Summary Introduction
To review:
Some of the potential uses of cloning in animals as well as in humans.
Introduction:
Cloning is the process of developing genetically identical replica (also known as a clone) of cells, tissues or an organism. It is considered as of two types: therapeutic cloning and reproductive cloning. The cells (either genetically altered or without any alteration in their genetic makeup) from an individual are grown into organs for transplantation in case of therapeutic cloning. On the other hand, nuclear transfer is used in reproductive cloning to clone an organism.

- With the use of well-illustrated diagrams, reconstruct the entire cloning process by explaining different stages of the cloning process that involves the following:a. Isolation of target DNA fragments (often referred to as inserts)b. Ligation of inserts into the plasmid, creating recombinant molecules c. Transformation of recombinant plasmids into bacteria or other suitable host for propagationd. Screening/selection of hosts containing the intended recombinant plasmid. For this stage(d), discuss the importance of a second marker that can be used for screening of genomic DNA for colonies containing the pka-1 under the principle of insertional inactivation. This should be properly explained using all the attributes of the plasmid described above.arrow_forwardWhat is the main moralproblem about the cloning ofhuman individuals?arrow_forwardList all steps involved in a cloning workflow.
