1.	Question : A ds DNA is 100 kbp long. The number of nucleotides, number of complete turns in the molecule and the length of the DNA molecule will be:-
Answer» `1.2xx10^(5),20000,3.4xx10^(4)nm` `2xx10^(5),10000,3.4xx10^(4)nm` `2xx10^(5),10000,0.34xx10^(4)nm` `2xx10^(5),100000,3.4xx10^(4)nm` Solution :(i) 100 kbp=100000 bp or 200000 bases (ii) 10 bp forms 1 TURN of DNA & therefore, 100000 bp form 10000 TURNS. (III) 10 bp are equal to 34Å and therefore, 100000 bp are equal to `3.4xx10^(4)nm` (or `3.4xx10^(5)`Å or `3.4xx10^(-5)m`)
