Context – Most States ‘still lax in Covid genomic analysis’.
- Genome sequencing is figuring out theorder of DNA nucleotides, or bases, in a genome—the order of Adenine, Cytosine, Guanines, and Thymine that make up an organism’s DNA.
- For RNA viruses like SARS-CoV2, mutation is a normal process. It happens often when they replicate themselves in the cells. Sometimes, such mutations around the spike protein region — which the virus uses to gain entry into the human cells — can be a concern. So, there is a need to regularly monitor such mutations.
- Proper collection and genomic sequencing of these samples are important for detecting the emergence of variants that have potential to set off another wave of the pandemic.
Indian SARS-CoV2 Genomics Sequencing Consortium (INSACOG)
- This is a network of 28 national laboratories — jointly set up by the Health Ministry, the Department of Biotechnology (DBT), the Council of Scientific and Industrial Research (CSIR) and the Indian Council of Medical Research — has been sequencing samples collected from all over the country since the emergence of alpha variant (B.1.1.7) in the UK.
- INSACOG is a multi-laboratory, multi-agency, Pan-India network to monitor genomic variations in the SARS-CoV-2 by a sentinel sequencing effort
