Question : Calculate the length of the DNA thread, if the DNA has 4.7xx10^(-9) base pairs. Length of the DNA = Total number of base pairs xx distance between two consecutivebase pairs.

Answer»

Solution :Distance between TWO consecutive base pairs `= 0.34 XX 10^(-9)`
Total number of the pairs `= 4.7 xx 10^(-9)`
`therefore`LENGHT of the DNA `= 4.7 xx 10^(-9) xx 0.34xx 10^(-9)`= 1.59 m (approximately )
