What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid or stop signal during protein synthesis.

Front

What happens to an enzyme when it is denatured?

Back

When an enzyme is denatured, its shape is altered, which affects its ability to function properly.

Front

What is the active site of an enzyme?

Back

The active site is the region on the enzyme where substrate molecules bind and undergo a chemical reaction.

Front

What is a substrate in the context of enzymes?

Back

A substrate is the reactant molecule upon which an enzyme acts.

Front

Where does transcription occur in a cell?

Back

Transcription occurs in the nucleus of the cell.

Front

What is a catalyst?

Back

A catalyst is a substance that speeds up a chemical reaction without being consumed in the process.

Front

What role do ribosomes play in protein synthesis?

Back

Ribosomes are the cellular structures where proteins are synthesized by translating mRNA into amino acid sequences.

Front

What is the primary structure of a protein?

Back

The primary structure of a protein is the linear sequence of amino acids that make up the protein.

Front

How does temperature affect enzyme activity?

Back

Increasing temperature generally increases enzyme activity up to a certain point, after which the enzyme may denature and lose function.

Front

What is the difference between DNA and RNA?

Back

DNA contains the genetic blueprint for an organism, while RNA is involved in protein synthesis and can act as a messenger.
