Colony hybridization
Use of in situ hybridization with a labeled nucleotide probe to identify bacterial colonies that contain DNA sequences homologous to a probe.
Colony Screen. Bacterial colonies are grown on a nylon filter placed on nutrient agar.
Colony. A group of identical cells (clones) derived from a single progenitor cell.
colony - a distinct localized population within a species; includes ants, termites and bees as well as some tent caterpillars, webworms, etc.
comatose - an unconscious state; may be due to disease, injury, or poison ...
Colony Forming Unit (CFU)‚ a bacterium or small number of bacteria which grow into one observable colony on a nutrient medium
Comet heavenly body with long‚ luminous tail and elliptical orbit
(cometa = the hair of the head) ...
colony
A group of organisms of the same species living together in close association.
commensalism ...
Colony filters are plated at a density of 6 x 6 x 384, or 13,824 colonies per 8 x 12 cm filter. All colonies are plated in duplicate in a unique offset pattern optimized to prevent ambiguity in identification of positive offsets.
colony A cluster of genetically identical individuals formed asexually from a single colonizing individual.
colostrum The first secretion of the mammary glands following the birth of an infant.
columella Central pillar in gastropod shells.
A Volvox colony is an example of a colonial algae. Each Volvox is a hollow sphere with thousands of cells arranged in a single layer on its perimeter. Individual Volvox cells resemble a Chlamydomonas cell.
The Honeybee Colony
The life of the honeybee colony revolves around the activities of its single queen.
Colony liftBlot taken from colonies (normally bacterial) growing on an agar plate. Normally used for detection of a colony containing a plasmid with a specific inserted sequence (screening).
Membranes are laid onto each plate, and some of the bacteria from each colony stick, producing replicas of each colony in their original growth position.
The prion form of HET-S spreads rapidly throughout the cellular network of a colony and can convert the non-prion form of the protein to a prion state after compatible colonies have merged.
He showed that Tragopogon miscellus found in a colony in Moscow, Idaho was produced by hybridization of T. dubius and T. pratensis. He also showed that T. mirus found in a colony near Pullman, Washington was produced by hybridization of T.
There's a lot of seething activity there, more like a beehive or an ant colony. If you study an individual ant you learn something about ants but you miss the amazing things that groups of ants do together, the kind of communal behaviors they have.
One consequence of this asexual method of reproduction is that all bacterial cells in a colony are genetically the same.
coli, given a suitable environment for growth, divide and form a colony of hundreds of bacteria in just a few hours. Or visit the CELLS alive! BioCam to see bacteria colony in "real time". A longer, larger, silent version of growing E.
Suppose that a pet store owner observes that the mice in her colony grow slowly. She hypothesizes that they grow slowly because she does not give them enough food. To test this hypothesis, she uses two groups of mice.
more than two types of castes of individuals in a colony or community that belong in the same species and are derived from the same parents. The various castes of honeybees, ants, termites, and so forth are typical ...
(1) They are multicellular. It's more than being a colony of individual cells. The cells are working together for the survival of the organism. All of the cells have specific duties and responsibilities.
Polyp. An individual of a solitary coelenterate or one member of a coelenterate colony
Polyphyletic. Refers to a group of species that do not have one common ancestor species
Population density. Number of individuals per unit area or volume ...
The founder effect is the reduction in genetic variation that results when a small subset of a large population is used to establish a new colony.
plaque
A clear area in a lawn of a bacterial colony, where the bacteria have undergone lysis due to bacteriophage infection.
plasma membrane
The outer boundary of cells which is only visible with an electron microscope.
Aggregation: Organisms (usually referring to of the same species) living closely together, but not physically connected (cf. 'colony').
filter A membrane containing DNA bound to the surface. Filters in TAIR are generally from BAC, YAC, or plasmid colony libraries.
