Answer #1

Ans:

D. Phosphodiester linkages

Explanation: DNA and RNA are the polymer of nucleotides. Each nucleoside is consists of deoxyribose/ ribose sugar, base (A, T/U, G and C). Each nucleotide is formed by nucleosides joined together by phosphodiester linkages.The sugars of DNA and RNA are linked together by phosphodiester linkages The bases are joined together by hydrogen bonds. A pairs with T with two hydrogen bonds and G pairs with C by three hydrogen bonds. Amino acids are joined together by peptide linkages to form polypeptide and monosaccharides are joined together by glycosidic bonds to form di to polysaccharide.

The transcription of a gene involves copying DNA nucleotides from DNA into a sequence of RNA nucleotides. Many regulatory factors can help facilitate the transcription processes. One region that affects transcription is the terminator region, which is located on mRNA, downstream of the coding segment on DNA, in the 5' end of the gene on DNA, downstream of the coding segment on mRNA at the 5' end on DNA, within the coding region
