Final answer:
A structural gene is responsible for determining the order of amino acids in a polypeptide, encoding the protein's sequence that dictates its structure and function.. The sequence of nucleotides in the gene is translated into an amino acid sequence, where every three consecutive nucleotides, called a codon, correspond to one specific amino acid.
Step-by-step explanation:
The type of gene that determines the order of amino acids found in a polypeptide is a structural gene. These genes encode the sequence of amino acids that make up proteins and determine their structure and function. The sequence of nucleotides in the gene is translated into an amino acid sequence, where every three consecutive nucleotides, called a codon, correspond to one specific amino acid.
In the case of sickle cell anemia, a change in just one nucleotide results in a single amino acid substitution, from glutamic acid to valine, significantly altering the shape and function of the hemoglobin protein.A structural gene is responsible for determining the order of amino acids in a polypeptide, encoding the protein's sequence that dictates its structure and function.
