DNA recognition by nuclear receptors

Essays in Biochemistry, 2004
The nuclear receptors constitute a large family of ligand-inducible transcription factors. The control of many genetic pathways requires the assembly of these nuclear receptors in defined transcription-activating complexes within control regions of ligand-responsive genes.

NUCLEAR DNA‐DEPENDENT DNA POLYMERASES IN HUMAN BRAIN

Journal of Neurochemistry, 1977
Abstract—DNA‐dependent DNA polymerases were partially purified from nuclei of cells from the occipital lobe of human brain. The purification procedure included successive DEAE‐cellulose and phosphocellulose column chromatography, gel filtration and sucrose density gradient centrifugation steps. Four enzymes corresponding to DNA polymerases‐α, β, γ, and

Distribution of nuclear mitochondrial DNA in cattle nuclear genome

Journal of Animal Breeding and Genetics, 2007
SummaryThe nuclear mitochondrial pseudogenes (numts), originated from mtDNA insertions into the nuclear genome, have been detected to exist in many species. However, the distribution of numts in cattle nuclear genome yet has not been fully reported. By referring to the whole cattle mtDNA sequence and to the recently released cattle nuclear genome by ...

Nuclear DNA variation in Eu-Sorghums

Chromosoma, 1971
There are significant differences in nuclear DNA amount between Eu-Sorghum species. The DNA variation is considerable. For example Sorghum durra has 63 per cent more DNA than Sorghum roxburghii. Increase in nuclear DNA is accompanied by increase in the mass of the nucleolus and of non-nucleolar material including the chromosomes.

The nuclear DNA content of lampreys

Experientia, 1975
Nous avons trouve que le contenu en ADN nucleaire varie peu chez les lamproies. Dans les 3 familles principales ce contenu represente en moyenne le 40% de celui de l'homme. Il existe une correlation entre le contenu en ADN et le caryotype dans presque tous les genres.

Nuclear DNA density of parathyroid lesions

Pathology - Research and Practice, 1992
Nuclear DNA density analysis was carried out on six normal control human parathyroid glands and forty-six pathological lesions of human parathyroid tissue. The pathological glands had originally been classified as twenty hyperplasias, twenty-one adenomas, and five carcinomas in accordance with clinical-pathological information.

DNA replication and the nuclear envelope

Biochemical and Biophysical Research Communications, 1973
Abstract Upon isolation of the nuclear membrane from cultured mouse leukemia L5178Y cells, approximately 1% of the total nuclear DNA was found to be attached to this structure. After pulse labeling of DNA and isolation of the nuclear membrane, the ratio of labeled DNA in the membrane fraction and in the rest of chromatin was compared.

Organization of Nuclear DNA

1988
The nucleus of a higher plant cell may contain 1 m or more of DNA at a concentration of approximately 100 mg. ml−1. Here resides the majority of the genetic information that specifies the growth, form, and developmental pattern of the organism. If we are to unravel the complex processes by which plant growth and development are controlled, we need to ...

Is “I-DNA” derived from Nuclear DNA ?

Nature, 1970
On the basis of double radioactive labelling and buoyant density studies, it is concluded that “I-DNA” is not a separate entity from nuclear DNA but may be an artefact derived from it.

Nuclear Import of DNA

2007
Although the nuclear import of DNA may not be a normal event in the cell, mechanisms do exist for its transport. Some of these have evolved over a billion years, as viruses and other pathogens have perfected ways to invade the host, while others appear to be fortuitous piracy, as in the case of the SV40 enhancer which binds to proteins on their way to ...
