FLASHCARD QUESTION

Front

Nucleic Acid Noun

[noo-klee-ik as-id]

Back

Nucleic Acid


A nitrogen-containing biological polymer involved in the storage and transmission of an organism's genetic information.

Example: This image shows that a nucleotide, the building block of nucleic acids, is made of three parts: a phosphate, a sugar, and a nitrogenous base.

FLASHCARD QUESTION

Front

Nucleotide Noun

[noo-klee-oh-tahyd]

Back

Nucleotide


The monomer of nucleic acids, consisting of a phosphate group, a five-carbon sugar, and a nitrogenous base.

Example: This diagram shows a nucleotide is made of three parts: a phosphate group, a pentose sugar, and a nitrogenous base.

FLASHCARD QUESTION

Front

Polymer Noun

[pol-uh-mer]

Back

Polymer


A large molecule, such as a nucleic acid, that is composed of many repeating smaller subunits called monomers.

Example: This image shows a polymer as a long chain made of smaller, identical repeating units, called monomers, linked together.

FLASHCARD QUESTION

Front

Monomer Noun

[mon-uh-mer]

Back

Monomer


A small, repeating molecular subunit that serves as the fundamental building block of a larger polymer molecule.

Example: This image displays simplified shapes representing different types of monomers, such as glucose and amino acids, which are the basic building blocks for larger molecules.

FLASHCARD QUESTION

Front

Phosphate Group Noun

[fos-feyt groop]

Back

Phosphate Group


An inorganic chemical group that is a key component of a nucleotide, forming the sugar-phosphate backbone of nucleic acids.

Example: This diagram shows a phosphate group, highlighted in yellow, as one of the three essential parts of a nucleotide, the building block of nucleic acids.

FLASHCARD QUESTION

Front

Nitrogenous Base Noun

[nahy-troj-uh-nuhs beys]

Back

Nitrogenous Base


A nitrogen-containing molecule that is part of a nucleotide and forms the 'letters' of the genetic code.

Example: This image shows the molecular structure of Adenine, which is one of the main nitrogenous bases that are the building blocks of DNA and RNA.

FLASHCARD QUESTION

Front

DNA (Deoxyribonucleic acid) Noun

[dee-ok-see-rahy-boh-noo-klee-ik as-id]

Back

DNA (Deoxyribonucleic acid)


A nucleic acid that contains the master plans for building all the proteins in an organism's body.

Example: This diagram shows the DNA double helix structure, labeling the sugar-phosphate backbone and the four nitrogenous bases (A, T, C, G) that form pairs.
