The peppered moth population in a locality has light and dark moth varieties. the tree barks in the locality are covered with light-colored lichens. how would the population of the two moth varieties change over time? (3 points) dark moth population increases as they are preyed upon less frequently light moth population increases as they are preyed upon less frequently dark moth population decreases as they blend in with their surroundings light moth population decreases as they blend in with their surroundings

the answer would be b.) the lighter moth population increases as they are preyed on less frequently.

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.

looks like the answer is     c     to me!
