were there any other experiments conducted when this type of engineering branch was emerging?
UNANSWERABLE
what is the purpose for each of the following important techniques used in genetic engineering To change the genetic makeup of cells what is the definition of this branch of science? Direct manipulation of an organism's genes using biotechnology. what are the steps involved to execute this engineering process? Either isolating and copying the genetic material of interest using recombinant DNA methods or by artificially synthesising the DNA. what are the materials and equipment needed to carry out this engineering process? The gene is separated by using restriction enzymes to cut the DNA into fragments to amplify up the gene segment, which can then be extracted through gel electrophoresis. what are some of the things manufactured using this technique? Has applications in medicine, research, industry and agriculture and can be used on a wide range of plants, animals and microorganisms. mention any one controversy about this branch of science. Concerns involve GM crops and whether food produced from them is safe and what impact growing them will have on the environment. who was the first scientist to initiate this engineering process? Stanley G. Weinbaum which year did he conduct the experiment to initiate this process? General concept of direct genetic manipulation was explored in Stanley G. Weinbaum's 1936 science fiction story "Proteus Island".

Genetic engineering [SEP] History
Humans have altered the genomes of species for thousands of years through selective breeding, or artificial selection as contrasted with natural selection. More recently, mutation breeding has used exposure to chemicals or radiation to produce a high frequency of random mutations, for selective breeding purposes. Genetic engineering as the direct manipulation of DNA by humans outside breeding and mutations has only existed since the 1970s. The term "genetic engineering" was first coined by Jack Williamson in his science fiction novel "Dragon's Island", published in 1951 – one year before DNA's role in heredity was confirmed by Alfred Hershey and Martha Chase, and two years before James Watson and Francis Crick showed that the DNA molecule has a double-helix structure – though the general concept of direct genetic manipulation was explored in rudimentary form in Stanley G.
