Landmark discovery of the physical state of complex DNA and protein "packages"-called chromatin-in a cell's nucleus could lead to better understanding of diseases such as cancer. (ualberta.ca)
In a study published in the journal Cell , the research team, led by Professor Michael Hendzel of the Faculty of Medicine & Dentistry and collaborator Jeffrey Hansen from Colorado State University, found that chromatin is neither a solid nor a liquid, but something more like a gel. (ualberta.ca)
Previously, fields such as biochemistry operated under the assumption that chromatin and other elements of the nucleus operated in a liquid state, Hendzel said. (ualberta.ca)
In the case of chromatin, it's about scaling this principle down to the level of the cell nucleus, because it is all connected. (ualberta.ca)
Inside the nucleus of a cell, the chromatin fibre interacts with itself to condense into a chromosome. (ualberta.ca)
The team's findings bridge research done over the past 50 years on chromatin gels produced in the laboratory to demonstrate its existence in living cells, which has major implications for interpreting their elastic and mechanical properties, Hendzel explained. (ualberta.ca)
For example, recent studies have shown that the deformability of chromatin in cancer cells is an important determinant of their ability to squeeze through small spaces to travel outside a tumour and metastasize elsewhere in the body-something that is much easier to explain if chromatin is gel-like rather than a liquid.

Although both types of cells can replicate their DNA and then divide it among two new daughter cells, the systems by which prokaryotes and eukaryotes distribute the DNA among the daughter cells are completely different. (uu.nl)
Eukaryotes are the type of cells that have a nucleus. (proprofs.com)
Eukaryotes are likely the most recently evolved type of cell because they are more complex and have a nucleus, which prokaryotes lack. (proprofs.com)
These characteristics suggest that eukaryotes have undergone more evolutionary changes and adaptations over time compared to prokaryotes, making them the most recently evolved cell type. (proprofs.com)

This means that these key amino acids are required to form the X-shaped chromosome. (le.ac.uk)

Those energy-producing organelles are inherited from a mother and have their own DNA, distinct from the genetic information - from both parents - that's stored in a cell's nucleus . (dictionary.com)
They have their own DNA which is passed down by the mother and is distinct from the chromosomes in the nucleus. (newscientist.com)
Chromosomes, distinct structures made up of DNA and protein, are located in the nucleus of each cell. (medicinenet.com)
This new cell, which is microscopic, will multiply and organize perfectly all distinct tissues to generate a full grown individual with organs and systems as complex as brain and immune system. (bvsalud.org)

It causes immediate abnormalities in a person's blood, and the infected person's white cell count continues to drop throughout the course of the disease, even during the intermediate stage when its attack is concentrated in the lymph nodes. (justia.com)
A karyotype is a picture of the full set of chromosomes in a person's cells. (msdmanuals.com)

This site is here to help you learn about the plant cell! (protopage.com)
Chloroplasts are extremely important organelles, and the more a cell has, the healthier and more efficient the plant is. (protopage.com)
The nucleus of the plant cell is on the inside of the plant cell in most opinions is the brain and power behind the cell. (protopage.com)
There is one vacuole in a plant cell. (protopage.com)
As you can see, the vacuole takes up a lot of room in each plant cell. (protopage.com)
In this paper some aspects of the occurrence of plant polytenes will be summarized along with the structure and function of these chromosomes. (scielo.br)
Replicate plant cells or protoplasts that are placed under identical conditions of tissue culture do not always grow and differentiate to produce identical progeny (clones). (jrank.org)
Advantage has been taken of the natural ability of Agrobacterium to transfer plasmid DNA into the nuclei of susceptible plant cells. (jrank.org)
Agrobacterium cells with a genetically-modified plasmid, containing a gene for the desired trait and a marker gene, usually conferring antibiotic resistance, are incubated with protoplasts or small pieces of plant tissue. (jrank.org)
Plant cells that have been transformed by the plasmid can be selected on media containing the antibiotic, and then cultured to generate new, transgenic plants. (jrank.org)
Two methods have been developed for direct gene transfer into plant cells-electroporation and biolistics. (jrank.org)
Plant cells (unlike animal cells) are surrounded by a thick, rigid cell wall. (enchantedlearning.com)
An organelle in some plant cells that stores starch. (enchantedlearning.com)
The cell wall also bonds with other cell walls to form the structure of the plant. (enchantedlearning.com)
Unlike the centrosomes in animal cells, plant cell centrosomes do not have centrioles. (enchantedlearning.com)

One of each chromosome pair is inherited from the mother and the other is inherited from the father. (healthywomen.org)

Located in nucleus and spindle midzone. (nih.gov)
Synovial sarcomas encompass both biphasic (epithelial and spindle cell components) and monophasic (purely spindle cell) variants. (medscape.com)
DSRCT is composed of small cells with round hyperchromatic nuclei and a dense fibrous or spindle cell stroma. (medscape.com)

Confocal microscopy demon- exposures to workers likely during the production strated nanotubes within the nucleus that were in or use of commercial products. (cdc.gov)

The mitochondrion converts the energy stored in glucose into ATP (adenosine triphosphate) for the cell. (enchantedlearning.com)

Spirochaetes of the genus Borrelia are a notable exception to this arrangement, with bacteria such as Borrelia burgdorferi, the cause of Lyme disease, containing a single linear chromosome. (wikipedia.org)
You might think that a fungus more closely resembles bacteria than it does us", says Geert Kops, cell biologist at the Hubrecht Institute. (uu.nl)
Bacteria, on the other hand, are prokaryotes and do not have a nucleus. (proprofs.com)

When the muscle cells of affected individuals are stained and viewed under a microscope, these cells usually appear abnormal. (medlineplus.gov)
These abnormal muscle cells are called ragged-red fibers. (medlineplus.gov)
Possibly, the abnormal huntingtin protein undergoes proteolysis and is then transported to the nucleus, where it undergoes aggregation. (medscape.com)

The endoreduplication cycle differs from endomitosis because it results in polytene cells (cells with many identical paired chromatids). (scielo.br)
And then, once that last chromosome has joined the rest, all of a sudden all of the chromatids let go and move to their own half. (uu.nl)

The first-line treatment typically includes chemotherapy combined with immunotherapy, which is a combination of medications that destroy the cancer cells. (rarediseases.org)

are structures within cells that use oxygen to convert the energy from food into a form cells can use through a process called oxidative phosphorylation . (medlineplus.gov)

When cells divide, the DNA becomes packed as tightly organised X-shaped chromosomes that are then evenly distributed to the two daughter cells. (le.ac.uk)
Normally cells grow and multiply in a very tightly controlled and organised way. (lymphoma.org.au)

Aneuploidy is an abnormality in the number of chromosomes in a cell due to loss or duplication. (genome.gov)
