Original context

// =============================================================================
// SUPERCOILING
// =============================================================================

// Supercoiling handles DNA supercoiling calculations
type Supercoiling struct{}

// LinkingNumber returns Lk = Tw + Wr
func (Supercoiling) LinkingNumber(twist, writhe float64) float64 {
	return twist + writhe
}

// Twist16Strands returns Tw = N/10.6 × 16
func (Supercoiling) Twist16Strands(N int) float64 {
	return (float64(N) / BasePairsPerTurn) * NumStrands
}

// RelaxedLinkingNumber returns Lk₀ = N/10.6

LinkingNumber returns Lk = Tw + Wr
