The hunchback gene contains a 5′ transcriptional regulatory region, a 5′ UTR, a structural region (the coding sequences), and a 3′ UTR.a. What important sequences required to controlhunchback gene expression are found in the transcriptional regulatory region of hunchback?b. What sequence elements that encode specific protein domains are found in the structural region ofhunchback?c. Another important kind of sequence is located inthe 3′ UTR of the hunchback mRNA. What mightthis sequence do?
Gene Interactions
When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of another gene, i.e., a single gene controls each of seven characteristics considered, but the complex contribution of many different genes determine many traits of an organism.
Gene Expression
Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.
The hunchback gene contains a 5′ transcriptional regulatory region, a 5′ UTR, a structural region (the coding sequences), and a 3′ UTR.
a. What important sequences required to control
hunchback gene expression are found in the transcriptional regulatory region of hunchback?

hunchback?
c. Another important kind of sequence is located in
the 3′ UTR of the hunchback mRNA. What might
this sequence do?
