Harry Potter speaks parseltongue(he can talk to snakes). Dumbledore explains that this is because harry expresses a gene than can regulate the expression of multiple language genes. based on what you learned in cell biology class, give an example of an enzyme that this gene could code for and explain in a line, how this enzyme could regulate gene expression?

Expert Answer

Step 1

Language is an example of a trait that is learned and developed throughout a lifetime. Language is a form of communication. Parseltongue is a language of serpents which is a hereditary trait present in Harry. FOXP2 is a language gene that encodes a protein called forkhead boxP2. FOXP2 is present on the 31st position of the seventh chromosome.  So, FOXP2 gene is responsible for speech and language perception. The protein boxP2 is a “transcription factor”, which means that it regulates the activity of other genes. Forkhead domains are the regions on these genes where the boxP2 protein attaches to the DNA that could regulate multiple language genes.

Step 2

It is uncertain that the forkhead boxP2 protein regulates hundreds of genes, although only some of its functions have been recognized. The forkhead boxP2 protein remains active in the brain, both before and after birth. It is involved in synaptic plasticity, which means the ability of connections between neurons or synapses to change and adapt to experience over time. Synaptic plasticity is essential for learning and memory. The forkhead box P2 protein is essential for the norma...
