| herpes simplex virus 1 helicase-primase | <enzyme> Complex of three herpes-encoded gene products (ul52, ul5, and ul8) in addition to helicase activity, contains a tightly associated complex that may prime lagging strand synthesis as it unwinds DNA at the viral replication fork Registry number: EC 3.1.- Synonym: hsv-1 helicase-primase, ul5 protein, hsv helicase-primase complex, ul52 protein, ul8 protein (26 Jun 1999) |

| Hogness box | <molecular biology> A consensus sequence found in the promoter region of most genes transcribed by eukaryotic RNA polymerase II. Found about 25 nucleotides before the site of initiation of transcription and has the consensus sequence: 5' TATAAAA 3'. This sequence seems to be important in determining accurately the position at which transcription is initiated. (18 Nov 1997) |
| Pu box | <molecular biology> Purine rich sequence recognised by the product of the Sp 1 oncogene. (18 Nov 1997) |
| snuff-box | See: anatomical snuffbox. (05 Mar 2000) |
| DnaB helicase | <enzyme> Dnac delivers the dnab helicase from a dnab.dnac complex to the future replication fork; isolated from E coli Registry number: EC 3.1.- (26 Jun 1999) |
| DNA delta-helicase | <enzyme> From foetal calf thymus; partially copurifies with DNA polymerase delta; also has DNA-dependent atpase activity Registry number: EC 3.6.1.- (26 Jun 1999) |
| DNA helicase | <enzyme, molecular biology> A prokaryote enzyme that uses the hydrolysis of ATP to unwind the DNA helix at the replication fork, to allow the resulting single strands to be copied. Two molecules of ATP are required for each nucleotide pair of the duplex. (18 Nov 1997) |
| TATA box | <molecular biology> A consensus sequence found in the promoter region of most genes transcribed by eukaryotic RNA polymerase II. Found about 25 nucleotides before the site of initiation of transcription and has the consensus sequence: 5' TATAAAA 3'. This sequence seems to be important in determining accurately the position at which transcription is initiated. (18 Nov 1997) |
| 89B helicase | <enzyme> Snf2-like protein that binds to multiple sites on polytene chromosomes; isolated from drosophila melanogaster; partial Registry number: EC 5.99.- (26 Jun 1999) |
| alveolar dead space | The difference between physiologic dead space and anatomical dead space; it represents that part of the physiologic dead space resulting from ventilation of relatively underperfused or nonperfused alveoli; it differs specifically in being placed so as to fill and empty in parallel with functional alveoli, rather than being interposed in the conducting tubes between functional alveoli and the external environment. (05 Mar 2000) |
| anatomical dead space | The volume of the conducting airways from the external environment (at the nose and mouth) down to the level at which inspired gas exchanges oxygen and carbon dioxide with pulmonary capillary blood; formerly presumed to extend down to the beginning of alveolar epithelium in the respiratory bronchioles, but more recent evidence indicates that effective gas exchange extends some distance up the thicker-walled conducting airways because of rapid longitudinal mixing. Compare: alveolar dead space, physiologic dead space. Synonym: anatomical airway. (05 Mar 2000) |
| respiratory dead space | That portion of the respiratory tract, from the nose and mouth to the terminal bronchioles, in which exchange of oxygen and carbon dioxide does not occur (anatomical dead space), together with the space in alveoli occupied by air that does not participate in oxygen-carbon dioxide exchange (physiologic dead space). It reflects the nonuniformity of ventilation and perfusion in the lung. (12 Dec 1998) |
| physiologic dead space | The sum of anatomic and alveolar dead space; the dead space calculated when the carbon dioxide pressure in systemic arterial blood is used instead of that of alveolar gas in Bohr's equation; it is a virtual or apparent volume that takes into account the impairment of gas exchange because of uneven distributions of lung ventilation and perfusion.

| dead | 1. Deprived of life; opposed to alive and living; reduced to that state of a being in which the organs of motion and life have irrevocably ceased to perform their functions; as, a dead tree; a dead man.

Destitute of life; inanimate; as, dead matter. 3. Resembling death in appearance or quality; without show of life; deathlike; as, a dead sleep. 4. Still as death; motionless; inactive; useless; as, dead calm; a dead load or weight. 5. So constructed as not to transmit sound; soundless; as, a dead floor. 6. Unproductive; bringing no gain; unprofitable; as, dead capital; dead stock in trade. 7. Lacking spirit; dull; lusterless; cheerless; as, dead eye; dead fire; dead colour, etc. 8.

"I had them a dead bargain." (Goldsmith) 10. Bringing death; deadly. 11. Wanting in religious spirit and vitality; as, dead faith; dead works. "Dead in trespasses." 12. Flat; without gloss; said of painting which has been applied purposely to have this effect. Not brilliant; not rich; thus, brown is a dead colour, as compared with crimson. 13. Cut off from the rights of a citizen; deprived of the power of enjoying the rights of property; as, one banished or becoming a monk is civilly dead. 14. <machinery> Not imparting motion or power; as, the dead spindle of a lathe, etc. See Spindle. Dead ahead, a wind directly ahead, or opposed to the ship's course. To be dead, to die. "I deme thee, thou must algate be dead." (Chaucer) Synonym: Inanimate, deceased, extinct. See Lifeless. Origin: OE. Ded, dead, deed, AS. Dead; akin to OS. Dd, D. Dood, G. Todt, tot, Icel. Daur, Sw. & Dan. Dod, Goth. Daubs; prop. P. P. Of an old verb meaning to die. See Die, and cf. Death.
