 Genes encode molecules that are necessary for cell specialization.

Genes can code for nucleotides, which help to determine the specialized roles of organelles in the cell.

Protein A is a structural protein that forms long strands in the cell, while Protein B is a globular protein that functions as an enzyme.

The proteins are encoded by genes with the same sequence of nucleotides.

B The proteins have different sequences of amino acids.

The proteins are found in different parts of the body.

Genes are made up of multiple protein-encoding DNA molecules.

Genes are made up of proteins, which provide instructions for making DNA.

Genes are regions in the DNA that code for important products, such as proteins.

The different cell types each have a different genetic composition.

The cells undergo changes in their gene sequences, causing them to have different functions.

 The cells use a certain subset of their genes to code for proteins.

Genes "tell" cells to make proteins. But how do they do it? It's not like they have mouths.
