A single base pair of DNA weighs 1.1 × 10–21 grains. How many picomoles of a plasmid vector of length 2750 bp are contained in 1 ug of purified DNA?
-
- 0.30
- 0.55
- 0.25
- 0.91
Correct Option: B
Given, weight of single base pair of DNA= 1.1 * 10–21 grains
Length of plasmid vector= 2750bp
Purified DNA= 1ug
Thus, 0.55 picomoles of a plasmid vector of length 2750bp are contained in 1ug of purified DNA.
