Question

Which pair of characteristics of RNA enables it to take on different shapes that allow it to bind to diverse substances in solution and to speed up chemical reactions? a. it’s pentose sugars and phosphate groupsb. it’s hydroxyl groups bound to sugar residues and its ability to hydrolyze into nucleotide monomersc. it’s linear structure and repeating phosphodiester bondsd. it’s single stranded structure and complimentary base pairse. it’s capacity for forming hydrogen bonds and it’s hydrophilic nature

Answer 1

D. it’s single stranded structure and complimentary base pairs

Step-by-step explanation:

RNA which is ribonucleic acid which is a complex organic molecule which constitutes of major essential macromolecules which are lipids, proteins and carbohydrates. Unlike DNA, RNA is more often found in nature as a single strand folded onto itself, rather than a paired double strand and has the unique ability to base-pair with itself and other nucleic acids to form complex structures. RNA are found in the cytoplasm of human cells as transfer RNA (tRNA), ribosomal RNA (rRNA) and messenger RNA (mRNA).

All RNAs have a 2’-hydroxyl group in the ribose sugar ring, and the reactivity of the 2'-hydroxyl in RNA is by local nucleotide flexibilitythat is, the 2'-hydroxyl is very reactive at single-stranded and its flexible positions.
