DNA and RNA Structure and Function

DNA is famously known for its structure, which is described as a:

• Single helix

• Triple helix

• Double helix

• Linear chain

In eukaryotic cells, where is DNA primarily located?

• Cytoplasm

• Ribosomes

• Nucleus

• Mitochondria

In eukaryotic cells, where can RNA be found?

• Only inside the nucleus.

• Only outside the nucleus.

• Both inside and outside the nucleus.

• Only within the mitochondria.

In prokaryotic cells, which lack a nucleus, where are DNA and RNA typically found?

• Both DNA and RNA are confined to a specialized nucleus.

• DNA is in the nucleus, and RNA is in the cytoplasm.

• Both DNA and RNA are located in the cytoplasm.

• DNA is in the nucleoid region, and RNA is only in the ribosomes.

Both DNA and RNA are classified as which type of biomolecule?

• Carbohydrates

• Lipids

• Proteins

• Nucleic Acids

What are the basic building blocks, or monomers, of nucleic acids like DNA and RNA?

• Amino acids

• Monosaccharides

• Nucleotides

• Fatty acids

A nucleotide, the monomer of nucleic acids, consists of which three components?

• An amino acid, a sugar, and a phosphate group.

• A fatty acid, glycerol, and a phosphate group.

• A phosphate group, a sugar, and a nitrogenous base.

• Glucose, fructose, and galactose.

Which of the following best describes the general structural difference between DNA and RNA?

• DNA is typically single-stranded, while RNA is double-stranded.

• DNA forms a double helix, while RNA is generally a single strand.

• DNA contains ribose sugar, while RNA contains deoxyribose sugar.

• DNA is found only in the nucleus, while RNA is found only in the cytoplasm.

What type of sugar is a component of DNA?

• Ribose

• Deoxyribose

• Glucose

• Fructose

If one strand of DNA has the sequence A-T-G-C, what would be the complementary sequence on the other DNA strand?

• T-A-C-G

• U-A-C-G

• A-T-G-C

• G-C-A-T
