What is the primary structure of a protein?

Back

The primary structure of a protein is the linear sequence of amino acids linked by peptide bonds.

Front

What type of bond connects amino acids in a protein's primary structure?

Back

Peptide bonds connect amino acids in a protein's primary structure.

Front

What is the secondary structure of a protein?

Back

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

Front

What type of bond is primarily responsible for the secondary structure of proteins?

Back

Hydrogen bonds are primarily responsible for the secondary structure of proteins.

Front

What is the tertiary structure of a protein?

Back

The tertiary structure of a protein is the overall three-dimensional shape formed by the folding of a polypeptide chain, stabilized by various interactions including hydrogen bonds, ionic bonds, and hydrophobic interactions.

Front

What is the quaternary structure of a protein?

Back

The quaternary structure of a protein is the arrangement of multiple polypeptide chains into a single functional unit.

Front

What is found at the 3' end of a nucleic acid?

Back

A hydroxyl group is found at the 3' end of a nucleic acid.

Front

Which end of a nucleic acid do new nucleotides add to during synthesis?

Back

New nucleotides are added to the 3' end of a nucleic acid.

Front

What is a nucleic acid?

Back

Nucleic acids are biopolymers essential for all known forms of life, primarily DNA and RNA, which store and transmit genetic information.

Front

What are the building blocks of proteins?

Back

The building blocks of proteins are amino acids.
