Question

A given double stranded DNA molecule is 1,00,000 base pairs long. The length of this DNA molecule will be (A) 10,000 nm (B) 3.4 × 104 nm (C) 104 nm (D) 2,00, 000 nm

Tardigrade Admin · Accepted Answer

The length of this DNA molecule will be 3.4 × 104 nm because one complete spiral of the helix is 3.4nm ( 34A° ) long and has 10 base pairs.

Q. A given double stranded DNA molecule is 1,00,000 base pairs long. The length of this DNA molecule will be

10,000 nm

$3.4 \times 1 0^{4}$ nm

$1 0^{4}$ nm

2,00, 000 nm

The length of this DNA molecule will be $3.4 \times 1 0^{4}$ nm because one complete spiral of the helix is 3.4nm ( $34 A^{\circ}$ ) long and has 10 base pairs.

Q. A given double stranded DNA molecule is 1,00,000 base pairs long. The length of this DNA molecule will be

10,000 nm

3.4×104 nm

104 nm

2,00, 000 nm

The length of this DNA molecule will be 3.4×104 nm because one complete spiral of the helix is 3.4nm ( 34A∘ ) long and has 10 base pairs.

$3.4 \times 1 0^{4}$ nm

$1 0^{4}$ nm

The length of this DNA molecule will be $3.4 \times 1 0^{4}$ nm because one complete spiral of the helix is 3.4nm ( $34 A^{\circ}$ ) long and has 10 base pairs.
