How is nuclear transfer achieved for cloning? The nucleus of a sperm cell is replaced by the nucleus of a specialized cell, such as a nerve cell. The nuclear DNA is sent through the process of PCR. Embryonic stem cells are programmed to grow into specific tissues. The nucleus of an egg is replaced by the nucleus of a specialized cell, such as a skin cell. Question 2 (1 point) A fetus that results from reproductive cloning will be __________. genetically identical to the donor animal grown from embryonic stem cells from a donor animal able to develop to term without a recipient animal genetically identical to the recipient animal

What does the process of somatic cell nuclear transfer involve and how is it used to create cloned cells? What are three positive and negative aspects of cloning both scientifically and morally? Also, discuss if it is a good use of science and will benefit mankind or whether you believe it is unethical and should no longer be pursued. P.S. You can expand your discussion outside of therapeutic cloning if you wish.

During organismal cloning via nuclear cell transfer, what two different sorts of cells are used? Very briefly (in a phrase or short sentence), describe what each provides for the process of cloning. Cell: Provides What are the two techniques that can be used to accomplish nuclear cell transfer?

Although several different mammalian species have been cloned, the efficiency of this process is extremely low. Often tens or even hundreds of oocytes must be implanted with donor nuclei to obtain one healthy live birth. Many researchers believe the difficulties with cloning reside in the epigenetic modifications, such as DNA and histone methylation, that occur within various cells during an individual's life. How do you suspect such modifications might affect the success of an experiment such as that depicted in Figure $12.32 ?$
