C. Because both reactants and products continue to form.
Answer:
ΔE = 5.02 x 10⁻¹⁹ j
Explanation:
ΔE (photon) = h·f = (6.63 x 10⁻³⁴ j·s)(7.57 x 10¹⁴ s⁻¹) = 5.02 x 10⁻¹⁹ j
h = Planck's Constant = 6.63 x 10⁻³⁴ j·s
f = frequency (given) = 7.57 x 10¹⁴ s⁻¹

Answer:
- Adenine
- Guanine
- Thymine
- Cytosine
Explanation:
The nitrogen bases that form DNA are derivatives of pyrimidine and purine, both organic molecules with a heterocyclic ring.
In RNA, thymine is replaced by Uracil.
