Video transcript

Hey, everyone. Let's take a look at this question. Together, blank occurs when the genes are activated or inactivated, blank. On the other hand starts when the cell synthesizes the tissue specific proteins from the activated genes. Is it answer choice, a degradation and differentiation. Answer choice B, initiation and transcription. Answer choice C determination and differentiation or answer choice D transcription and translation. Let's work this problem out together to try to figure out which of the following answer choices contains the two answers that fill in the blanks. So something that we know about genes is that certain genes are determined to become active or inactive through a process that is called determination. And this process of determination is when those certain genes are determined to become activated or inactivated. And from those active genes, cells synthesize the tissue specific proteins of active genes during a process that is called differentiation and differentiation is primarily the product of determination. Since determination determines when certain genes are activated or inactivated and differentiation starts when the cell synthesizes proteins that are tissue specific from those activated genes that were activated during determination. And so determination occurs when the genes are activated or inactivated. And differentiation starts when the cell synthesizes the tissue specific proteins from the activated genes. So that means that answer choice C is the correct answer because we know that determination occurs when genes are activated or inactivated. And differentiation. On the other hand starts when the cell synthesizes the tissue specific specific proteins from the activated genes. So answer choice C is the correct answer. I hope you found this video to be helpful. Thank you and goodbye.

Textbook Question

In this chapter, we have focused on large-scale as well as the inter- and intracellular events that take place during embryogenesis and the formation of adult structures. In particular, we discussed how the adult body plan is laid down by a cascade of gene expression, and the role of cell–cell communication in development. Based on your knowledge of these topics, answer several fundamental questions:

How did we learn about the levels of gene regulation involved in vulval development in C. elegans?
