Chapter 18, Problem 27P
Summary Introduction

a.

To determine:

The important sequences that are required to regulate the hunchback gene expression that is found in the transcriptional regulatory region of the hunchback.

Introduction:

The genes are the sequence of nucleotides that are present on the chromosomes and encode for a specific protein that plays a crucial role in the functioning of the different processes in an organism. The gene is located at specific gene loci and can be structural or regulatory in nature.

Summary Introduction

b.

To determine:

The sequence elements that code for specific protein domains that are found in the structural region of hunchback.

Introduction:

The genotype is the genetic constitution of the organism, while the phenotype refers to the external characters visible in an organism. The alleles are the contrasting forms of a gene, and one of them is dominant, and the other is recessive.

Summary Introduction

c.

To determine:

The significant sequence that is present in the 3’ UTR of the hunchback mRNA and the importance of the sequence.

Introduction:

The two stages of protein synthesis are transcription and translation. The transcription is the process where the DNA is converted into the mRNA by the action of DNA polymerase. A single strand of the DNA works as a template and leads to the formation of an mRNA molecule that is formed inside the nucleus. This mRNA is then transported into the cytoplasm where it is converted into protein chains through the action of tRNA and ribosomes.

If using animals in medical experiments could save human lives, is it ethical to do so? In your answer, apply at least one ethical theory in support of your position.
You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?
You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.
