Genetics 4

Question 1

what does PCR stand for

Answer 1

polymerase chain reaction

Question 2

what is PCR

Answer 2

technique to make many copies of replicating DNA using altered bases
which are then analyzed using gel electrophoresis
the fragments are put in order to reveal the sequence of bases in the gene

Question 3

what are the steps to make a transgenic organisms

Answer 3

1. find the desired gene
2. cut the Dna of both organisms using the same restriction enzyme
3. paste the DNA from one organism into the DNA for the other using an enzyme

Question 4

why can we mix genes from different organisms

Answer 4

because all organisms use the same bases in their DNA so we can combine genes from different organisms

Question 5

what is the restriction to inserting genes into other organisms

Answer 5

genes can be inserted into any organism for which we know the genome for

Question 6

what is gene therapy

Answer 6

the process of changing a defective gene that causes a genetic disorder
the body will bring to correct the disorder using the new gene

Question 7

what is cloning

Answer 7

cloning is the production of a genetically identical organism from a body dell instead of a gamete(sex cell)
