Laboratory research to advance knowledge and their use in the real world March 1 2014 Alice Y Cheung HenMing Wu Professors Biochemistry and Molecular Biology Dept Umass Amherst Yanjiao Zou Postdoctoral Associate. Learning Objectives:. Explain cloning.. Explain genetic engineering.. Analyse the advantages and disadvantages of cloning and genetic engineering.. Cloning. Clone. = an individual produced through asexual reproduction that is genetically identical to the parent. Natural selection acts on phenotypic variations in populations. Enduring Understanding 1A. Change in genetic makeup of a population over time is evolution. Environments change and act as selective mechanisms on populations.. Essential idea: Biologists have developed techniques for artificial manipulation of DNA, cells and organisms.. There are a number of key techniques involved in the analysis of DNA and gene transfer. The image above shows nuclear transfer, the key step in cloning by somatic cell nuclear transfer. Dolly the sheep was the first success clone using this technique of direct cell manipulation. SCNT remains a key part of genetic engineering as it allows patient specific embryonic stem cells to be created, a key step in the application of gene therapies in a patient.. You can compare dogs of every breed imaginable! . There is an enormous range of characteristics that are the result of . genetic variation. . . The differences among breeds of dogs are so great that someone might think that many of these breeds are different species. . You can compare dogs of every breed imaginable! .

Mendel discovered the principles of inheritance with experiments in which large numbers of pea plants were crossed. Gametes are haploid so contain one allele of each gene. Two alleles of each gene separate into different haploid daughter nuclei during meiosis. Fatal genetic . d. isorders . No cure. 1 in 3 infant deaths are . from genetic disorders.

Tissue culture is a process that involves exposing plant tissue to a specific regimen of nutrients, hormones, and light under sterile, in vitro conditions to produce many new plants, each a clone of the original mother plant, over a very short period of time. Natural SELECTION. Definition. : Breeding two compatible species to create an offspring, which may or may not have the desired traits.. FACTS:.
