Adenine
Adenine (A, Ade) is a nucleobase (a purine derivative).

Centromere
The centromere is the specialized DNA sequence of a chromosome that links a pair of sister chromatids (a dyad).

Chromosomal translocation
In genetics, a chromosome translocation is a chromosome abnormality caused by rearrangement of parts between nonhomologous chromosomes.

Chromosome
A chromosome (from Ancient Greek: χρωμόσωμα, chromosoma, chroma means colour, soma means body) is a DNA molecule with part or all of the genetic material (genome) of an organism.

Cytogenetics
Cytogenetics is a branch of genetics that is concerned with how the chromosomes relate to cell behaviour, particularly to their behaviour during mitosis and meiosis.
New!!: G banding and Cytogenetics · See more »
Cytosine
Cytosine (C) is one of the four main bases found in DNA and RNA, along with adenine, guanine, and thymine (uracil in RNA).

Euchromatin
Euchromatin is a lightly packed form of chromatin (DNA, RNA, and protein) that is enriched in genes, and is often (but not always) under active transcription.
New!!: G banding and Euchromatin · See more »
GC-content
In molecular biology and genetics, GC-content (or guanine-cytosine content) is the percentage of nitrogenous bases on a DNA or RNA molecule that are either guanine or cytosine (from a possibility of four different ones, also including adenine and thymine in DNA and adenine and uracil in RNA).

Genetic disorder
A genetic disorder is a genetic problem caused by one or more abnormalities in the genome.
New!!: G banding and Genetic disorder · See more »
Giemsa stain
Giemsa stain, named after German chemist and bacteriologist Gustav Giemsa, is used in cytogenetics and for the histopathological diagnosis of malaria and other parasites.
New!!: G banding and Giemsa stain · See more »
Guanine
Guanine (or G, Gua) is one of the four main nucleobases found in the nucleic acids DNA and RNA, the others being adenine, cytosine, and thymine (uracil in RNA).
New!!: G banding and Guanine · See more »
Heterochromatin
Heterochromatin is a tightly packed form of DNA or condensed DNA, which comes in multiple varieties.
New!!: G banding and Heterochromatin · See more »
Homologous chromosome
A couple of homologous chromosomes, or homologs, are a set of one maternal and one paternal chromosome that pair up with each other inside a cell during meiosis.
New!!: G banding and Homologous chromosome · See more »
Karyotype
A karyotype is the number and appearance of chromosomes in the nucleus of a eukaryotic cell.
New!!: G banding and Karyotype · See more »
Metaphase
Metaphase (from the Greek μετά, "adjacent" and φάσις, "stage") is a stage of mitosis in the eukaryotic cell cycle in which chromosomes are at their second-most condensed and coiled stage (they are at their most condensed in anaphase).
New!!: G banding and Metaphase · See more »
R‑banding
R-banding is a cytogenetics technique that produces the reverse of the G-band stain on chromosomes.
New!!: G banding and R‑banding · See more »
Staining
Staining is an auxiliary technique used in microscopy to enhance contrast in the microscopic image.
New!!: G banding and Staining · See more »
Telomere
A telomere is a region of repetitive nucleotide sequences at each end of a chromosome, which protects the end of the chromosome from deterioration or from fusion with neighboring chromosomes.
New!!: G banding and Telomere · See more »
Thymine
---> Thymine (T, Thy) is one of the four nucleobases in the nucleic acid of DNA that are represented by the letters G–C–A–T.
New!!: G banding and Thymine · 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.
New!!: G banding and Transcription (biology) · See more »
Trypsin
Trypsin is a serine protease from the PA clan superfamily, found in the digestive system of many vertebrates, where it hydrolyzes proteins.
