<span>This organelle is the nucleolus.
The nucleolus is made of proteins, DNA, and RNA. They form around specific regions of the chromosomes called nucleolar organizing regions. These regions of the chromosomes contain some the genes needed for ribosome production.</span>
E.coil bacteria is belong to family of Enterobacteriaceae . Its live in the environment with or without oxygen.They also present in the intestine of healthy person and warm blooded animals.
The quantity of lactate produce by pathogenic E-coli was significantly higher than produced by non -E-coli.These enzymes were produced by lactose but represent by glucose and galactose.
E-coli used as disaccharide lactose as source of metabolic energy.Fermentation of lactose , glucose and galactose using E-coli bacteria.And lactose is produced by bacteria living in the intestinal tract of animals .It is an energy source and E-coli use use glucose as an energy source.

To identify, map, and evaluate the underlying biochemical processes of cell signaling, it is essential to visualize cells and cellular structures as well as track and modify nucleic acids and proteins in living cells.
<h3>How cell labeling of mammalian cells done?</h3>
- Mammalian cells can be magnetically labeled by combining ferumoxides or superparamagnetic iron oxide (SPIO) with transfection agents (TAs).
- The effectiveness and survivability of cell labeling with TAs complexed to SPIO have not been systematically compared. This study examines the toxicity and labeling effectiveness of FEs complexed to various TAs in mammalian cells at various doses.
- TAs from several classes, including lipid-based substances, dendrimers, and polycationic amines, were employed.
- TAs at concentrations ranging from 1 to 50 microg/mL in incubation media were used to measure the cellular toxicity. Combining varying doses of TAs with various amounts of FEs allowed researchers to calculate the iron incorporation efficiency.
