What would you expect the difference to be in the rate of diffusion of vinegar (molecular weight about 60) compared to oxygen (molecular weight about 32)?

Vinegar has slower rate of diffusion due to higher mass.

Explanation:

The rate of diffusion in vinegar is slower than oxygen because of the higher mass of vinegar. Vinegar has molecular weight about 60 while on the other hand, oxygen has molecular weight about 32 so vinegar has more weight than oxygen which causes slow diffusion of vinegar from one place to another as compared to oxygen whose rate of diffusion is higher due to its lower weight.

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.
