3DNA misses one pair of nucleotides
« on: October 28, 2008, 01:16:53 pm »
Hi all,
I have three 20-bp identical DNAs in my pdb. 3DNA finds 59 pairs missing a second pair in one DNA. What can cause such thing?

I figured out what happened. A base of the first nucleotide was making a pair with the base of the  second nucleotide.
I fuxed this problem

Can you please make clear what was your problem and how you fixed it? I don't get it.
Thanks.

The problem was that I have 60 nucleotide pairs (double -stranded DNA), but the program found only 59 pairs. Then I realized that a base from one nucleotide makes a Watson-Crick pair with the wrong nucleotide due to low resolution and poor density. So, I restrained the bases so that they are making right pairs and now the program (3DNA) finds all 60 pairs.
