To define: The term epigenetics.

Concept introduction: All the cells in an organism consist of similar DNA, but the cell types and their functions vary because of differential gene expression. It results due to the inheritance of genetic and non-genetic information.

Expert Solution & Answer

Explanation of Solution

The inheritance which occurs without any alteration in the genetic sequences is known as epigenetics. The term ‘epigenetic’ means ‘in addition to change in nucleotide sequence’. It leads to the alteration of gene activity that can be transmitted to daughter cells. There are three major epigenetic modifications referred to as histone modifications, DNA methylation, and RNA-based mechanisms. These regulate gene expression at the transcription level.

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.
