YourDictionary definition and usage example. The nucleolus appears to form a part of t-he Linin network, but has usually also a strong affinity for nuclear stains.
Depending on species, new nuclear envelopes may or may not form. The researches of the last twenty years have shown that the structure of the nucleus and the phenomena of nuclear division in these lower forms conforms in all essential details to those in the higher plants. Please set a username for yourself. When a new membrane forms around each of the two groups of chromosomes, division of the nucleus is complete.
Some animal cells may have division of the centrioles during this phase. Cells that become gametes are referred to as germ line cells.
When fixed and stained this granular mass is resolved into a more or less distinct granular network which consists of a substance called Linin, only slightly stained by the ordinary nuclear stains, and, embedded in it, a more deeply stainable substance called Chromatin.
