Question 1:
Exons are gene fragments whose DNA sequence after transcription is found in mature mRNAs. This part of the gene is most often coding.
The size of the exons in the genomes follows a log-normal distribution, with an average length of about 150 nucleotides, knowing that in eukaryotes, each gene contains several exons and introns (an average of 8) so the size is 8*150 = 1200 bp.
Question 2:
Introns are fragment of a gene located between two exons. Introns are present in immature mRNA and absent in mature mRNA. "Non-coding" fragment of the gene.
The introns average in a gene is 3365 bp including 3'UTR and 5'UTR and intermediate introns.
Answer:
B.
Explanation:
the answer is nucleic acid
Glucose binds to the glycogenin protein to form the glycogen polymer. Glycogen synthase uses UDP glucose as the substrate for polymerization via (1-4) bonds. The branching enzyme has two distinct functions: it breaks the linear chain and forms a branch using a (1-6) linkage.
<h3>
What are nucleotides?</h3>
A nucleotide is the primary component of nucleic acids (RNA and DNA). A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA), a phosphate group, and a nitrogen-containing base. DNA nucleotides include adenine (A), cytosine (C), guanine (G), and thymine (T). In RNA, the nucleotide uracil (U) replaces thymine. Polymeric DNA and RNA molecules are composed of long strands of nucleotides.

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.
