What are polypeptide chains composed of?

Back

Polypeptide chains are composed of amino acids, which are the building blocks of proteins.

Why is an enzyme highly specific to a particular substrate?

Back

An enzyme is highly specific to a particular substrate because the shape of the enzyme's active site matches the shape of the substrate.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the Calvin cycle (light-independent reactions).

What is the difference between DNA and RNA?

Back

DNA (deoxyribonucleic acid) stores genetic information, while RNA (ribonucleic acid) plays a role in protein synthesis and gene expression.
