Cell nucleus
In cell biology, the nucleus (pl. nuclei; from Latin nucleus or nuculeus, meaning kernel or seed) is a membrane-enclosed organelle found in eukaryotic cells.

DNA
Deoxyribonucleic acid (DNA) is a thread-like chain of nucleotides carrying the genetic instructions used in the growth, development, functioning and reproduction of all known living organisms and many viruses.

G banding
G-banding, G banding, or Giemsa banding is a technique used in cytogenetics to produce a visible karyotype by staining condensed chromosomes.

Heterochromatin
Heterochromatin is a tightly packed form of DNA or condensed DNA, which comes in multiple varieties.
New!!: Euchromatin and Heterochromatin · See more »
Histone
In biology, histones are highly alkaline proteins found in eukaryotic cell nuclei that package and order the DNA into structural units called nucleosomes.
New!!: Euchromatin and Histone · See more »
Messenger RNA
Messenger RNA (mRNA) is a large family of RNA molecules that convey genetic information from DNA to the ribosome, where they specify the amino acid sequence of the protein products of gene expression.
New!!: Euchromatin and Messenger RNA · See more »
Microscope
A microscope (from the μικρός, mikrós, "small" and σκοπεῖν, skopeîn, "to look" or "see") is an instrument used to see objects that are too small to be seen by the naked eye.
New!!: Euchromatin and Microscope · See more »
Nucleosome
A nucleosome is a basic unit of DNA packaging in eukaryotes, consisting of a segment of DNA wound in sequence around eight histone protein cores.
New!!: Euchromatin and Nucleosome · See more »
Prokaryote
A prokaryote is a unicellular organism that lacks a membrane-bound nucleus, mitochondria, or any other membrane-bound organelle.
New!!: Euchromatin and Prokaryote · See more »
Protein
Proteins are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues.
New!!: Euchromatin and Protein · See more »
RNA
Ribonucleic acid (RNA) is a polymeric molecule essential in various biological roles in coding, decoding, regulation, and expression of genes.
New!!: Euchromatin and RNA · See more »
RNA polymerase
RNA polymerase (ribonucleic acid polymerase), both abbreviated RNAP or RNApol, official name DNA-directed RNA polymerase, is a member of a family of enzymes that are essential to life: they are found in all organisms (-species) and many viruses.
New!!: Euchromatin and RNA polymerase · See more »
Transcription (biology)
Transcription is the first step of gene expression, in which a particular segment of DNA is copied into RNA (especially mRNA) by the enzyme RNA polymerase.
