world. And their applications are as varied as the companies that are preparing to put them into production.

Imagine if you will a fleet of nanobots designed to seek out and destroy cancer cells in the human body. Injected into any site they would have a single purpose – to heal and remove the source of cancer. After they have accomplished their task they would remain – ever vigilant waiting for the sign of cancer and programmed to eliminate disease.

In the case of pollution imagine a swarm of nanobots which, sight unseen would devour oil spills and replicating using the energy they obtained from the oil that they had absorbed. Turning oil spills into harmless gas that would benefit the environment.

However there are those who believe that nanobots present as much of a threat as they do a benefit. Nanobots would be designed to be self replicating, imitating life forms, but not subject to the same limitations.

The idea of the ‘grey goo’ that could carpet our planet is part and parcel of the threat that many see inherent in the idea of nanobots.

Replicating wildly these tiny man made organisms may simply not stop in their task, and even more worryingly they might evolve to live of related substances.

If this was to be the case then a swarm of nanobots could quite easily evolve from dealing with oil spills to consuming all petrochemical products and that might spell the doom of society as it exists in the 21st century.

As with any technology nanobots have great potential, but they also have the potential to do great harm. Science may be a double edged sword – but can we afford to ignore the great potential of these tiny, yet powerful man made organisms.
