How is it possible for gene with a mutation in coding region to encode a polypeptide with the same amino acid sequence as the nonmutant gene?

If the mutant codon still codes for the same amino acid (a silent mutation).
For example:
GUU, GUC, GUA and GUG all code for the amino acid Valine.
So if the mutation changed the codon from GUU to GUA - Valine would still be produced and therefore the polypeptide will be identical.

Which genetic change is best described by the following statement A random change in the base sequence of DNA results in an alteration of a polypeptide?
a mutation
What programs the amino acid sequence of a polypeptide?
The amino acid sequence of a polypeptide is determined by the sequence of its parent DNA. RNA is transcribed directly from DNA.
What chain is a sequence of amino acids that is the foundation for the basic structure of a protein?
polypeptide chain
What is a mutation in a DNA sequence called?
a change in the DNA sequence is a mutation, so I'm not sure what you're asking
How do you make a 10 codon sequence for a polypeptide?
A ten codon sequence for a polypeptide is formed when 10 codons. An example would be GGGAAACCCAGAAGGCGACGCCGGCGTNNN are found in an ammino acid linked by an amide bond.

What is a Missence mutation?
A mutation that causes the code for the wrong amino acid (apexvs.com)
What programs the amino acid sequence of a polypeptide?
The amino acid sequence of a polypeptide is determined by the sequence of its parent DNA. RNA is transcribed directly from DNA.
What is the relationship between the linear sequence of codons on mRNA and the linear sequence of amino acids in a polypeptide?
The linear sequence of codons on mRNA determines the linear sequence of amino acids in a polypeptide.
A change in a sequence of DNA is called?
Any change in the sequence of DNA nucleotides is called mutation.
What is the effects of mutation?
A mutation is a permenent in DNA sequence of a gene,mutation in a gene's DNA sequence can alterthe aminoacid sequence of the protein encodedby the gene.
How is it possible for a point mutation to have no effect on the function of gene?
If the point mutation does not change the protein to be translated in the 3-letter sequence, then it will have no effect on the gene's function.
What chain is a sequence of amino acids that is the foundation for the basic structure of a protein?
polypeptide chain

How does a mutation occur?
A mutation is a change from the expected nucleotide sequence of DNA. It can happen when nucleotide bases are duplicated or deleted from the sequence.
As a result of the incorrect sequence of amino acids will be translated into a protein-resulting in a mutation?
Missence mutation
