Answer: C
Explanation: Cells reproduce and divide through a process called mitosis
Shortly after gastrulation, the body and organs of the embryo begin to form. This process is called <u>embryogenesis.</u>
<u></u>
- The process by which an embryo transforms into a fetus is known as embryogenesis.
- The three germ layers that eventually give rise to the various organs in the animal body are formed as a result of gastrulation.
- Embryogenesis is the name of this process. As a result of differentiation, organs emerge from the germ layers.
- The process of creating and growing an embryo from a zygote (zygotic embryogenesis) or a somatic cell is known as embryogenesis (somatic embryogenesis).
- An incredibly well-organized series of cell division, expansion, and differentiation takes place during embryo development.

Answer:
The positive charge of the histone proteins get reduced due to the process of histone acetylation, thus making the wrapping of DNA around the histones less tightened. The loose connected DNA afterward associates with the transcription factors for the articulation of the genes situated in that area.
Generally, when there is no requirement of gene anymore, the acetyl groups from the histones get withdrawn by the activity of histone deacetylase enzyme (HDAC9) that makes the DNA tightly wrapped and inaccessible again. In case, when less expression of histone deacetylase enzyme occurs, the process of deacetylation fails to take place. This indicates that within an immune cell, at the time of infection, the inflammatory gene, which was made available does not get re-wrapped firmly around the histones.
