Cell differentiation occurs when a single fertilized egg divides and its cells begin to specialize into different types. This process is guided by gene expression, where specific genes are activated or silenced in response to various signals, such as chemical cues from surrounding cells. As a result, one cell may express genes that lead it to become a brain cell, while another cell may activate genes that guide it to become a skin cell. This specialization allows for the formation of diverse tissues and organs within an organism.

What process is responsible creating distinct sets of proteins in skin cell compared to brain cell?
Gene expression is responsible for creating distinct sets of proteins in skin cells compared to brain cells.
Why are stem cells better than other cells for helping people?
Stem cells are undifferentiated, which means that they can become anything. A skin cell is only a skin cell, a nerve cell is only a nerve cell, and a skin cell can't do what a nerve cell does, or vice versa. But a stem cell can become either a skin cell or a nerve cell, or any other cell your body has.
Does cell division occur at the same rate in skin cells as in brain cells?
No, cell division rates can vary between different types of cells. Skin cells typically divide more frequently than brain cells. Skin cells are constantly replenishing and regenerating, whereas brain cells have a lower rate of division.
What nerve of the skin bring message to the brain?
The nerves that carry messages from the skin to the brain are called sensory nerves. These nerves transmit information about touch, temperature, pain, and other sensations from the skin to the brain for processing and interpretation.
How does the DNA in a turtles brain cell compare to that of a skin cell why are the cells different?
The DNA in a turtle's brain cell and skin cell is fundamentally the same, as both cells originate from the same genetic material. However, they differ in gene expression; specific genes are activated in brain cells that are not expressed in skin cells, leading to distinct functions and characteristics. This differential gene expression is influenced by the cells' unique roles in the organism, with brain cells primarily involved in processing information and skin cells serving protective functions. Thus, while the underlying DNA is identical, the way it is used by the cells results in their different identities and roles.
Skin cells have how many pairs of chromosomes?
Yes, any cell of an organism, whether it be a skin cell, brain cell, muscle cell, or other, has chromosomes. Humans have 23 unique chromosomes which come in pairs in every cell of their body.
What process is responsible creating distinct sets of proteins in skin cell compared to brain cell?
Gene expression is responsible for creating distinct sets of proteins in skin cells compared to brain cells.
Does the DNA in the skin cell have the same sequence of bases as the DNA in the brain cell of the same organism?
It is true thatÊthe DNA in the skin cell have the same sequence of bases as the DNA in the brain cell of the same organism. The sequence of the bases should be the same in all cells of an organism.

How does injuries on skin heal faster than injuries in the brain?
Injuries in the brain do not heal because brain cells cannot grow back. On the other hand body cells (skin) do grow back.
Is the brain the largest organ in the human body?
No, Your Lungs simply are the largest, PS: skin isn't a cell :P
Does a cell have a brain?
Yes and no. Cells have something which is called a nucleus. The nucleus is kind of like the brain. It tells the cell what to do and when to divide or split. The nucleus is usually in the middle of a cell. It is surrounded by the nuclear membrane. Around the nuclear membrane is cytoplasm. Cytoplasm has smaller microbes inside which carry out the duties the nucleus(brain) has given them. The protecting the cytoplasm is the cell membrane which is the outer shell of the cell or the skin.
How does the structure of an onion skin cell differ from other plant cells?
The structure of an onion skin cell differs from other plant cells in that it lacks chloroplasts, which are responsible for photosynthesis. Onion skin cells also have a unique rectangular shape and a thin cell wall compared to other plant cells.
What does the skin cell do?
the skin cell protects the skin
