Example sentences for: achiasmatic
How can you use “achiasmatic” in a sentence? Here are some example sentences to help you improve your vocabulary:
The rec12 null and active site mutants are achiasmatic and, as anticipated, Rec12-dependent crossovers (chiasmata) are required to ensure proper reductional chromosome segregation in MI.
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.
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.
We propose that the Rec12-Y98F protein facilitates distributive segregation of achiasmatic chromosomes during MI.
Rec12 is required for chiasmatic and achiasmatic chromosome segregation during MI; and its active site tyrosine is required for chromosome segregation during MII
