Textbook Question
Chapter 11, Problem 8TYK
You obtain an egg cell from the ovary of a white mouse and remove the nucleus from it. You then obtain a nucleus from a liver cell from an adult black mouse. You use the methods of nuclear transplantation to insert the nucleus into the empty egg. After some prompting, the new zygote divides into an early embryo, which you then implant into the uterus of a brown mouse. A few weeks later, a baby mouse is born. What color will it be? Why?

Scientists have cloned some animals by injecting a nucleus from an early embryo into an enucleated egg cell. Does this outcome demonstrate that genetic material is not lost during development? Why or why not?
In the tracking chromosomal DNA movement through mitosis experiment, how many chromosomes did each of your daughter cells contain? Why is it important for each daughter cell to contain information identical to the parent cell? How often do human skin cells divide? Why might that be? Compare this rate to how frequently human neurons divide. What do you notice?
In recent years, techniques have been developed to clone mammals through a process called nuclear transfer, in which the nucleus of a somatic cell is transferred to an egg cell from which the nuclear material has been removed . Research has demonstrated that when a nucleus from a differentiated somatic cell is transferred to an eggcell, only a small percentage of the resulting embryos complete development, and many of those that do die shortly after birth. In contrast, when a nucleus from an undifferentiated embryonic stem cell is transferred to an egg cell, the percentage of embryos that complete development is significantly higher (W. M. Rideout, K. Eggan, and R. Jaenisch. 2001. Science 293:1095–1098). Propose a possible reason for why a higher percentage of cloned embryos develop successfully when the nucleus transferred comes from an undifferentiated embryonic stem cell.

- a. Manually, using a pencil, draw a cell in anaphase II from an organism in which 2n = 2 and each chromosome is metacentric. b. Given that each G1 nucleus from this organism contains 16 picograms of DNA, how many picograms of chromosomal DNA would you expect in the cell shown here?arrow_forwardOne important biological effect of a large dose of ionizing radiation (like X-rays) is to halt cell division. How does this occur? To answer this question, state the name and role of 2 specific and important proteins involved in the process. What happens if a cell has a mutation that prevents it from halting cell division after be irradiated? Be specific and detailed. An adult human who has reached maturity will die within a few days of receiving a radiation dose large enough to stop cell division. What does that tell you about cell division? In addition, name 2 different/unique cell types that would be primarily affected.arrow_forwardIn the mitosis experiment, in what stage were most of the onion root tip cells in?
