Transcription factor binding sites (promoter sequences) are named for their sequences. among these are what people cutely call the "cat box motif," which involves the nucleotides c, a and t in some arrangement that spells out cat or something like it, examples: caat, ccaatt, cata. identify two sequences that might serve as “cat box” promoter sequences.

Suppose a particular species of tulip plant has three alleles for the gene that codes for flower color. the cr allele produces red tulips, the cp allele produces purple tulips, and the cw allele produces white tulips. cr is dominant over cp and cw, and cp is dominant over cw. for each of the following crosses, determine the expected ratio of offspring for each flower color. cr cp x cp cw cr cw x cp cw 1 red: 1 purple : 0 white, 1 red: 2 purple: 1 white, 2 red: 1 purple 1 white, 1 red: 3 purple : 0 white, 2 red: 0 purple : 2 white, 2 red: 2 purple : 0 white
