1. What is primary structure of a protein 2. If I will give a protein how can u identify a protein molecular weight and size of a protein.

Question

Accepted Answer

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

The primary structure determines the protein's shape and function.
It is determined by the DNA sequence of the gene that codes for the protein.
Protein molecular weight and size can be determined by techniques such as gel electrophoresis, mass spectrometry, and size exclusion chromatography.
For example, gel electrophoresis separates proteins based on size and charge, while mass spectrometry measures the mass-to-charge ratio of protein ions.

Accepted Answer

Linear sequence of a amino acids in a peptides.
