Protein targets can be readily detected and localized with single molecule resolution and objectively quantified in unmodified cells and tissues.Ferric uptake regulator family: In molecular biology, the ferric uptake regulator (FUR) family of proteins includes metal ion uptake regulator proteins. These are responsible for controlling the intracellular concentration of iron in many bacteria.Repressor: In molecular genetics, a repressor is a DNA- or RNA-binding protein that inhibits the expression of one or more genes by binding to the operator or associated silencers. A DNA-binding repressor blocks the attachment of RNA polymerase to the promoter, thus preventing transcription of the genes into messenger RNA.Silent mutation: Silent mutations are mutations in DNA that do not significantly alter the phenotype of the organism in which they occur. Silent mutations can occur in non-coding regions (outside of genes or within introns), or they may occur within exons.Tata Tapes controversy: The "Tata Tapes" controversy was a political scandal in India that was the culmination of a series of allegations of anti-national conduct levied by the then Chief Minister of Assam, Prafulla Kumar Mahanta, against the Tatas - their company Tata Tea in particular.Tata-AGP face-off: Target Tata The controversy erupted when journalist Ritu Sarin of the Indian Express broke a story that involved the illegal tapping of the telephone calls of business tycoon Nusli Wadia and published, on 4–5 October 1997, transcripts of the telephone conversations he had with Keshub Mahindra, Field Marshal Sam Maneckshaw, then Rajya Sabha Member of Parliament Jayant Malhoutra and Ratan Tata about Tata Tea's problems with the Assam Government.CpG site: The CpG sites or CG sites are regions of DNA where a cytosine nucleotide occurs next to a guanine nucleotide in the linear sequence of bases along its length. "CpG" is shorthand for "—C—phosphate—G—", that is, cytosine and guanine separated by only one phosphate; phosphate links any two nucleosides together in DNA.Protein primary structure: The primary structure of a peptide or protein is the linear sequence of its amino acid structural units, and partly comprises its overall biomolecular structure. By convention, the primary structure of a protein is reported starting from the amino-terminal (N) end to the carboxyl-terminal (C) end.ChIP-exo: ChIP-exo is a chromatin immunoprecipitation based method for mapping the locations at which a protein of interest (transcription factor) binds to the genome. It is a modification of the ChIP-seq protocol, improving the resolution of binding sites from hundreds of base pairs to almost one base pair.Hypersensitive site: In genetics a hypersensitive site is a short region of chromatin and is detected by its super sensitivity to cleavage by DNase I and other various nucleases (DNase II and micrococcal nucleases). In a hypersensitive site, the nucleosomal structure is less compacted, increasing the availability of the DNA to binding by proteins, such as transcription factors and DNase I.Enhancer (genetics)Alternative splicing: Alternative splicing is a regulated process during gene expression that results in a single gene coding for multiple proteins. In this process, particular exons of a gene may be included within or excluded from the final, processed messenger RNA (mRNA) produced from that gene.DNA sequencer: A DNA sequencer is a scientific instrument used to automate the DNA sequencing process. Given a sample of DNA, a DNA sequencer is used to determine the order of the four bases: G (guanine), C (cytosine), A (adenine) and T (thymine).List of strains of Escherichia coli: Escherichia coli is a well studied bacterium that was first identified by Theodor Escherich, after whom it was later named.Thermal cyclerIntron: right|thumbnail|270px|Representation of intron and [[exons within a simple gene containing a single intron.]]Gene polymorphismCore enzyme: A core enzyme consists of the subunits of an enzyme that are needed for catalytic activity, as in the core enzyme RNA polymerase.Genetics: Analysis & Principles, 3rd Edition.Senescence-associated beta-galactosidase: Senescence-associated beta-galactosidase (SA-β-gal or SABG) is a hypothetical hydrolase enzyme that catalyzes the hydrolysis of β-galactosides into monosaccharides only in senescent cells.Histone octamer: A histone octamer is the eight protein complex found at the center of a nucleosome core particle. It consists of two copies of each of the four core histone proteins (H2A, H2B, H3 and H4).Bivalent chromatin: Bivalent chromatin are segments of DNA, bound to histone proteins, that have both repressing and activating epigenetic regulators in the same region. These regulators work to enhance or silence the expression of genes.Epigenetic code: The epigenetic code is hypothesised to be a defining code in every eukaryotic cell consisting of the specific epigenetic modification in each cell. It consists of histone modifications defined by the histone code and additional epigenetic modifications such as DNA methylation.Infinite alleles model: The infinite alleles model is a mathematical model for calculating genetic mutations.
