Question

2 points In pea plants, one copy of the purple allele is enough to produce purple flowers in heterozygous plants. The purple allele is therefore and this makes it over the white allele. QUESTION 13 2 points In individuals with Sickle Cell Disease, only the adult form of hemoglobin carries a mutation in the myoglobin subunit. A potential therapeutic approach is to reactivate the expression of fetal myoglobin, which is normal and would reverse the disease. Which of the following steps is most likely to succeed in promoting transcription of fetal myoglobin in adult cells? Altering the expression of transcription factors to redirect the enhanceosome to the fetal gene promoter Removing the adult myoglobin promoter completely O Adding a different RNA polymerase Adding a second locus control region (LCR) closer to the fetal gene
