Answer :
When distinct proteins are produced as a result of cells creating various types of nitrogenous bases or amino acids, cell differentiation can take place.
- As a result of cellular differentiation, a stem cell might transform into a new type.
- Usually, the cell changes into a different kind that is more specialized.
- These changes result from changes in gene expression. Cell differentiation is demonstrated by how a single-celled zygote develops into a multicellular embryo and eventually into the complex multisystem of several cell types that is a fetus.
The nitrogenous bases that make up the nucleic acids—adenine, cytosine, guanine, thymine, and uracil—come from a few amino acids and their precursors.
