Uracil & Thymine

Explanation:

Uracil, a nucleic acid nitrogenous base, is only found in RNA and does not occur in DNA. On DNA its place is taken by Thymine base.  Marking Uracil  with a radioactive or fluorescent tag will ensure that only RNA is traced while tagging Thymine ensures that only DNA is traced.

Thymine is found in DNA because it is more stable than Uracil hence it provides an evolutionary advantage in its use to store cell information.

tamaranim1 [39]

In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents through each component.

If two or more components are connected in parallel they have the same potential difference ( voltage) across their ends. The potential differences across the components are the same in magnitude, and they also have identical polarities. The same voltage is applicable to all circuit components connected in parallel.

If each bulb is wired to the battery in a separate loop, the bulbs are said to be in parallel.
