Check all the examples that would be considered an APPROPRIATE use of biotechnology. A. Selective breeding to improve milk production in cows.

B. Genetic engineering of a virus to create a biological weapon.

C. Use of genetic modification to produce laboratory mice with D. Alzheimer's disease.

E. Use of genetic modification to produce a superior race of humans

F. Use of DNA evidence to free someone wrongfully convicted of murder.

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
