Example sentences for: achiasmatic

How can you use “achiasmatic” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • In the presence of Rec12-Y98F protein the checkpoint would be active, thereby allowing the achiasmatic chromosomes sufficient time to reorient and undergo distributive segregation.

  • Second, catalytically-inactive Rec12 protein facilitates achiasmatic (distributive) segregation.

  • The rec12 mutant meioses are achiasmatic and would thus be expected to suffer chromosome segregation errors during meiosis I. To gain insight into this possibility, asci from meiotic cultures were stained with a DNA specific fluorescent dye (DAPI) and visualized by differential interference contrast (DIC) and fluorescence microscopy.

  • In the absence of Rec12 protein and crossovers, a backup distributive (achiasmatic) segregation system operates successfully on up to half of the chromosomes that would otherwise undergo MI nondisjunction.

  • In female meioses of D. melanogaster , heterochromatic pairing of homologs can substitute for chiasmata to ensure bipolar spindle attachment of bivalents and subsequent distributive segregation [ 4 5 6 8 ] . Rec12 may serve a similar role in maintaining a paired (or pseudo-paired) state between achiasmatic chromosomes prior to the first meiotic division.
