| DNA, neoplasm | DNA present in neoplastic tissue. (12 Dec 1998) |
|---|---|
| DNA, nongenetic | Through the marvellous medium of the Internet, we have discovered that DNA need not refer to deoxyribonucleic acid. Specifically, in an e-mail entitled A day in the life of a specialist registrar from Glascow, Scotland we read that in gynaecology outpatient clinic, the specialist registrar (resident in the U.S.) at 12:10 Sorted out the DNA's (did not attends). We in the U. S. Might say the no-show when a patient does not present for his/her appointment. (12 Dec 1998) |
| DNA, plant | Deoxyribonucleic acid that makes up the genetic material of plants. (12 Dec 1998) |
| DNA, protozoan | Deoxyribonucleic acid that makes up the genetic material of protozoa. (12 Dec 1998) |
| DNA, recombinant | Biologically active DNA which has been formed by the in vitro joining of segments of DNA from different sources. It includes the recombination joint or edge of a heteroduplex region where two recombining DNA molecules are connected. (12 Dec 1998) |
| DNA, repetitive | DNA sequences that are repeated in the genome. (12 Dec 1998) |
| DNA, ribosomal | DNA sequences encoding ribosomal RNA. These sequences regulate amplification and transcription initiation and contain transcribed and nontranscribed spacer segments. (12 Dec 1998) |
| DNA, satellite | DNA that contains many tandem (not inverted) repeats of a short basic repeating unit. Satellite DNA is located at very specific spots in the genome (on chromosomes 1, 9, 16 and the Y chromosome, the tiny short arms of chromosomes 13-15 and 21 and 22, and near the centromeres of chromosomes). (12 Dec 1998) |
| DNA, single-stranded | A single chain of deoxyribonucleotides that occurs in some bacteria and viruses. It usually exists as a covalently closed circle. (12 Dec 1998) |
| DNA, superhelical | Circular duplex DNA isolated from viruses, bacteria and mitochondria in supercoiled or supertwisted form. This superhelical DNA is endowed with free energy. During transcription, the magnitude of RNA initiation is proportional to the DNA superhelicity. (12 Dec 1998) |
| DNA, viral | Deoxyribonucleic acid that makes up the genetic material of viruses. (12 Dec 1998) |
| DNA-(apurinic or apyrimidinic site) lyase | <enzyme> Formerly EC 3.1.25.2 Registry number: EC 4.2.99.18 Synonym: endodeoxyribonuclease (apurinic or apyrimidinic), apurinic endonuclease, apurinic DNA endonuclease, purine insertase, endonuclease iv, DNA repair endonuclease, endonuclease vi, endonuclease iv, E coli, bap1, bovine ap endonuclease I, nfo gene product, apci, apcii, apciii, ap lyase, ap endonuclease, hap1 DNA repair enzyme, apurine-apyrimidine endonuclease (26 Jun 1999) |
| DNA-activated protein kinase | <enzyme> Nuclear serine-threonine protein kinase that phosphorylates DNA-binding proteins; may function in cell homeostasis Registry number: EC 2.7.10.- Synonym: DNA-pk, DNA-dependent protein serine-threonine kinase, DNA-dependent protein kinase, scid gene product, xrcc7 gene product (26 Jun 1999) |
| DNA-binding protein, cyclic AMP-responsive | A protein that has been shown to function as a calcium regulated transcription factor as well as a substrate for depolarisation-activated calcium calmodulin-dependent protein kinases I and II. This protein functions to integrate both calcium and camp signals. (12 Dec 1998) |
| DNA-binding proteins | Proteins which bind to DNA. The family includes proteins which bind to both double- and single-stranded DNA and also includes specific DNA binding proteins in serum which can be used as markers for malignant diseases. (12 Dec 1998) |
