How many nucleotides make up one rung of DNA?

four nucleotides

Explanation:

(adenine and guanine) have a double ring structure while the pyrimidine bases (thymine and cytosine) have only a single ring.

The answer IS 4 nucleotides.

Explanation:

the most common energy conversion is from kinetic energy to potential energy, and then from potential energy to kinetic energy.

later on comes the heat energy, mechanical energy, and other energy conversions.

this energy conversion is so common that we can find it in our day to day lives as well.

- one of the most common energy conversions involves the changing of potential energy to kinetic energy or kinetic energy to potential energy

nucleus

would be most reasonable answer tbh
