Answer;

-Green plants are responsible for oxygen in the atmosphere.

Explanation;

-Green plants undertake a process of photosynthesis, in which they use energy from the sun, carbon dioxide and water to form simple sugars and also release oxygen to the atmosphere. The simple sugars from the process may be used by the cells for energy or be stored in form of energy for future use.

-Oxygen is a product of photosynthesis which is released to the atmosphere.

-NH and C = O

At the same time, it inhibits the hydrogen bonds of the side chains from influencing the reaction process.

The polypeptide secondary structure shows the dexterity to curl or fold as sustained by the polypeptide chains.

Answer: No

Explanation: if a nucleic acid contains uracil then it is not DNA it's an RNA. Uracil is the basic nitrogenous base of RNA. DNA does not have Uracil in its structure. It contains thiamine instead of Uracil. So the answer is NO.
