Label the steps of transcription in order, beginning with step one. free rna nucleotides pair with the complementary dna nucleotides on one strand of dna. the mrna molecule breaks away as the dna strands rejoin. rna polymerase unzips the dna molecule.

1. RNA polymerase unzips DNA

2. Free RNA nucleotides pair with complementary DNA nucleotides

3. The mRNA molecule breaks away as the DNA strands rejoin.

Hope this helps!

1. step two

2. step three

3. step one

garbage disposal because lysosomes dispose of old cell parts like garbage disposals dispose of old food.
