सेंट्रोमेरे इसके अंग्रेजी अर्थ का उदाहरण

He studied [and A spindle poison, also known as a spindle toxin, is a poison that disrupts cell division by affecting the protein threads that connect the centromere regions of chromosomes, known as spindles.

Attention is paid to their length, the position of the centromeres, banding pattern, any differences between the sex chromosomes, and any other physical characteristics.

Classical satellite DNA is normally heavily methylated at cytosine residues but may become almost fully unmethylated due to ICF syndrome (Immunodeficiency, centromere instability, and facial anomalies syndrome) or after treatment by DNA methyl transferase inhibitors.

Since assembly of kinetochore proteins at centromeres is affected by the methylation of cytosine and histone proteins, a reduction in heterochromatin integrity as a result of hypomethylation can interfere with microtubule attachment to chromosomes and with the sensing of tension from correct microtubule-kinetochore connections.

- In December 2011 the study published in Developmental Cell by Lar Jansen and his team uncovered a very simple, neat mechanism whereby the cell couples DNA duplication, cell division and centromere assembly.

By using the same machinery for all these steps but in opposite ways, the cells confirm that the right number of copies of both genes and centromeres are made by allowing each the appropriate time.

The ASL gene is located on chromosome 7 between the centromere (junction of the long and short arm) and the long (q) arm at position 11.

This violation of mendelian segregation was later shown to be the result of an array of Kindr genes at present on the end of chromosome 10 which induce neocentromere activity in maize knobs, causing copies of maize chromosomes carrying knobs to preferentially reach the egg cell during female meiosis.

Lakes of Renfrew County An acentric fragment is a segment of a chromosome that lacks a centromere.

Because the centromere is the point of attachment for the mitotic apparatus, acentric fragments are not evenly distributed to the daughter cells in cell division (mitosis and meiosis).
