In the given diagram showing two helices A and B:
1. A is left handed helix and B is right handed helix
2. A is right handed helix and B is left handed helix
3. Both are right handed helices
4. Both are left handed helices
The strands of the DNA double helix are:
1. | identical | 2. | coiled around each other |
3. | parallel to each other | 4. | complementary to each other |
At each step of ascent, the helical strand of DNA turns
1. 36 degree | 2. 34 degree |
3. 20 degree | 4. 180 degree |
The pitch of DNA helix is:
1. 0.34 nm | 2. 3.4 nm |
3. 34 nm | 4. 340 nm |
