A species of ciliate protozoa. It is used in biomedical research.

A genus of ciliate protozoa that is often large enough to be seen by the naked eye. Paramecia are commonly used in genetic, cytological, and other research.

The most widely distributed species of PARAMECIUM. It is elongated and possesses a bluntly pointed posterior.

The functional hereditary units of protozoa.

The smaller, reproductive, transcriptionally inert nucleus in the cells of ciliate protozoans, as distinguished from the larger, vegetative, transcriptionally active MACRONUCLEUS. Micronuclei participate in MEIOSIS and autogamy during GENETIC CONJUGATION.

The larger of two types of nuclei in ciliate protozoans. It is the transcriptionally active nucleus of the vegetative cells as distinguished from the smaller transcriptionally inert GERMLINE MICRONUCLEUS.

The complete genetic complement contained in a set of CHROMOSOMES in a protozoan.

Populations of thin, motile processes found covering the surface of ciliates (CILIOPHORA) or the free surface of the cells making up ciliated EPITHELIUM. Each cilium arises from a basic granule in the superficial layer of CYTOPLASM. The movement of cilia propels ciliates through the liquid in which they live. The movement of cilia on a ciliated epithelium serves to propel a surface layer of mucus or fluid. (King & Stansfield, A Dictionary of Genetics, 4th ed)

Deoxyribonucleic acid that makes up the genetic material of protozoa.

Proteins found in any species of protozoan.

The injection of very small amounts of fluid, often with the aid of a microscope and microsyringes.

An organization of cells into an organ-like structure. Organoids can be generated in culture. They are also found in certain neoplasms.

Cellular release of material within membrane-limited vesicles by fusion of the vesicles with the CELL MEMBRANE.

An enzyme that catalyzes the conversion of alpha D-glucose 1-phosphate to alpha D-glucose 6-phosphate. EC 5.4.2.2.

Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations.

Ribonucleic acid in protozoa having regulatory and catalytic roles as well as involvement in protein synthesis.

A species of ciliate protozoa used in genetic and cytological research.

Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.

A species of ciliated PARAMECIUM possessing two micronuclei.

Deliberate breeding of two different individuals that results in offspring that carry part of the genetic material of each parent. The parent organisms must be genetically compatible and may be from different varieties or closely related species.
