How Sequencing Is Done

At JGI, we use whole-genome shotgun sequencing. This is a technique for determining the DNA sequence of a genome by randomly shearing the DNA, sequencing multiple fragments whose sequences overlap, and inferring the original sequence by reassembling the fragments. Three sizes of fragments are sequenced, 2-4 kb (kilobase, or 1000 bases), 8-10 kb, and 40 kb. This explanation follows the procedure for 2-4-kb fragments.

Life Science and Informatics

What is this?
is this a new industry?
or a old wine in a new bottle?

Well Life Sciences and Informatics can be anything form computational biology, all omes and omics, core bioinformatics to curation and literature mining, database creation, in the area of biology, chemistry , bio-chem space.

There are number of companies in India and bangalore is the forefront as a major bio-cluster with 20 to 30 companies in this sphere.

now how good are these companies doing?
how good are they in terms of the international markets and how profitable is their business?
what do they do?
their clients?

These are some interesting things that could be discussed in this blog page...
