Homework Answers
Aneuploidy cells:
The cell in the human body from two haploid gamete and diploid
blastomeres having unique functions in the early human embryo and
malignant of aneuploid cells that promote embryo development.
Gametes is a cell that fuses with another cell during
fertilization.
Zygotes cells that result in fertilization between egg and
sperm.

Properties of human embryonic stem cells, developed from surplus embryos after in vitro fertilization, include: (A) can replicate themselves to provide a pool of stem cells (C) can be injected into a whole organism (human) without the risk of rejection (B) can be differentiated into other cell types Both A and B are correct All answers are correct

Cloning Human Embryonic Stem Cells Cloning is now possible by inserting a skin cell from a baby into an unfertilized human egg that has had its own DNA removed. This produces a blastocyte (an undifferentiated embry onic cell), which includes stem cells identical to the baby's. With this technique it is possible to make genetically identical embryonic stem cells from any cell in the human body. This would remove the need to harvest these cells from existing embryos. Theoretically these...

Describe the link between the EGF receptor and Ras During embryonic development, the ability of undifferentiated cells to become various different types of differentiated cells diminishes. Describe the abilities of cells to do this during different points in human development. What sorts of factors determine what a cell is to become? If a cell is removed from an 8-cell human embryo, what is the effect on the embryo? What can be done with the cell?

How does differential gene expression control organismal development? All cells are differentiated early in development, and that determines the final fate of the cell. Epigenetic inheritance controls what genetic material ends up in each individual cell, determining its fate. Each cell contains different genes that are controlled by gene regulators and determine the final fate of the cell. Development is controlled by genes regulated in different ways in different cells and at different times during development.

In gametogenesis in both human males and females: (Select all that apply.) diploid stem cells are the precursors to haploid gametes. secondary spermatocytes and secondary oocytes undergo both meiotic divisions in quick succession to produce mature gametes secondary spermatocytes and secondary oocytes form by meiosis from primary spermatocytes and primary oocytes. stem cells form during embryonic development and divide by mitosis. all primary spermatocytes and primary oocytes divide by meiosis.

Which of the following statements regarding embryonic stem (ES) cells are true? A. They can only generate a very limited number of cell types. B. They can theoretically give rise to all types of cells in an organism. C. They are highly specialized. D. They are pluripotent. E. Harvesting them from human embryos raises ethical and political issues.
