Today, our understanding of DNA enables us to do unimaginable things‐ Genetically altered children resulting from US – DNA research and experiments. Personal DNA SequencingIn the future, personal DNA sequencing will become even more affordable and easy to check for any genetic abnormalities.
DNA is the substance in booming field of genomic research. The discovery of ribozymes (an RNA molecule capable of acting as an enzyme) has profoundly altered our view of how life might have evolved. We can now imagine that there was a primitive form of life based entirely on RNA.
In this world, RNA would have functioned as the genetic material and as the enzymatic machines. This RNA world would have preceded life as we know it today, in which information transfer is based on DNA, RNA, and protein. Research has also shown that the instructions stored within DNA are "read" in two steps: transcription and translation.
Today, our understanding of DNA enables us to do previously unimaginable things. We can genetically modify organisms by manipulating their DNA – a controversial ability that was anticipated very early on. We can use DNA samples left behind at crime scenes to identify criminals. Another recent development, the Human Genome Project, attempted to sequence all the DNA in the human cell. The project was completed in 2003.
Today, a vast database of sequenced genomes exists (from animals, bacteria, fungi, and more) and allows scientists to quickly compare various species, extract important information (such as genetic relatedness), and learn about mutations and diseases. We can also pay to have your own DNA sequenced, which can give you some idea of the diseases you are genetically predisposed to, inform you about your genetic and ancestral history, and more.
Personal DNA sequencing in future!
In the future, personal DNA sequencing will become even more affordable and easy, though whether it becomes widespread remains to be seen.
Recombinant DNA (sometimes called synthetic biology) refers to the manipulation or creation of DNA sequences. It first came into practice in the 1970s and is a rapidly expanding field. Recombinant DNA has immense potential and could be used to treat genetic diseases and deficiencies.
