Video transcript

Hey everyone, let's take a look at this question together. What happens during cleavage in animal development? So let's recall what we know from previous content about the development of animals. And so when we're talking about that, we're talking about cell division and another term for cell division and animal cells is called mitosis. And so the cleavage part of mitosis is when we have that one parent cell that gets split up into two identical daughter cells, so that split, another term for it is cleavage. So we're talking about the split of the one cell into two cells during mitosis or answer choice C. Because answer choice C refers to when you have the one cell embryo and it undergoes that my topic division or the cleave of the parent cell into two identical daughter cells. I hope you found this video to be helpful. Thank you and goodbye.

Textbook Question

The following predictions ask you to consider how genetic regulatory cascades provide positional information. Select True or False for each statement. T/F Mutation of a gene at one level of a regulatory cascade will affect the expression of genes at all levels of the cascade. T/F Mutation of a gene that is expressed later in a regulatory cascade will affect a smaller region of the body than mutation of gene that is expressed early in the cascade. T/F In the regulatory cascade used by Drosophila, a gene at one level of the cascade will be controlled only by genes at the level immediately above it. T/F Genes that control the largest regions of the Drosophila embryo are not transcribed in the embryo.
