Front

What are ionic attractions in amino acids?

Back

Ionic attractions occur between positively and negatively charged R groups of amino acids, influencing protein structure and function.

Front

What is the structure of RNA?

Back

RNA is a nucleic acid composed of ribose sugars, phosphate groups, and nitrogen bases (adenine, guanine, cytosine, and uracil).

Front

What characterizes a saturated triacylglycerol?

Back

A saturated triacylglycerol contains the maximum number of hydrogen atoms in its fatty acid chains, with no double bonds.

Front

What is an example of a hydrogen bond?

Back

The attraction between a hydrogen atom of one water molecule and the oxygen atom of another water molecule.

Front

What does the quaternary structure of a protein refer to?

Back

The quaternary structure refers to the arrangement of multiple polypeptide chains in a protein.

Front

What is the primary structure of a protein?

Back

The primary structure is the linear sequence of amino acids in a polypeptide chain.

Front

What is the secondary structure of a protein?

Back

The secondary structure refers to local folded structures that form within a polypeptide due to hydrogen bonding, such as alpha helices and beta sheets.

Front

What are nitrogen bases in nucleic acids?

Back

Nitrogen bases are the building blocks of nucleic acids, including adenine, thymine, cytosine, and guanine.

Front

What is the role of phosphate groups in nucleic acids?

Back

Phosphate groups link the sugar molecules in the backbone of nucleic acids, providing structural integrity.

Front

What is the difference between DNA and RNA?

Back

DNA contains deoxyribose sugar and thymine, while RNA contains ribose sugar and uracil.
