A cell begins to produce a new type of protein. This is most likely due to an alteration of the 1 point structure of the cell membrane sequence of bases in a section of a chromosome chemical makeup of the cytoplasm shape of the antibodies produced by the nucleus

The correct answer is - sequence of bases in a section of a chromosome

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.

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
