Topic 6.1 (Module 31) DNA and RNA Structure and Function

Which of the following are examples of nucleic acids?

• DNA

• RNA

• RNA Polymerase

• exonuclease

What are the monomers of nucleic acids?

• Amino acids
• Monosaccharides
• Nucleotides
• Fatty acids

How is information stored in nucleic acids like DNA?

• Information is stored in the sequence of nucleotide bases in DNA.
• Information is stored in the proteins associated with DNA.
• Information is stored in the number of chromosomes.
• Information is stored in the shape of the DNA molecule.

What are the 3 components of a DNA nucleotide?

• Amino acid, ribose sugar, nitrogenous base
• Deoxyribose sugar, nitrogenous base, protein
• Phosphate group, deoxyribose sugar, nitrogenous base
• Phosphate group, ribose sugar, amino acid

What are the 3 components of a RNA nucleotide?

• Ribose sugar, sulfate group, nitrogenous base
• Ribose sugar, phosphate group, amino acid
• Ribose sugar, phosphate group, nitrogenous base
• Deoxyribose sugar, phosphate group, nitrogenous base

How do the sugars in RNA and DNA differ?

• RNA contains glucose while DNA contains ribose.
• The sugars in RNA (ribose) and DNA (deoxyribose) differ in the presence of an -OH group on the 2' carbon in RNA, which is absent in DNA.
• The sugars in RNA and DNA are identical in structure.
• DNA has an -OH group on the 2' carbon, while RNA does not.

Place the correct type of base with the nitrogenouse base

• purine (matches w/ thymine)

• adenine

• pyrimidine (matches w/ adenine)

• cytosine

• pyrimidine (matches w/ guanine)

• thymine

• purine (matches w/ cytosine)

• guanine

What is the primary structural difference between DNA and RNA?

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

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

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

• DNA contains uracil, while RNA contains thymine.

Which sugar is found in the structure of RNA?

• Ribose

• Deoxyribose

• Glucose

• Fructose

In RNA, which base pairs with adenine?

• Uracil
