In a species of bird, the allele for the striped trait is recessive to the allele for the speckled trait. suppose that a coastal bird population has a striped phenotype frequency of and an inland population has a striped phenotype frequency of the two populations are isolated and in hardy–weinberg equilibrium. let represent the allele frequency of the coastal population and represent the allele frequency of the inland population. calculate the allele frequency for the striped allele for each population. round your answers to the nearest hundredth.

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.
