Society expects scientists to follow ethical practices and meet many ethical standards. Which is an example of one of those ethical standards?
*
• Use all the data that was truly observed, not partial data that is expected or desired,
skewing results.

• Publish experimental results only if they agree with current theories or public opinion.
If they don't agree then its a waste of time.

• Investigate only the events that affect people's lives or livelihoods since that is the
only way to make money

• Continue the procedure of an experiment or investigation under all circumstances,
even if living things are being harmed in the process

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.

bradykinin is a physiologically and pharmacologically active peptide of the kinin group of proteins, consisting of nine amino acids.
