Genetic engineering is the concept and practice of reorganizing or restructuring the genetic structure of a chromosome, at molecular levels, and often includes genetic manipulation like in gene cloning, gene transfer or therapy. In 1973 genetic engineering took a leap forward…
Almost all genetic engineering processes aim to make life easier, for those who suffer from genetic disorders. Some processes like genetic screening, even aim to recognize or diagnose disorders at an early stage, and even before the problems actually start showing their symptoms. Such early diagnoses would definitely help to prevent the disorder from reaching serious and debilitating conditions, thus saving lives. Gene therapy promises to replace the defective genes by normal and functional genes, thus bringing in a new hope for patients with no treatments available as such. However there is a dark side to all these bright envisions. Genes or chromosomes form the basic components of life, and scientists who work on genetic engineering are working with ‘life’ itself. Cloning which can create new organisms from a single DNA fragment makes a scientist equivalent to almost ‘God’, where the former is also creating new lives. It is here where one needs to have supreme control and not cross certain limits, or else what we saw in the science thriller movie’ “Boys from Brazil’, where the Nazis procreate 94 clones of Hitler to bring back the ‘Third Reich’, would not remain a science fiction anymore, and may become a distinct reality, if we are not careful.
The reproduction of humans and animals using artificial methods IVF, AI and embryo transplantation - Artificial insemination (AI), as defined by Nabor-Neri “artificial insemination is an impregnation not by means of natural intercourse, but by means of mechanical, artificial aids such as injecting the semen or sperm directly in to the female sex organ by the use of a tuberculin syringe” (Nabor-Nery, 81). This process is used as assisted reproductive techniques to impregnate the female partner where there is a case of fertility problems of the male partner, and also in ...

Generally, if there is a heritable factor, then the cancer will occur earlier in life than a sporadic condition. However, it is important to note that people do not inherit breast cancer, but rather an increased likelihood of having the disease . Around 20 – 30% of women who have breast cancer have the disease occurring within their family, however there are also many environmental risk factors, such as use of alcohol or exposure to radiation .
This is a discussion on the issues dealing with behaviour genetics and ethics that has been a major part of the news in recent months. Several areas of the arguments would deal with the genetics and behavioural changes, whether behaviour is species specific, whether behavioural changes relate to changes in biological structures and processes and the evolutionary history or DNA sequencing that are related to behavioural genetics.
In order for such a procedure to be done, two RAD51 targeting constructs that contained either neomycin or blasticidin first had to be prepared. Once these targeting constructs were prepared, the RAD51 neo constructs were transpected into DT40 cells, and heterozygous clones were isolated for the RAD51 gene.
