Answer:
These cells are able to perform specialized activities due to the 'Gene Regulation' which controls the expression of various genes.
Explanation:
Gene regulation can be explained as a process by which the cells control the expression of each gene among various genes in the genome. Gene expression is the pattern that any gene exhibits to perform certain functions or activities. For example, brain cells control the expression of the gene that exhibits characteristics like thinking, reasoning, and calculating. Such expressions are suppressed in other cells like cells of the heart. Therefore, every cell of various part expresses their gene function, and thus, perform the specialized activity in the manner their gene cells are expressed.

Hey You!
Two important underlying principles of the NIMS are flexibility and standardization.
Answer:
This implies that DNA and proteins evolved after RNA.
Explanation:
It is believed that RNA predated today's cells in evolutionary history. RNA existed as the genetic material of the primitive cells of the time that were mainly constituted of globules of fat oil suspended in water in the oceans and lakes. Even in cells today, RNA molecules themselves can act as catalysts such as in the case of peptidyl transferase reaction that takes place on the ribosome.
