what does the signal joint do ?

can any one explain what he mean by saying at 18:10 that the one helical turn (12 ) and the two helical turn make heptomer and the nanomer facing the same direction on the dna double helix?

[@JABDUDE]

As you move up or down the DNA the double helix is rotating around. Think of going up a spiral staircase to be facing the same direction as 9 steps previous or ahead.

I have a question. Does the heavy chain have more diversity than light chain? I thought it's becuase there is a D(diversity) segment in heavy chain
