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.

Meiosis is a type of cell division that occurs within the human body. Watch the video on meiosis, and then answer the following
Ugo [173]

The goal of meiosis is produce gametes, or sex cells. During meiosis, four daughter cells are produced, each of which are haploid (containing half as many chromosomes as the parent cell).

<h3><u>What are the stages of meiosis ?</u></h3>

Because meiosis involves two distinct cell divisions, a parent cell can generate four gametes (eggs in females, sperm in males). Cells move through prophase, metaphase, anaphase, and telophase with each cycle of division.

A cell must first pass through interphase before beginning meiosis I. The interphase that precedes mitosis is the same as this one. The cell develops, duplicates its chromosomes, and gets ready to divide.
