  • Trait

  • Any detectable phenotypic property of an organism.

  • Transcription

  • The process of copying information from DNA into new strands of messenger RNA (mRNA). The mRNA then carries this information to the cytoplasm, where it serves as the blueprint for the manufacture of a specific protein.

  • Tricuspid valve

  • The heart valve that controls blood flow from the right atrium into the right ventricle.

  • Trigger finger

  • An irritation of the digital sheath that surrounds the flexor tendons of the finger. When the tendon sheath becomes thickened or swollen, it pinches the tendon and prevents it from gliding smoothly. In some cases, the tendon catches and then suddenly rele
