The genetic material of the sperm and egg then combine to form a single cell called a zygote and the germinal stage of development commences. The building up of these mechanisms therefore causes a shift in the relative volume of the nucleus and the cytoplasm. Tracing their cell lineage, scientists have started to determine some of the complex and epigenetic forces working on cell differentiation. They also form groups made of other, similarly specialized cells. The cells will divide and become more differentiated over time, increasing the . A further understanding of the close relation between the gene structure and the structure of the corresponding protein emerges from a study of the amino acid composition of the abnormal hemoglobins S and C. By comparing the amino acid sequence in the chains of normal hemoglobin A and of the abnormal hemoglobins S and C, it was found that the latter two differ from normal hemoglobin only in one amino acid. Stem cells which can differentiate into entire organisms are known as embryonic stem cells and are said to be totipotent. _____________ determine how cells are differentiated.

The estimate may be made even more exact if chemical substances and not morphological parts are taken into consideration. We have seen that the substitution of only one amino acid residue in the chain of human hemoglobin not only leads to a distinct morphological expression, in the shape of the red blood corpuscles, but also changes the metabolism of the whole organism. Within the first few days after fertilization takes. When does cell differentiation occur? As the tissues continue to form, some cells begin releasing hormones, or chemical triggers which signal various cells to react. A similar mechanism is known to produce the endocrine cells of the pancreas and the goblet cells of the intestinal epithelium. It also takes place in adult organisms during the renewal of tissues and the regeneration of missing parts. It is by the process of cell differentiation, that embryonic cells are changed to specialized cells. Where in somatic cells does mitosis occur?
