Mammary cell Egg with nucleus removed The donor nucleus from the mammary cell and the maternal protelns within the enucleated egg Initlate development of the egg Into an embryo. The embryo Is transferred Into a surrogate ewe. Surrogate ewe Allow pregnancy to proceed. A lamb genetically Identical to the donor sheep Is then born. FIGURE 22.6 Protocol for the successful cloning of a sheep. Genes-Traits Dolly was genetically identical to the sheep that donated a mammary cell to create her. Dolly and the donor sheep were genetically identi- cal in the same way that identical twins are; they carried the same set of genes and looked remarkably similar. However, they may have had minor genetic dif- ferences due to possible variation in their mitochondrial DNA and may have ex- hibited some phenotypic differences due to maternal effect or imprinted genes.
Genetic Recombination
Recombination is crucial to this process because it allows genes to be reassorted into diverse combinations. Genetic recombination is the process of combining genetic components from two different origins into a single unit. In prokaryotes, genetic recombination takes place by the unilateral transfer of deoxyribonucleic acid. It includes transduction, transformation, and conjugation. The genetic exchange occurring between homologous deoxyribonucleic acid sequences (DNA) from two different sources is termed general recombination. For this to happen, an identical sequence of the two recombining molecules is required. The process of genetic exchange which occurs in eukaryotes during sexual reproduction such as meiosis is an example of this type of genetic recombination.
Microbial Genetics
Genes are the functional units of heredity. They transfer characteristic information from parents to the offspring.
