Calculate the length of the DNA thread, if the DNA has `4.7 xx 10^(-9)` base pairs.
Length of the DNA = Total number of base pairs `xx` distance between two consecutive base pairs.

Explanation

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 0.34 xx 10^(-9)`= 1.59 m (approximately )
