Question
Answer the following questions
(Problem 21a) The eyeless gene is required for eye formation in Drosophila. It encodes a homeodomain, a conserved protein domain containing 60 amino acids found in a significant number of transcription factors. What would you predict about the biochemical function of the Eyeless protein? The eyeless gene likely affects the expression of many transcription factors regardless of their DNA sequence. The eyeless gene likely affects the expression of many transcription factors and is DNA sequence-specific in its binding. The presence of a homeodomain likely indicates that eyeless selectively inhibits transcription factors expressed during eye formation.Explanation / Answer
Answer 21a The eyeless gene likely affects the expression of many transcription factors and is DNA sequence-specific in its binding.
Answer 22a Each region controls the expression of gene X in many tissue types, but the specific amino acid that has been mutated will determine if it is expressed in more than one tissue.
