Medical Dictionary Definitions A-Z List

Medical Dictionary Definitions A - Z - «S»:

  1. Septum, ventricular Septum, ventricular
    Septum, ventricular: The wall between the two lower chambers (the right and left ventricles) of the heart....
  2. Sequela Sequela
    Sequela: A pathological condition resulting from a prior disease, injury, or attack. As for example, a sequela of polio. Verbatim from the Latin "sequela" (meaning sequel). Plural: sequelae....
  3. Sequelae Sequelae
    Sequelae: See: Sequela....
  4. Sequence tagged site (STS) Sequence tagged site (STS)
    Sequence tagged site (STS): A short (200 to 500 base pair) DNA sequence that occurs but once in the genome and whose location and base sequence are known. STSs are detectable by polymerase chain reaction (PCR), are useful for localizing and orienting the mapping and sequence data, and serve as land...
  5. Sequence, complementary Sequence, complementary
    Sequence, complementary: Nucleic acid sequence of bases that can form a double- stranded structure by matching base pairs. For example, the complementary sequence to C-A-T-G (where each letter stands for one of the bases in DNA) is G-T-A-C....
  6. Sequence, conserved Sequence, conserved
    Sequence, conserved: A base sequence in a DNA molecule (or an amino acid sequence in a protein) that has remained essentially unchanged throughout evolution....
  7. Sequence, draft DNA Sequence, draft DNA
    Sequence, draft DNA: Sequence of a DNA with less accuracy than a finished sequence. In a draft sequence, some segments are missing or are in the wrong order or are oriented incorrectly. A draft sequence is as opposed to a finished DNA sequence....
  8. Sequence, finished DNA Sequence, finished DNA
    Sequence, finished DNA: A DNA sequence in which the bases are identified to an accuracy of no more than 1 error in 10,000 and are placed in the right order and orientation along a chromosome with almost no gaps. A finished sequence is as opposed to a draft DNA sequence....
  9. Sequence, intervening Sequence, intervening
    Sequence, intervening: An intervening sequence is the part of a gene that is initially transcribed from the DNA into RNA (specifically, into the primary RNA transcript) but then is excised (removed) from it when the so-called exxon sequences on either side of it are spliced together. Intervening seq...
  10. Sequence, Klippel-Feil Sequence, Klippel-Feil
    Sequence, Klippel-Feil: See: Klippel-Feil sequence....
  11. Sequence, regulatory Sequence, regulatory
    Sequence, regulatory: A sequence of bases in DNA that controls gene expression....
  12. Sequencing Sequencing
    Sequencing: Learning the order of nucleotides (base sequences) in a DNA or RNA molecule or the order of amino acids in a protein. In the case of DNA sequencing, the precise ordering of the bases (A,T,G,C) from which the DNA is composed is determined....
  13. Sequester Sequester
    Sequester: 1. In medicine, to set apart, detach or separate a small portion of tissue from the rest. 2. In bone, for a piece of dead bone to separate from the sound bone. 3. In biochemistry, to isolate a constituent of a system by chelation or other means. From the French sequestrer, from the late...
  14. Ser Ser
    Ser: Serine. See also: Amino acid symbols....
  15. Serendipity Serendipity
    Serendipity: An accidental and fortunate discovery. Not all good medical research by any means is done by design. Some is by serendipity, pure good luck. A celebrated instance of serendipity in biomedical research took place in 1928 at St Mary's Hospital in London. While studying staphylococci (sta...
