15) Restriction length fragment polymorphisms refer to?
A) variation in the numbers of DNA repeats
B) variability in the sites recognized by restriction enzymes
C) differences in the DNA sequence of restriction fragments
D) A-C are all true
16) VNTR's occur in
A) eukaryotic cells
B) prokaryotic cells
C) both A & B
D) neither A nor B
17) The production of recombinant human insulin and growth hormone are examples of biotechnology. This is accomplished by
A) Inserting the insulin gene in E. coli
B) Injecting insulin into a diabetic person
C) Injecting insulin in a mammalian cell culture
D) Inserting the insulin gene in a diabetic person's pancreatic cells
Answer (1)
RFLPs refer to the variability in DNA cut sites recognized by restriction enzymes, while VNTRs primarily occur in eukaryotic cells. The production of recombinant insulin is achieved by inserting the insulin gene into E. coli. These concepts are fundamental in genetic analysis and biotechnology applications. ;
