By growing the new bacterial colonies in bulk, they can collect and purify the desired protein and use it for pharmaceutical or industrial purposes. The example being colorectal cancer and high level of Fusobacterium nucleatum. The single-stranded part of any of the DNA fragments can join the single-stranded part of any other DNA fragment hence causing the ends to be sticky. REs that cut both DNA strands at positions a few bases apart from each other lead to the creation of staggered ends with exposed DNA bases (bases without complementary pairs). Other ethical concerns relate to the use of Genetic Technology in agriculture and animal husbandry. The exact DNA fragment can be designed with custom sequences. But today its application has spread a lot to biological systems and disease areas. Researchers are using these techniques to identify new genes which cause genetic disease at an astonishing rate - over 4000 diseases now have a known single genetic cause, compared to around 50 in 1990. CRISPR genome editing is another example of key technology using genomic data in crop-breeding applications. The polymerase chain reaction can distinguish well . The gene machine is the most modern technique where scientists create DNA fragments in a laboratory using computers and special devices.

Researchers have already discovered over 800 different mutations in BRCA1 alone.The DNA microarray is a tool used to determine whether the DNA from a particular individual contains a mutation in genes like BRCA1 and BRCA2. More steps are involved. This DNA change occurs after conception and is not hereditary. 22q11.2 Deletion Syndrome occurs 1 in every 3000-6000 births and is evenly distributed between male and female cases (Kraus et al. There are some implications and disadvantages that come with it. All rights reserved. 3. What is the future of Genetic Technology?
