Answer:
The correct answer is 1 and 4, thus
Testing for the presence of 1. Thymine (DNA) and 4. Uracil (RNA)
Explanation:
DNA and RNA differ in the composition of their nucleotides in that one of their four nucleotide organic bases differs in the two polymers. While bases adenine, guanine, and cytosine are present in RNA and DNA; only DNA contains thymine DNA, and only RNA contains uracil. These components, Adenine, Guanine, Thymine, Uracil and Cytosine are abbreviated as A, G, T, U, and C, respectively. Their acronyms above are used to represent long complexes formed by these bases.
Answer:True
Explanation:
A ideal solution is a solution which obeys Raoults law on almost every concentration and temperature range.
Ideal solutions are formed by mixing those solute and solvent which has identical molecular properties.
Lets take A be the solute and B be the solvent so to form a ideal solution from these components the solute-solute(A-A) molecular interaction and solvent -solvent (B-B) molecular interactions must be identical with the solute solvent interaction(A-B).
The solute-solute molecular interaction ,solute-solvent molecular interaction and solvent-solvent molecular interaction must be equal in order to form a ideal solution.
The enthalpy of mixing and volume of mixing of ideal solution is zero.
enthalpy of mixing is the amount of energy released on mixing a solute and solvent and in case of ideal solutions it is zero.
Volume of mixing is change in volume on mixing a solute and solvent.
