Gene Splicing Lab interrogative 1 DNA is made up of two separate strands of base sequences. The analogous sequence is found on some(prenominal) strands, but running in opposite directions. What word describes this characteristic? Palindrome Question 2 What does the term ruttish ends refer to in gene splicing? When you splice a percentage of DNA with a restriction enzyme, and want to insert the new gene, the mucilage that holds the two pieces together be the complementary color bases, or sticky ends. Question 3 What is a plasmid? How is a plasmid used in gene splicing? A plasmid is a circular subdivision of DNA with an origin of replication.It can be duplicated and serve as an addition to the main bacterial chromosome. Question 4 What types of vectors are used to drop DNA from one species into the DNA of another species? Give examples. Generally plasmids and viruses, although defenseless DNA is a possible source as well. Question 5 What is a transgenic organism? Give examp les. Organisms that contain dna from another organism. it is a type of gmo, or genetically circumscribed organism. Ex genetically modified crops, transgenic cows that produce different milk, mice with different genesQuestion 6 Why is it immanent that the selfsame(prenominal) restriction enzyme be used to cleave (cut) the DNA of both organisms used to create a transgenic organism? The restriction enzyme cuts in specifc sites on the DNA, for example complementary strands. A and T or C and G. So only with the same enzyme at both the DNA of organisms in places where the complementary base pairing can be cut, is used as the same enzyme enzyme, the DNA will be cut for example. at A and T on both the organisms the opportunity to tie the organisms at these sites via H-bridges as complementary bases.Therefore, it is allowed to bind the two organisms form a transgenic organism Question 7 Are there any factors other than technical ones that might retard or even prevent the use of bioengi neering? There are many social factors that will impede the progress of bioengineering. In the matter of agricultural bioengineering, some people are frightened that bioengineered food would be less healthy. Bioengineered crops will also decrease the biodiversity of our food, making it more temptable to disease (ergo famine). Also, genetically engineered crops will give developed nations a broad advantage over third world in food production.
