Question

Differentiation results from differential gene expression.
What happens to the genetic information as the cells begin to differentiate?
A. The genes which are required in the differentiated cells are expressed from all the genes in the genetic material.
B. The nucleus contains all of the information needed for the construction of an entire organism.
C. The genetic material degrades as the cell differentiates.
D. Only the genetic information needed by the differentiated cell is retained and passed on to new cells.

Answer 1

Hint: This method of cellular differentiation is pushed with the aid of using genetics, and their interconnection with the environment. All organisms start from a unicellular. This unicellular includes the DNA coding for all the proteins the adult organism will use.

Complete answer:
To answer this question, first, we need to know about cellular differentiation. Cell differentiation is how common embryonic cells come to be specialised cells. This takes place through a manner called gene expression. Gene expression is the particular aggregate of genes which grow to become on or off (expressed or repressed), and that is what dictates how a cellular function works. Gene expression takes place due to defined alerts to our body, each outside and inside of our cells.
Now, let us find the solution from the option.
During cell differentiation, the DNA is not always modified absolutely neither there may be a loss in the quantity of genetic components however there may be moderate change within the DNA that results in an alternate within the expression of the gene. The DNA additionally undergoes methylation and acetylation that results in alteration within the genetic component and its expression.

The nucleus carries all the messages required for the development of a whole organism as earlier than and after cellular differentiation. Cellular differentiation nearly by no means includes an alternative or any degradation within the DNA collection itself. Thus, distinctive cells may have very unique bodily traits in spite of having the same genome.

All the genetic records wanted with the aid of using the differentiated cellular in retained and surpassed directly to new cells

Hence, the correct answer is option (A)

Note: All organisms start from a unicellular. This unicellular includes the DNA coding for all of the proteins the adult organism will use. However, if this cellular expressed all of those proteins immediately it might not be functional. This cell has to divide repeatedly, and the cells have to start the procedure of cellular differentiation as they divide. The cellular lines start to emerge, and the cells get an increasing number in particular. Eventually, a whole organism is shaped with loads of various cellular sorts from this technique of cellular differentiation.
