Intervening sequence
Part of a gene that is initially transcribed from the DNA into the primary RNA transcript but then is excised (removed) from it when the so-called exons sequences on either side of it are spliced together.
Intervening sequences, which are also called introns, are genetic sequences that intervene between the exons. The DNA of a gene is thereby made up of an alternation of introns and exons.

- Interventional radiologist
A radiologist who uses image guidance methods to gain access to vessels and organs. Interventional radiologists can treat certain conditions through the skin (percutaneously) that might otherwise require surgery. The technology includes the use of balloons, catheters, microcatheters, stents, and therapeutic embolization (deliberately clogging up a blood vessel). The specialty of interventional radiology overlaps with […]
- Interventional radiology (IR)
Interventional radiologists employ image guidance methods to gain access to the deep interstices of most organs and organ systems. Through a galaxy of techniques, they can treat certain conditions percutaneously (through the skin) that might otherwise require surgery. (The technology includes the use of balloons, catheters, microcatheters, stents, therapeutic embolization (deliberately clogging up a blood […]

- Interventricular septum
The stout wall that separates the lower chambers (the ventricles) of the heart from one another. A hole in the interventricular septum is termed a ventricular septal defect (VSD).
