A helix is a three-dimensional spiral shape, like a corkscrew or a DNA strand. In Japanese, the most common equivalent is 螺旋 (rasen), but other terms exist for specific contexts like geometry, biology, and everyday objects.
Describing a three-dimensional curve that winds around a central axis, like a spring or a spiral staircase.
The standard word for 'helix' in most contexts, including science, mathematics, and everyday descriptions. It can also refer to a spiral in general.
DNA has a double helix structure.
The kana form of 螺旋, often used in informal writing or when the kanji are considered difficult.
An alternative kanji for 'helix', less common than 螺旋. Sometimes used in technical contexts.
Referring specifically to a mathematical helix, a curve in 3D space defined by parametric equations.
Used in geometry to describe a helix. Often combined with terms like 曲線 (curve) or 構造 (structure).
Describing the helical structure of biological molecules like DNA or alpha-helices in proteins.
The standard term in biology for a helix. Often used in compounds like 二重螺旋 (double helix) or α螺旋 (alpha helix).
Referring to the outer rim of the ear, known as the helix.
The anatomical term for the helix of the ear. Literally 'ear ring'.
Pierce the helix of the ear.
Describing a spiral scroll-like ornament, especially on Ionic capitals.
螺旋 (rasen) refers specifically to a three-dimensional spiral, like a spring or a screw thread. 渦巻き (uzumaki) is a more general term for a spiral or whirl, often two-dimensional (like a whirlpool or a spiral pattern). Use 螺旋 for helices and 渦巻き for flat spirals or whirls.
The staircase formed a perfect helix.
Climb a spiral staircase.
This spring is in a helical shape.
螺線 is an alternative notation for helix.
Derive the equation of a helical curve.
Literally 'vine-winding line', a term sometimes used in mathematics for a helix, but less common than 螺旋.
A vine-winding line is a type of helix.
The double helix of DNA was discovered in 1953.
Analyze the alpha-helix structure of the protein.
The loanword from English, used in scientific contexts, especially in biochemistry. Often seen in compounds like ダブルヘリックス (double helix).
This gene has a helix-turn-helix motif.
A more specific anatomical term combining 'auricle' and 'helix'. Used in medical contexts.
Malformation of the helix.
General word for spiral or whirl, often used for decorative spirals in architecture and art.
The volute pattern on an Ionic capital.
Literally 'helix decoration', a descriptive term for a spiral ornament.
The pillar is carved with helix decorations.
A whirlpool of water.
The loanword ヘリックス (herikkusu) is understood in scientific and technical fields, but 螺旋 is more common in general Japanese. Use ヘリックス when discussing specific scientific terms like alpha helix or helix-turn-helix motif.
The alpha helix is one of the secondary structures of proteins.
彼女は耳輪にピアスを開けた。
She got a helix piercing.
