Vedclass · Answer

(C) In the $B-DNA$ model proposed by Watson and Crick,the structure is a double helix. $1$. The length of one full turn of the $DNA$ helix is $34\ \mathring{A}$ (or $3.4\ nm$). $2$. The distance between the two polynucleotide strands (the diameter of the helix) is $20\ \mathring{A}$ (or $2.0\ nm$). Therefore,the correct values are $34\ \mathring{A}$ and $20\ \mathring{A}$.

What are the length of one full turn of the $DNA$ helix and the distance between the two strands (polynucleotides)?
