Max discovered a beaker full of transparent liquid in the science lab. he hypothesized that since the liquid is transparent like water, it is water. he shared this conclusion with his friends. his friends questioned his conclusion, but max had no evidence to back his thoughts. what step did max miss in his scientific methods?

the correct answer: the index of refraction of the second medium is lower i tried this persons answer and it was wrong this person is lying

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.
