Give an example for a cell fate determinant that is asymmetrically segregated into particular cells and explain what it does
Answer-Nematode Caenorhabditis elegans is an illustration for fate determinant which is asymmetrically segregated into particular cells.
An asymmetric cell division generally produces two daughter cells with peculiar cellular fates. It has symmetric cell divisions that leads to daughter cells which have equivalent fates. stem cells breaks asymmetrically which leads to two distinct daughter cells: one is an exact duplicate of the original stem cell and the second daughter formed to be categorised into a non-stem cell.

could someone explain this and give me a problem example
• Compute the determinant of a matrix (1by1, 2by2), and a matrix (3by3) by cofactor expansion along a row or a column for fixed row i, or det A=> aijCij j=1 det A= ij Cij, for fixed column j.
Question 5 20 pts A stem cell divides into two daughter cells. One of the daughter cells goes on to become a terminally differentiated cell. What is the typical fate of the other daughter cell?
Refer to “Chromatin dynamics in the regulation of cell fate allocation during early embryogenesis” paper (found by googling), and answer the following questions. 1. At what specific stage do blastocysts start to exhibit asymmetry? Are cells at this stage still totipotent? Why or why not? 2. Which transcription factors does trophoectoderm express? 3. Which transcription factors do the inner cell mass express? 4. Of the inner cell mass transcription factors, which of these is a “maternal effect gene”? 5. When examining...
How does differential gene expression control organismal development? All cells are differentiated early in development, and that determines the final fate of the cell. Epigenetic inheritance controls what genetic material ends up in each individual cell, determining its fate. Each cell contains different genes that are controlled by gene regulators and determine the final fate of the cell. Development is controlled by genes regulated in different ways in different cells and at different times during development.

Time it takes for a particular type of biological cell to divide into two cells is believed to follow a bell-shaped distribution with a mean of 30.2 minutes. In a lab study of 22 such cells, the average time to divide was 28.2 minutes with a standard deviation of 3.5 minutes. Does the study provide sufficient evidence to conclude that the mean division time for such cells is less than 30.2 minutes? Round to 3 decimal places if necessary. You...
