Example sentences for: achiasmatic

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

  • However, the frequency of MI nondisjunction observed is only half of that expected, suggesting the presence of a distributive (achiasmatic) system of chromosome segregation.

  • 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.

  • A meiotic checkpoint could provide additional time for missegregating chromosomes to correct their erroneous wanderings during MI [ 10 ] . We propose two likely mechanisms by which the Rec12 protein improves the MI segregation of achiasmatic chromosomes.

  • The rec12-D15 (null) mutants are achiasmatic (Table 1) and, as anticipated, exhibit a high frequency of MI nondisjunction (Figures 3, 5, Table 2).

  • The respective contributions of chiasmatic and achiasmatic (distributive) modes of chromosome segregation can be studied in organisms with naturally-occurring achiasmatic chromosomes [ 8 ] , in cells harboring non-recombined artificial chromosomes [ 9 ] , and in achiasmatic mutants [ 10 ] . Among achiasmatic mutants, those lacking the Spo11 (Rec12) protein are of particular interest because Spo11 has a key role in the initiation of recombination [ 11 ] .
