This will include basic safety precautions, handling of micropipettes and safe disposal of laboratory wastes. To know more about how to handle micropipettes, watch this video.
In order to identify organisms, or extracting the genes of interest, the first step typically is to extract all the DNA from the given cells/tissues.
Once the DNA has been extracted, one needs to confirm whether the extraction has happened properly or not. For this, one needs to perform the technique of gel electrophoresis. To know more about gel electrophoresis, you can either read this article or watch this video.
Once the entire DNA has been isolated, often a specific gene of interest needs to be isolated form it. The simplest way to do this is through the technique of Polymerase Chain Reaction (PCR) which amplifies the number of copies of the gene of interest. To know more about PCR, you can either read this article or watch this video.
Once the gene of interest is obtained and sequenced, it is compared to the known gene sequences using the bioinformatics technique of BLAST. To know more about BLAST, you can either read this article or watch this video.
