How could scientists get chickens to increase the expression of the gene that regulates beak size?

Question

Quizplus · Accepted Answer

Transcription factors are regulatory proteins that bind to DNA and control the rate of transcription of genes. Increasing transcription factor binding to the promoter of the gene that regulates beak size would increase the expression of the gene, leading to larger beaks in chickens. Introducing a mutation into the gene that codes for amino acids or altering the structure of the gene would likely lead to a dysfunctional protein or gene product. Removing introns or increasing the size/number of exons would not necessarily increase the expression of the gene.
