1. B and D
Insulator blocked the gene expression . That's why 'B' gene expressed mRNA and produced protein help of promoter and enhancer but 'C 'gene didn't expressed properly. ' A' gene has insulator between enhancer and promoter so that it can't expressed protein . Insulator used as a blocking agent or barrier of gene expression. 'D' has enhancer and promoter after insulator so that was not issue to express the gene properly.So, only B and D effected by enhancer rest of effected by Insulator.

You are following the inheritance of three genes: A, B and C. A and B are on the same chromosome; C is on a different chromosome from A and B (for example; A and B are on chromosome 1 and C is on chromosome 4). Which option correctly represents the genotype of an individual who is heterozygous for all three genes? Select one: O a. AB/ab; C/c O b. A/a, B/b, C/c c. AaBbcc d. ABC/abc

You decide to make a construct that places the DNA between the
genes upstream to a reporter gene (GFP) in place of Gene 1. The
full-length construct has the correct expression pattern in
antennal discs. You then create several constructs that delete
sections of the upstream DNA and score them for expression. The
seven constructs are shown below; the black bars indicate the
region(s) deleted in each construct. The data table on the right
shows the expression results for each...
