Transcript text: DNA and RNA are examples of
Select one:
A. catalysts
B. lipids
C. nucleotides
D. enzymes
Solution
The answer is C: nucleotides.
Explanation for each option:
A. Catalysts - Catalysts are substances that increase the rate of a chemical reaction without being consumed in the process. DNA and RNA are not catalysts.
B. Lipids - Lipids are a group of naturally occurring molecules that include fats, waxes, sterols, and fat-soluble vitamins. DNA and RNA are not lipids.
C. Nucleotides - Nucleotides are the building blocks of nucleic acids like DNA and RNA. Each nucleotide consists of a sugar, a phosphate group, and a nitrogenous base. Therefore, DNA and RNA are composed of nucleotides.
D. Enzymes - Enzymes are proteins that act as biological catalysts. DNA and RNA are not enzymes.
