The nucleus is located in the center of the cell, and A. minilatums many chloroplasts radiate outward from the nucleus.
In 1901, he showed that the chromatin in cell nuclei contains iron, and in his early years at the University of Toronto he adapted measurement methods for a number of ions (chloride, potassium and phosphorus) for use with tissue and cell samples.
Schizonts contain scant cytoplasm, are often round, do not exceed the size of the host nucleus and stick to it.
The term "C-value enigma" represents an update of the more common but outdated term "C-value paradox" (Thomas 1971), being ultimately derived from the term "C-value" (Swift 1950) in reference to haploid nuclear DNA contents.
First, the DNA material must be internalised into the cell, specifically into the nucleus.
Cytoplasmic male sterility is total or partial male sterility in plants as the result of specific nuclear and mitochondrial interactions.
They contain only one nucleus in their vegetative stage, which remains in the bottom of the cell in the holdfast at the substrate.
A dinokaryon is an eukaryotic nucleus present in dinoflagellates in which the chromosomes are fibrillar in appearance (i.e. with unmasked DNA fibrils) and are more or less continuously condensed.
Emerin, together with MAN1, is a LEM domain-containing integral protein of the inner nuclear membrane in vertebrates.
The meronts enlarge, becoming rounded or elongate and acquire up to 200 small nuclei.
Schizonts contain plentiful cytoplasm, are larger than the host cell nucleus and frequently displace it.
Heterochromatin is usually localized to the periphery of the nucleus.
The skin is from a person with systemic lupus erythematosus and shows IgG deposits at two different places: The first is a bandlike deposit along the epidermal basement membrane ("lupus band test" is positive); the second is within the nuclei of the epidermal cells (antinuclear antibodies are present).
The vaccine cures Samus and not only gives her the ability to absorb and use the nuclei of X Parasites for nourishment (the Metroids were the main predators of the X prior to their extermination by Samus on SR388), but also the Metroid's vulnerability to extremely cold temperatures.
The evidence for this relationship between myriapods and cheilcerates derives from comparisons of nuclear ribosomal RNA genes, mitochondrial ribosomal RNA genes, and protein-coding genes.
Mature schizonts are either smaller than or only slightly larger than the host nucleus.
About 106 Cell nuclei are isolated and incubated with labeled nucleotides and genes in the process of being transcribed are detected by hybridization of extracted RNA to gene specific probes on a blot.
Receptors on the cell membrane's surface designed to be activated in the presence of specific fuel molecules communicate to the cell nucleus via a means of cascading interactions.
He microscopically examined sections of sores excised in their early stages, before they ulcerated, and was able to detect oval bodies with a nucleus and a small process, which were usually located inside host cells, and made the correct conclusion that the observed organisms are the causative agents of this disease, and correctly ascribed it to Protozoa.
They tend to encircle the nucleus and the host cell tends to become oval in shape.
Schizonts are mostly round with a single mass of pigment and render the host cell nuclei spherical.
The pre-snRNA are transcribed and receive a 5’ monomethylguanosine cap in the nucleus.

The presence of DNA anywhere other than the nucleus or mitochondria is perceived as a DAMP and triggers responses mediated by TLR9 and DAI that drive cellular activation and immunoreactivity.
For example, animals undergo an "open" mitosis, where the nuclear envelope breaks down before the chromosomes separate, while fungi such as Aspergillus nidulans and Saccharomyces cerevisiae (yeast) undergo a "closed" mitosis, where chromosomes divide within an intact cell nucleus.
