First, the precursor of chromatoid body adhered to the inner surface of the nuclear envelope.The nuclear envelope where the chromatoid body adhering was destroyed.
Results Compared with control group,the changes of neuronic ultrastructure in hippocampus CA1 in high preference group and low preference group were more severes.
The acidophil erythroblast and erythrocyte had more hemoglobin in the euchromatin areas of nuclei, less nuclear pores, and wider perinuclear space than polychromatophil erythroblast.
Nuclear envelopes reform and cleavage or cell plate formation eventually produces a total of four daughter cells, each with a haploid set of chromosomes.
The capsid is covered by a protein layer called the tegument, and finally enclosed in an envelope, which is a lipid membrane that contains viral glycoproteins and is acquired from the nuclear membrane of host cells.
