We will be looking at and discussing the ethical and biomedical aspects of both Embryonic and Adult Stem Cells.. An embryo is a . multicellular. . eukaryotic. organism in its early stages of development. In humans, an embryo is carried in the uterus.. I. n humans, the embryo is a developing organism until the first eight weeks, after which it is called a fetus until birth. . Specialisation. Learning Objectives. Learn about totipotency of cells.. Learn about when totipotent cells are present and what their rol. e is.. Learn how these cells can lose their totipotency.. Learn about . From Egg to Embryo. A. Terms. 1. Pregnancy – events occurring from the time of fertilization (conception) until the infant is born. 2. Gestation period – extends from the last menstrual period until birth (280 days). Organism DNA. 1a. Some of the strongest evidence for evolutionary relationships comes from studying the DNA of different organisms.. 1b. The fact that all organisms use the same DNA molecule to code for genetic information suggests that these organisms share a distant ancestor.. Saha. Department. of Zoology. University. of . Rajshahi.
