Answer:
The correct answer is - sequence of bases in a section of a chromosome
Step-by-step explanation:
Protein synthesis is possible due to the nitrogenous base sequence of DNA molecules that acts as the template for the synthesis of the RNA molecule which moves to the cytoplasm and produces the Protein molecules from the sequence of mRNA that codes for specific amino acids according to the triplet codes.
So, the DNA or chromosomes are responsible for the synthesis of specific protein production and if there is any change in the sequence of bases in the DNA section it will lead to a new type of protein.
