In the double helix modle of DNA , how far is each base pair from the next base pairA. 3.4 nmB. 0.34 nmC. 20 nmD. 34 nm |

Answer» Correct Answer - B The two chains are coiled in a right-handed fashion. The pitch of the helix is 3.4 nm (a nanometre is one billionth of a metre, that is `10^(-9)` m) and there are roughly 10 bp in each turn. Consequently, the distance between a bp in a helix is approximately equal to 0.34 nm. |
