The RNA molecules mostly occur as a:
Correct answer: C. Single stranded structure
- A. Duplex
- B. Double stranded structure
- C. Single stranded structure
- D. Genetic material
Explanation
A single-stranded structure refers to a molecule that consists of only one chain of nucleotides or monomers, as opposed to the double-stranded structure where two complementary strands are paired together. The context in which "single-stranded" is used often pertains to nucleic acids, such as RNA (ribonucleic acid) or certain types of DNA.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
