Describe how amino acids are categorized by their chemical properties. Explain how a change in the amino acid sequence of the FXR1 protein could decrease the ability of the protein to bind to RNA .

Answers

Answer:

The nature of amino acids can vary they can be acidic, alkaline, or neutral based on the functional group attached to their side-chain. The functional group of the amino acids determines the property of the hydro loving or phobic nature of particular amino acids. Interaction of different biomolecules depends on their affinities with one another such as hydrogen bonds, ionic bonds, van der Waals interaction based on structural and fundamental unit or monomer of the biomolecule.

Based on the given explanation, we can say that if there is a modification in the sequence of the building block amino acid of the FXR1 protein, might lead to a decrease in affinity to bind to the RNA by changing in the binding domain of this protein. There might be a complete structural change such that it can no longer interact with RNA.

Amino acids are grouped on the basis of their side chains.

Amino acids are categorized on the basis of their side chain attachment. All the amino acids has a specific side chain which is known as an R group. This R group is also attached to the α carbon. The R groups consist of shapes, sizes, charges, and reactivities. This allows all amino acids to be grouped or categorized on the basis of their chemical properties of their side chains.

If there is a change occur in the sequence of the building block amino acid of the FXR1 protein, it might lead to a decrease of binding to the RNA. There might be a complete change in the structure which leads no more attachment with RNA so we can conclude that amino acids are grouped on the basis of their side chains.
