What is bland nuclei?
Bland nuclei is when the nucleus appears to be evenly coloured through out. There are no areas of darker colouration when stained due to being hyperchromatic or peppered. For example thyroid papillary carcinoma have bland nuclei.
A human individual is phenotypically female but her interphase somatic nuclei do not show the presence of Barr bodies what concerning her is probably true?
female
Examination of slide will show that a few nuclei do not appear next to a cell wall in onion cellCould you explain that observation?
Onion epidermal cells occur mitosis (nuclear division) and cytokinesis(cell division). Interphase cell typically have one or more number of nuclei, so a few nuclei do not appear next to a cell wall.
What 2 WBC features on a stained differential slide are studied to assist in the identification of the cell?
1. The contents ofrece thermomstat cytoplasm (whether they containt granules and 2. The shape of their nuclei (the nuclei ode leukocytes differ from each other)
How are euchromatin and heterochromatin stained?
Euchromatin is loosely coiled DNA that is transcriptionally active. An increased amount of euchromatin indicates an active cell. Heterochromatin is tightly packed DNA that is transcriptionally innactive.

The process of nuclear division which creates two new identical nuclei is called?
The process of nuclear division which creates two new identical nuclei is called mitosis.
Do the cells of hyphae often contain more than one nucleus?
Yes, some do. Filamentous fungi (PHYCOMYCETES) may contain multiple nuclei in a coenocytic mycelium.
Why WBC not getting stained with Turks fluid?
jentin violet in turks fluid stains nuclei of the cells
What HAPPENS DUR?
Mitosis is the division of the chromosomes in the nuclei. There are 5 stages in mitosis. Interphase, prophase, metaphase, anaphase, and telophase.

female
What are the structers that are in nuclei of most cells and that are made of protein and DNA?
the answer is cytosine
What is protein histone?
Alkaline proteins found in eukaryotic cell nuclei.

What is the nucleus made of?
The nucleus of what? There are all sorts of nuclei including atomic nuclei and cell nuclei. Atomic nuclei are made of protons and neutrons. Cell nuclei are made of lipids, protein, DNA and many other chemicals.
