The mechanism involved in maintaining patterns of gene expression in the daughter cells or cell memory is Asymmetric cell division.

Here's a step-by-step explanation:

1. Asymmetric cell division is a process in which a single mother cell divides into two daughter cells that are not identical. This is a crucial process in cell differentiation, where cells become specialized in their function.

2. During this process, the mother cell's cytoplasm is divided unequally. Certain molecules that determine cell fate, such as proteins and RNA, are distributed unevenly between the two daughter cells.

3. These molecules can influence the gene expression patterns in each daughter cell, leading to different cell fates. For example, one cell might become a nerve cell, while the other becomes a skin cell.

4. This mechanism is crucial for maintaining cell memory, as the gene expression patterns established in the mother cell can be passed on to the daughter cells. This allows the cells to remember their specific functions and continue performing them.

5. Therefore, asymmetric cell division plays a key role in maintaining patterns of gene expression in the daughter cells or cell memory.
