Spooling out precipitated DNA is challenging because the DNA strands are often entangled and can be difficult to separate from the surrounding alcohol (usually ethanol or isopropanol) used in the precipitation process. Additionally, the viscosity of the precipitated mass can make it hard to manipulate without breaking the DNA strands. Moreover, if not enough salt is present, the DNA may not aggregate sufficiently to form a cohesive mass that can be spooled effectively.

True and false because two DNA strands can be Identical during mitosis sometimes and sometimes not.
The connecting element between the pairs of strands that form the double helix of DNA is hydrogen bonds.
Cold ethanol is added to the soap and salt mixture during strawberry DNA extraction to precipitate the DNA from the solution. The soap helps break down cell membranes, releasing DNA, while salt aids in neutralizing the negative charges on the DNA molecules, allowing them to clump together. The cold temperature of the ethanol helps to minimize the solubility of DNA, making it more likely to form visible strands as it separates from the solution. This process ultimately makes the DNA easier to see and collect.
