Final answer:
Nucleic acids are macromolecules essential for life, composed of nucleotides that form DNA and RNA. DNA stores genetic information, while RNA is key in protein synthesis. The true statements about nucleic acids include that nucleotides are their monomers, and both DNA and RNA are types of nucleic acids.
Step-by-step explanation:
Nucleic acids are critical biomolecules essential to all forms of life. They are formed by monomers known as nucleotides, which join to create polynucleotide chains. The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
DNA is a double-stranded molecule that carries the genetic instructions used for growth, development, functioning, and reproduction. On the other hand, RNA is a single-stranded molecule that plays a crucial role in protein synthesis and regulation.
Regarding the question, the correct statements about nucleic acids are: nucleotides are the monomers of nucleic acids, DNA is an example of a nucleic acid, and RNA is an example of a nucleic acid. Contrary to one of the options provided, nucleic acids are not micromolecules; they are actually very large macromolecules.
In summary, the correct options in the final answer include: nucleotides are the monomers of nucleic acids, DNA is an example of a nucleic acid, and RNA is an example of a nucleic acid.
