Cell differentiation always involves

(A) transcription of the myoD gene.

(B) the movement of cells.

(C) the production of tissue-specific factors

(D) the selection loss of certain genes from the genome.

The process of conversion from one cell type to the other cell type is known as cell differentiation. The specialized cells are produced as a result of cell differentiation. It is an important process in the development of multicellular organisms.

The MyoD gene is present in the muscle cell. The transcription of the myoD gene may lead to the formation of mRNA coding for the muscle cell.

Cell differentiation does not involve the transcription of the muscle protein.

Therefore, the given option is false.

Cells always tend to move in the extracellular matrix. The movement of the cell is associated with the actin protein present in the cell membrane.

Cell movement and cell differentiation are different processes.

Therefore, the given option is false.

Cell differentiation is the specialization process of cells that occurs via gene expression. The initiation of cell differentiation starts with the expression of tissue-specific factors that activate the regulatory protein. These regulatory proteins are the important control in the cell differentiation mechanism.

The tissue-specific proteins have an important role in the cell differentiation process for the activation of the regulatory proteins.

Therefore, the given option is true.

The selective loss of genes does not take place in the cell differentiation process. All proteins' coding segments are essential in the gene and need to be incorporated into the mature cells.

The gene loss does not occur in the cell differentiation process.

Therefore, the given option is false.
