Biochemistry - Nucleic Acids

What are the components of each nucleotide? *

a phosphate group, a sugar molecule, and a nitrogen base

Which is the correct arrangement for a single DNA nucleotide? *

deoxyribose sugar → a phosphate → a base

Which organic molecule is paired with its basic building block? *

nucleic acid : nucleotides

All organisms contain DNA and RNA. What are the subunits of DNA and RNA? *

nucleotides

What are the subunits of DNA and their function? *

nucleotides that store information

Which would best distinguish a nucleic acid from a carbohydrate?

presence of phosphate

Which statements explain the primary difference between the structure of a nucleic acid and the structure of a protein? *

Nucleotides link together to form a nucleic acid. Amino acids link together to form a protein.

While trying to identify molecules and compounds within a cell, a scientist stumbles upon a nucleic acid that contains the nitrogenous base uracil, the sugar ribose, and is single-stranded. Which nucleic acid has this scientist most likely found? *
