The pitch of the B-DNA is

Question

The pitch of the B-DNA is (A) 36 mathringA (B) 3.4 mathringA (C) 34 mathringA (D) 3.6 mathringA

Tardigrade Admin · Accepted Answer

In B-DNA, one turn of helical strand has 10 nucleotides. The base pairs of DNA are stacked 3.4 mathringA part. ∴ Pitch of the DNA =3.4 mathringA × 10=34 mathringA

Q. The pitch of the B-DNA is

$36 \overset{˚}{A}$

$3.4 \overset{˚}{A}$

$34 \overset{˚}{A}$

$3.6 \overset{˚}{A}$

In B-DNA, one turn of helical strand has $10$ nucleotides.
The base pairs of DNA are stacked $3.4 \overset{˚}{A}$ part.
$∴$ Pitch of the DNA $= 3.4 \overset{˚}{A} \times 10 = 34 \overset{˚}{A}$

Q. The pitch of the B-DNA is

36A˚

3.4A˚

34A˚

3.6A˚

In B-DNA, one turn of helical strand has 10 nucleotides. The base pairs of DNA are stacked 3.4A˚ part. ∴ Pitch of the DNA =3.4A˚×10=34A˚
