What do you think about cloning?
Dolly the sheep, as the first mammal to be cloned from an adult cell, is by far the world's most famous clone. However, cloning has existed in nature since the dawn of life. From asexual bacteria to ‘virgin bi rths’ in aphids, clones are all around us and are fundamentally no different to other organisms. A clone has the same DNA sequence as its parent and so they are genetically identical.
Several clones had been produced in the lab before Dolly, including frogs, mice, and cows, which had all been cloned from the DNA from embryos. Dolly was remarkable in being the first mammal to be cloned from an adult cell. This was a major scientific achievement as it demonstrated that the DNA from adult cells, despite having specialised as one particular type of cell, can be used to create an entire organism
What about DNA testing? What it is used for?
Forensic DNA profiling (also called DNAtesting or DNA typing) is a technique employed by forensic scientists to identify individuals by characteristics of their DNA. DNA profiles are a small set of DNA variations that are very likely to be different in all unrelated individuals.
