These are nucleotides that have a single ring structure. Example: Cytosine, Thymine, and Uracil
IgorLugansk [536]

Answer:

The question is incomplete.

However, I notice that your question is mainly dealing with

"Nucleotides with a single ring structure"

I tackled that part, also providing explanation to the point you focused on.

Explanation:

Nucleotides are compounds in which nitrogenous bases (purines and pyrimidines) are conjugated to the pentose sugars (ribose or deoxyribose) and at least one phosphate group. Thus a nucleotide consists of a nitrogenous base, pentose sugar and at least one phosphate group.

Examples of the nitrogenous bases are Adenine, Guanine, Thymine, Uracil and Cytosine. Of all, Thymine, Uracil and Cytosine are with single ring, while Adenine and Guanine are double ring structure.

Natural selection most effective acts at the populace's heritable trends: choosing for useful alleles and, thus, growing their frequency withinside the populace, at the same time as choosing in opposition to deleterious alleles and, thereby, reducing their frequency. This procedure is referred to as adaptive evolution.

  1. Natural selection can most effective arise if there may be variant amongst contributors of the equal species.
  2. Natural selection is the procedure thru which populations of living organisms adapt and change. Individuals in a populace are certainly variable, that means that they're all exclusive in a few ways.
