- Most common DNA conformation in vivo
- Narrower, more elongated helix than A.
- Wide major groove easily accessible to proteins
- Narrow minor groove
- Favored conformation at high water concentrations (hydration of minor groove seems to favor B-form)
- Base pairs nearly perpendicular to helix axis
- Sugar pucker C2'-endo
