प्रश्न
A DNA model was built using the scale 2 cm : 0.0000001 mm. If the model of the DNA chain is 17 cm long, what is the length of the actual chain?
उत्तर
Let the length of the actual chain be x mm.
Therefore, `(2 cm)/(0.0000001 mm) = (17 cm)/(x mm)`
⇒ x = `(17 xx 0.0000001)/2`
= 8.5 × 0.0000001
= 0.00000085 mm
