Hybridization, fluorescent in situ — An important molecular cytogenetic method for identifying chromosomes and parts of chromosomes, deciphering chromosome rearrangements, and locating genes on chromosomes. Fluorescent means emitting light that comes from a reaction within the… … Medical dictionary
Hybridization, nucleic acid — A laboratory technique in which single stranded nucleic acids (DNA or RNA) are allowed to interact so that complexes called hybrids are formed by molecules with similar, complementary sequences. Through nucleic acid hybridization, the degree of… … Medical dictionary
Hybridization probe — In molecular biology, a hybridization probe is a fragment of DNA or RNA of variable length (usually 100 1000 bases long), which is used in DNA or RNA samples to detect the presence of nucleotide sequences (the DNA target) that are complementary… … Wikipedia
hybridization — 1. The process of breeding a hybrid. 2. Crossing over between related but nonallelic genes. 3. The specific reassociation of complementary strands of polynucleic acids; e.g., the formation of a DNA RNA hybrid. 4. The process or act of forming a… … Medical dictionary
hybridization — (of nucleic acids) Technique in which single stranded nucleic acids are allowed to interact so that complexes, or hybrids, are formed by molecules with sufficiently similar, complementary sequences. By this means the degree of sequence identity… … Dictionary of molecular biology
cytological hybridization — cytological hybridization. = in situ hybridization (см.). (Источник: «Англо русский толковый словарь генетических терминов». Арефьев В.А., Лисовенко Л.А., Москва: Изд во ВНИРО, 1995 г.) … Молекулярная биология и генетика. Толковый словарь.
Nucleic acid hybridization — Hybridization is the process, discovered by Alexander Rich, of combining complementary, single stranded nucleic acids into a single molecule. Nucleotides will bind to their complement under normal conditions, so two perfectly complementary… … Wikipedia
Fluorescence in situ hybridization — A metaphase cell positive for the bcr/abl rearrangement (associated with chronic myelogenous leukemia) using FISH. The chromosomes can be seen in blue. The chromosome that is labeled with green and red spots (upper left) is the one where the… … Wikipedia
In situ hybridization — (ISH) is a type of hybridization that uses a labeled complementary DNA or RNA strand (i.e., probe) to localize a specific DNA or RNA sequence in a portion or section of tissue ( in situ ), or, if the tissue is small enough (e.g. plant seeds,… … Wikipedia
Fluorescent in situ hybridization — can be used to find out where the fluorescent probe bound to the chromosome. FISH is often used for finding specific features in DNA. These features can be used in genetic counseling, medicine, and species identification. Probes Probes are often… … Wikipedia
