  2. Nuclear DNA - Wikipedia

    en.wikipedia.org/wiki/Nuclear_DNA

    Nuclear DNA is a nucleic acid, a polymeric biomolecule or biopolymer, found in the nucleus of eukaryotic cells.Its structure is a double helix, with two strands wound around each other, a structure first described by Francis Crick and James D. Watson (1953) using data collected by Rosalind Franklin.

  3. Nuclear power in Vietnam - Wikipedia

    en.wikipedia.org/wiki/Nuclear_power_in_Vietnam

    In June 2010, Vietnam announced that it plans to build 14 nuclear reactors at eight sites in five provinces by 2030, to satisfy at least 15 GW nuclear power (i.e. 10% share) [11] of the estimated total demand of 112 GW. An ambitious strategy to increase the nuclear share to 20-25% by 2050 has also been outlined.

  4. Westinghouse Atom Smasher - Wikipedia

    en.wikipedia.org/wiki/Westinghouse_Atom_Smasher

    The Westinghouse Atom Smasher was intended to make measurements of nuclear reactions for research in nuclear power. [8] It was the first industrial Van de Graaff generator in the world, [9] and marked the beginning of nuclear research for civilian applications. [10] [11] Built in 1937, it was a 65-foot-tall (20 m) pear-shaped tower.

  5. Nuclear organization - Wikipedia

    en.wikipedia.org/wiki/Nuclear_Organization

    There are many different levels and scales of nuclear organisation. At the smallest scale, DNA is packaged into units called nucleosomes, which compacts DNA about 7-fold. In addition, nucleosomes protect DNA from damage and carry epigenetic information. Positions of nucleosomes determine accessibility of DNA to transcription factors.

  6. Nuclear gene - Wikipedia

    en.wikipedia.org/wiki/Nuclear_gene

    Nuclear gene location. A nuclear gene is a gene that has its DNA nucleotide sequence physically situated within the cell nucleus of a eukaryotic organism. This term is employed to differentiate nuclear genes, which are located in the cell nucleus, from genes that are found in mitochondria or chloroplasts. The vast majority of genes in ...

  7. Nucleoprotein - Wikipedia

    en.wikipedia.org/wiki/Nucleoprotein

    The most widespread deoxyribonucleoproteins are nucleosomes, in which the component is nuclear DNA. The proteins combined with DNA are histones and protamines; the resulting nucleoproteins are located in chromosomes. Thus, the entire chromosome, i.e. chromatin in eukaryotes consists of such nucleoproteins. [2] [13]

  8. Nucleotide excision repair - Wikipedia

    en.wikipedia.org/wiki/Nucleotide_excision_repair

    Replication factor C loads the Proliferating Cell Nuclear Antigen (PCNA) onto the DNA strand. This allows DNA polymerases implicated in repair (δ, ε and/or κ) to copy the undamaged strand via translocation. DNA ligase I and Flap endonuclease 1 or the Ligase-III-XRCC1 complex seal the nicks to complete NER.

  9. Nuclear mitochondrial DNA segment - Wikipedia

    en.wikipedia.org/wiki/Nuclear_mitochondrial_DNA...

    NUMT insertion into the nuclear genome and its persistence in the nuclear genome is initiated by the physical delivery of mitochondrial DNA to the nucleus. [5] This step follows by the mtDNA integration into the genome through a non-homologous end joining mechanism during the double-strand break (DSB) repair process as envisioned by studying Saccharomyces cerevisiae, [13] [29] and terminates ...
