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.

What is the function of mRNA?
stich3 [128]

mRNA

Messenger RNA is used to copy and encode genetic information from DNA base pairs by forming complementary strand of RNA molecule from the nucleus of the cell to the cytoplasm.

tRNA

Transfer RNA reads sequence of nucleotide from messenger RNA and translate them into proteins or amino acids during proten synthesis.

Transcription

This is the first step in gene expression where information from DNA is copied into a complementary strand of RNA molecule using RNA polymerase enzyme.

Translation

Messenger RNA made from the process of transcription travels to the ribosomes in the cytoplasm where proteins are produced using transfer RNA to copy the information.

The use of DNA to make proteins.

Through gene expression (central dogma of biology), the DNA molecule carries information, a gene code, in form of base pairing sequences that are transcribed to RNA and further translated to functional proteins or amino acids.
