The spores are covered with a sheath of mucilage, which typically causes the eight spores of the ascus to be ejected together.
32.
Most are normal, but about 2 million fall into a category that doctors call Ascus, for abnormal squamous cells of undetermined significance.
33.
Meiosis then gives rise to four haploid nuclei, usually followed by a further mitotic division that results in eight nuclei in each ascus.
34.
Each nucleus divides resulting in the formation of a pair of compatible nuclei, i . e . a dikaryon, in the ascus.
35.
More than 2 million a year are deemed " ASCUS " _ they contain " atypical squamous cells of undetermined significance ."
36.
The ascus has a thickened apical ring capped by a hinged operculum; its opening often is oriented obliquely, a condition referred to as suboperculate.
37.
Blastospores and conidia bud directly, with a noticeable constriction point, from these ascospores while in the ascus as well as after they ve discharged.
38.
Abnormal squamous cells of undetermined significance is No . 2; doctors refer to it as Ascus, the category in which Anne's results fell.
39.
After formation of the ascus-initial cell, the A and a nuclei fuse with each other to form a diploid nucleus ( see Figure ).
40.
Several structural components are involved in spore discharge in " W . americana ", such as the ascus, the operculum, the suboperculum.
