What would be the molar concentration?
c = n/V. Dimension. Molar concentration (also called molarity, amount concentration or substance concentration) is a measure of the concentration of a chemical species, in particular of a solute in a solution, in terms of amount of substance per unit volume of solution.
How big is DNA in a human cell?
This allows the 3 billion base pairs in each cell to fit into a space just 6 microns across. If you stretched the DNA in one cell all the way out, it would be about 2m long and all the DNA in all your cells put together would be about twice the diameter of the Solar System.
What is the molar concentration of human DNA in human cell Class 12?
Hence, the molar concentration of DNA in each diploid cell in humans is 2.77 × 10 23 moles.
How do you find the molar concentration of DNA?
Calculate the molar concentration of DNA using the following equation: Picomoles/µl = DNA Concentration(µg/ml) / [0.66*DNA Size(bp)]…
- Dilute the DNA sample 30X by combining the following in a cuvette:
- Run on the spectrophotometer with a dilution of 30.
How much does your DNA weigh?
One dalton is 1.67 x 10-24grams, so the human genome weighs 3.59 x 10-12 grams (10-12 grams is also known as a picogram). The human genome is 3.3 x 109 bp in length.
What is the difference between plasmid DNA and chromosomal DNA?
Plasmid DNA is a part of extrachromosomal DNA that is separated from the genomic DNA. It typically occurs inside the prokaryotic cells and is circular in nature. Chromosomal DNA, on the other hand, is the genomic DNA found in prokaryotic and eukaryotic entities.
What is nM concentration?
A nanomolar (nM) is the decimal fraction of a molar, which is the common non-SI unit of molar concentration. For example, a 2-molar (2 M) solution contains 2 moles of a certain substance in one liter of a liquid or gaseous mixture. A molar (M) is the common non-SI unit of molar concentration.
How do you calculate the molarity of a cell?
Concentration formula: To find the molar concentration of a solution, simply divide the total moles of solute by the total volume of the solution in liters.
How much does a human cell weigh in grams?
They then use tabulated values to relate the index to the mass density of the red blood cells (and some other tricks to find their volumes), arriving at a mass of roughly 27 picograms (1 picogram =10-12 gram) per cell.
