When ds DNA has 110 nucleotides, the angle of divergence of last incomplete coil = ?Can I know the procedure?

In between Each nucleotide there is an angle of rotation of about 36^o

Each turn of DNA contains a complete roation with 10bases x 36^o=360^o

So from the Question A DNA molecule has 110 nucleotides.
For 110 nucleotides the total turns are 110/10 nucleotides forming one turn=11 turns

So i the calculation based on the numberof bases and turns in it.
Look the image for angle of rotation
