When the genetic code is always the same how does one cell become a brain cell and another a skin cell?
While the DNA in one's cells may be the same, not all of the genes are active at the same time. Some genes code for proteins that regulate the expression of other genes,… for example. In addition, internal conditions in the cells during development of the embryo may affect the order in which certain genes are expressed as well. This differential gene expression results in the diversity of tissues we see.
That happens because all cells have a job and even if there the same they get a different job.
Brain cells are made from other brain cells, and skin cells are made from other skin cells. Cells are born to be what kind of cell they will grow up to be.
One strand of DNA is kept during the copy of DNA, while also a new one is added for a new strand, allowing it to become a double helix again.
mitosis is the process of 1 cell becoming 2 cells.
no. it should be 2 cells. the egg cell and the sperm cell
one cell can become one baby becuase it is in a seperate egg and it starts to grow and develop its organs
Through the process of Mitosis
Impossible. Each cell is made for a specific function. Skin cells cannot go to the brain and brain cells cannot break through the skull, and surface its way up to the skin.
It multiplies more than a million times every ten seconds- you see what i mean, don't you.
Four haploid cells are created from one diploid cell by the process of meiosis.

By influence of the environment (the uterus, and hormones), the fertilized ovum (single cell) replicates its genetic content and divides, resulting in two cells. These two cel…ls further replicate and divide into four, eight, sixteen, ... After multiple cycles of genetic replication and cellular division, further embryological development by cellular differentiation leads to formation of organs, and ultimately, to formation of a chicken! The more you know about the details in this process, the more incredible it seems that one cell can actually result in a living chick - or human being!
Sleeper cells are unrelated to human physiology. It is a group of people.
