Explanation:
Answer: DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. ... DNA is a double-stranded molecule, while RNA is a single-stranded molecule. DNA is stable under alkaline conditions, while RNA is not stable. DNA and RNA perform different functions in humans. Like DNA, RNA is made up of nucleotides. ... There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.
Explanation:
Precipitate is the term for a solid that forms when two liquids are mixed together.
<u>True(Option a)</u>
<u></u>
Sodium ions neutralize the negative charge of DNA to facilitate precipitation. This helps the DNA come out of the solution. Detergent emulsifies cell and nuclear membranes of cells.
Detergent contains sodium laurel sulfate, which cleans dishes by removing fats and proteins. It acts the same way in the DNA extraction protocol, pulling apart the lipids and proteins that make up the membranes surrounding the cell and nucleus. Once these membranes are broken apart, the DNA is released from the cell
The detergent separates the lipid molecules, causing the membrane to break down.
