What does Karyology mean in biology?
Medical Definition of karyology 1 : the minute cytological characteristics of the cell nucleus especially with regard to the chromosomes of a single cell or of the cells of an organism or group of organisms. 2 : a branch of cytology concerned with the karyology of cell nuclei. Other Words from karyology.
What is studied under Karyology?
The study of whole sets of chromosomes is sometimes known as karyology. Hence, the karyology is the study of the nucleus. So, the correct answer is ‘nucleus’.
What is the meaning of Karyolysis?
Medical Definition of karyolysis : dissolution of the cell nucleus with loss of its affinity for basic stains sometimes occurring normally but usually in necrosis — compare karyorrhexis.
What does the root word karyotype mean?
Entries related to karyotype late 15c., “symbol, emblem,” from Latin typus “figure, image, form, kind,” from Greek typos “a blow, dent, impression, mark, effect of a blow; figure in relief, image, statue; anything wrought of metal or stone; general form, character; outline, sketch,” from root of.
What does Cariology mean?
The study of dental caries
[ kâr′ē-ŏl′ə-jē ] n. The study of dental caries and cariogenesis.
What is a Karyogram used for?
Today, G-banded karyograms are routinely used to diagnose a wide range of chromosomal abnormalities in individuals. Although the resolution of chromosomal changes detectable by karyotyping is typically a few megabases, this can be sufficient to diagnose certain categories of abnormalities.
What is the study of nucleus called?
Study of the nucleus is called Karyology. Karyology is a branch of Cytology (Study of Cells) ,dealing with the structure of cell nuclei, especially chromosomes.
What is karyorrhexis and Karyolysis?
Karyorrhexis is the destructive fragmentation of the nucleus of a daily cell whereby its chromatin is distributed irregularly throughout the cytoplasm. Karyolysis is a complete dissolution of the chromatin of a dying cell due to enzymatic degradation by endonucleases.
What is the study of Cariology?
Cariology deals with the study of dental caries and cariogenesis. It is concerned with dental anatomy, cariology, operative and aesthetic dentistry. It was caused by various species of oral bacteria. It can be prevented by preventing bacteria from the surface of the tooth and topical antimicrobial agents.
What is the meaning of the word karyology?
karyology(Noun) The study of the nuclei of cells, especially with regard to the chromosomes which they contain. karyology(Noun) The characteristics of a particular cellular nucleus or group of nuclei, or of the chromosomes therein.
How is karyology related to developmental and developmental biology?
In close contact with cytogenetics, developmental biology, and molecular biology, karyology studies the regular mechanisms of the transformations and function of the chromosomes and the individual parts thereof during the development and differentiation of cellular systems.
Is the structure of chromosomes a concern of karyology?
A current concern of karyology is the structure of chromosomes and chromosomal subunits (however, finding a method of constructing elementary chromosomal strands from nucleic acids and proteins is a concern of molecular biology).
