Conjugation Contact

Conjugation (from Latin conjugatio - connection) is a process in which two homologous chromosomes come closer and come into direct contact with each other.

Contact conjugation occurs in prophase of the first division of meiosis I. It is the most common type of conjugation. In the process of contact conjugation, chromosomes form pairs, which are then separated into individual chromosomes.

Contact conjugation plays an important role in genetics, as it allows the exchange of genetic information between homologous chromosomes, which can lead to changes in the genetic composition of a population. Contact conjugation is also used in genetic research to study genetic variability and heredity.

However, contact conjugation can also have negative consequences, for example, in the formation of chromatid bridges, which can lead to chromosomal rearrangements and genetic abnormalities. Therefore, contact conjugation must occur under optimal conditions and with a sufficient degree of control by genetic mechanisms.

Conjugate

Ia contact - K. is located at a considerable distance from each other; the distance between the tips of the centrioles is approximately 30. µm. The term “conjugation bodies” was first proposed by I. Lax in 1941. during studies of eggs during meiosis. According to modern concepts, conjugating chromosomes are additionally held together by a special protein compound - the enzyme anaphase kinase 2, which is localized between centromeres. There are other connecting molecules. As a result, they form a compound of two complexes - bivalent (in
