Zach uses an amoeba in a model of asexual reproduction. The first two steps of Zach's model are shown Which statement best explains what the final step of Zach's model will be? A. Two amoebas each with half of the original genetic information, because each receives half the genetic information from the parent

B. One large amoeba with two copies of identical information, because the genetic material is copied in reproduction

C. Two amoebas with identical genetic information, because each receives a complete copy from the parent cell

D. Four amoebas each with half of the original genetic information, because each will join with another amoeba create a new organism

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.
