How does the structure of an amino acid relate to its function in cellular process? use the role of amino acids in the structures of proteind as supportive evidence.

The chemical composition of the side chain determines the function of the amino acids. The function of a protein depends on the sequence and the number of amino acids in it.

Explanation:

The function of an amino acid primarily depends on the different side chains present in an amino acid. These different side chains are normally referred as the "R Group".

The protein function is determined by the series of amino acids that the protein possesses. A change in any one of the amino acids will cause change in the structure of the protein. When the structure of a protein changes, it will not be able to perform its function. Hence, the structure of amino acids plays a vital role in the functions of a cell.

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
