Answer:
The correct option is D. The nerve and red blood cells will turn on and off different portions of their DNA, using different genes to make different proteins.
Explanation:
A zygote is totipotent which means it has the ability to differentiate into any cell type found in the body along with the placental cells.
The nerve and red blood cells are specialized cells and they cannot differentiate into any other cell type.
All cells in the body are formed from the zygote. All the cells in the body have the same chromosomes and the same genes. However, these cells become specialized because certain part of the DNA is activated in one type of cell which helps it perform its function. Different genes are activated in different specialized cells which are able to transcribe and translate.
Enzymes can be divided into two groups, intracellular and extracellular enzymes.
Enzymes formed and retained in the cell are known as intracellular enzymes. They are found in the cytoplasm, organelles and the nucleus of the cell. Examples of such enzymes are DNA polymerase, RNA polymerase and ATP synthetase.
Extracellular enzymes are produced in the cell then packed and secreted from the cell. This kind of enzymes catalyze reactions outside the cell. Most digestive enzymes are extracellular enzymes . Examples of such are amylase, zymase and cellulase

Both prokaryotic and eukaryotic cells have a plasma membrane, ribosomes, cytoplasm, and DNA.
