Document Summary
One gram of dna can store 10^18 bytes of information. A digital movie was stored in the form of dna in e. coli genome. There are 6 forms of dna: a, b, c, d, t, and z. Forms abz are the physiological forms that are very relevant. Form b is commonly studied in the classroom. Form z is very rare and difficult to find as it only appears at a certain time in specific physiological conditions. As a result of the rarity of form z, sometimes it is also mistaken for form b. 2 important reasons why z form dna is hard to prove as physiologically relevant. A form dna can be present in spore for a long time, but for the z form, it is only present transiently in the cell, therefore, you need to catch it at a very specific time.
