This document summarizes a seminar presentation titled "From Magnetic Drive to Genomic Drive" presented by Ravi Vaniya and Sanat Dhobi. The presentation discusses DNA, including that it carries genetic instructions, its double helix structure, and its four nitrogen bases. Some benefits of DNA for data storage are then outlined, including its high information density, non-rewritability making it good for archiving, and ability to still be sequenced from remains thousands of years old. References concluding the document include websites for the university and Microsoft as well as research papers and Wikipedia.

3. DNA
 Deoxyribonucleic acid (DNA) is a molecule that
carries the genetic (hereditary) instructions used
in the growth, development and functioning of all
known living organism and many viruses.
 Most DNA molecules consist of
two biopolymer strands coiled around each other
to form a double helix.
 The information in DNA is stored as a code made
up of four nitrogen bases: adenine (A), guanine
(G), cytosine (C), and thymine (T).
 Nucleotide = Nitrogen base + Sugar + Phosphate.

5. Why DNA ?
1. Density of information that can be stored
- one gram of single-strand DNA could store as much as an exabyte
(1018 bytes).
2. DNA storage is not re-writable
- good for archiving records
3. Preservation
- DNA can still be sequenced from dried mummies thousands of
years old , but such sequences are rarely complete.
