Answer:
DNA
Explanation:
The nucleus is a central placed organelle in eukaryotic cells. It is said to contain the "blueprint of life" known as the DNA. The DNA is a structure located in the nucleus of the cell that encodes information necessary for the growth and development of the organism.
This information encoded by the deoxyribonucleic acid (DNA) of the cell includes how the organism will reproduce, hence, DNA is called the blueprint of life.
Explanation:
In the early days of development, in an embryo, the cells are pluripotent and can differentiate into any kind of cell of the organism. As the embryo develops, autocrine and paracrine signaling between the cells of the embryo causes the cells to migrate to particular regions of the embryo and begin differentiating into respective parts of the organism. This signaling causes differential silencing of particular genes of the cells depending on the type of cells they will differentiate into. As the embryo develops into a fully grown organism, these cells lose potency (except for stem cells) and become fully differentiated into respective limbs or organs of the organism.
