Answer: Methylene blue can be used to stain DNA of a cell because it (forms ionic bonds with DNA).
Explanation:
To examine the components of a cell usually under a microscope, a stain or dye is being used to provide a clear and defined view of the area under study.
The deoxyribonucleic acid (DNA) of a cell which contains the hereditary information of the cell is located in the nucleus.
Methylene blue is a type of stain used by biologists which helps them view microscopic life in brilliant color. It is a cationic stain (positively charged blue dye); and binds to negatively charged parts of the cells, such as nucleus (DNA) and RNA in the cytoplasm (with lower affinity).
When DNA of a cell comes in contact with methylene blue on a slide, their opposite charges attract, causing methylene blue's "rings" to slide in between the "rungs" of the DNA "ladder." As a result, a rich blue stain that identifies the location of the cell nucleus can be observed. This produces a photosensitive reaction which can then be viewed under the microscope.
Therefore is can be used to stain the DNA of cell because it forms ionic bonds with DNA.
Emergency department lawsuits are becoming more rampant
nowadays, some of the most common reasons for these lawsuits are listed
below:
1. Improper and inadequate administration of medication
2. Failure to admit a patient
3. Sparse medical documentation
4. Contradictory medical documentation
5. Failure to render care
6. Inappropriate discharge or transfer
Is this not about a human? We only have one aortic arch
Dna is double stranded
rna is single stranded
sugar in dna is deoxyribose
sugar in rna is ribose
nitrogenous bases in dna are adenine thymine guanine and cytosine whereas rna has uracil instead of cytosine
dna stays in the nucleus
rna leaves the nucleus
