Question

Nucleoprotein is in high quantity during
(a)Phase of wound healing
(b)Dedifferentiation
(c)Phase if blastema formation
(d)Phase of redifferentiation

Answer 1

Hint: Nucleoproteins are related to nucleic acids like DNA and RNA as well as viral nucleocapsid proteins, and are required for functions like encapsidated the virus genome for RNA transcription, packaging, and replication.

Complete answer:
During the process of Dedifferentiation, Nucleoproteins are present in high quantities.
Nucleoproteins are associated with either DNA or RNA and include ribosomes, nucleosomes, and viral nucleocapsid proteins. They participate in the regulation of DNA Replication and transcription as well as involved in homologous recombination.
The process by which cells become less specialized and within the same linkage state, returns to the earlier cell state is known as Dedifferentiation. After this process occurs, the cells may go through redifferentiation and produce more cell types than it did before.

Additional Information:
Let us know more about each process or phenomenon mentioned in the question:
The process of wound healing occurs mainly in 4 phases- The homeostasis phase, the Defensive phase, the Proliferative phase, and the Maturation phase. At the beginning of this complex process, the blood clotting system forms a dam to block the drainage of blood by the connected work of platelets and collage. The bleeding is stopped in the Homeostasis phase. The second phase i.e. defensive or inflammatory phase deals with destroying bacteria and removing debris with the help of white blood cells. After that filling and covering of the wound takes place in the proliferative phase. In the last Maturation phase, the new tissues gain strength and flexibility, and the wound healing process ends there.
The formation of the blastema is related to the regeneration of limbs in certain amphibians and is made of undifferentiated cells derived from the tissue of the region of amputation.

So, the correct answer is “dedifferentiation”.

Note:
Differentiation is the process that leads to the maturation of cells by a few major changes in the protoplasm and cell walls of the cells. For example, in the differentiation of Tracheal cells, they lose their protoplasm and develop a very strong, elastic secondary cell wall. Differentiation is understood in two types- redifferentiation and Dedifferentiation. In the later one, the cell can regain its capacity of dividing cells under certain conditions e.g. formation of interfascicular cambium and cork cambium. After Dedifferentiation, when the cell loses its capacity to divide and become mature again, then that phenomenon is called redifferentiation.
