BIOXII06: MOLECULAR BASIS OF INHERITANCE

343081 Chargaff's rule is applicable to:

1 Double stranded DNA

2 Single stranded RNA

3 Single stranded DNA

4 Single stranded DNA and RNA

343082 $1.7 m$ double helical DNA will have base pairs_____

1

3.4 \times 10^{9}

2

1.7 \times 10^{9}

3

1.7 \times 10^{5}

4

5 \times 10^{9}

Explanation:

The length between two base pair is $0.34 nm$ . Total length of double helix DNA = total number of base pairs * distance between two bpHere, total no. of base pair is unknown, let us assume it to be $y . 1 .7 m = Y \times 0 .34 \times 1 0^{6}$
$Y = 0 .34 \times 1 0^{6} / 1 .7 = 5 \times 1 0^{9}$
