It is required to determine if the DNA contains gene(s) and also to determine if the gene(s) are regulated. Enhancer sequences and their functions on the gene are shown in the table below. An enhancer binds an activator hormone and stimulates the transcription of a gene that it regulates. In this particular DNA, an enhancer located within 150 base pair from the start codon of a gene is a regulatory sequence for that gene Activator Hormone Gene function Enhancer sequence 5' -TAACCT- 3' 5' -TGGGCT- 3 5' -TCCCCT- 3 5' -TGTTCT- 3 5' -TCCAAT- 3' Gene for blood contamination antibody Gene for blood cloth Anti-cancer gene Gene for hair growth Anti-aging gene Determine (a) If the DNA sequence contain (b) The promoter sequence(s) and their location on the gene(s) (c) The mRNA transcript(s) (d) The amino acid chain produced by the gene(s) (e) If a gene is regulated in this DNA (f) The regulatory sequence and the location for a regulated gene (g) The function(s) of the gene(s) in the DNA from the information provided s gene(s)Explanation / Answer
