Question

if your heart cells and brain cells have the same genes, why do they function differently?
thanks guys :)

Answer 1

despite the DNA being the same in every cell, after initial multiplication of the zygote, according to the different conditions being given to the cells which are the same, they develop differently and form different specialised cells, initially the specialization in a zygote is little but increases in complexity after more different surrondings are created by the initial specialization. (different types of initial surroundings can be a cell in contact with amniotic fluid and some other similar cells AND a cell completely surrounded by the same cells.) Thus different part of the DNA are expressed and heart and brain forms in different areas. Every cell in the body has the potential to become any other cell before specialization but due to conditions given to those particular cells, they form only the specific ones.

Answer 2

The entire human body originates from just one cell, the one that is formed when sperm meets egg during fertilization. Upon fertilization, the cell quickly multiplies until a more substantial mass is formed. At an early stage, these are called stem cells -- cells that do not yet have a specific function. Later on, the DNA tells each cell what its particular role will be -- which particular part of the body it will become. A more concrete example for this would be gender differentiation. Studies have shown that parts of the male and female reproductive organs come from the same types of cells, and the X and Y sex genes determine what will be formed from these cells. The presence of abnormalities in the sex genes, such as having XXY chromosomes (an extra one) will create physical mutations such as uncertain gender or mixed physical characteristics.

Back to your heart and brain cells, each one has been assigned differently by the DNA, so they form into different types of cells to perform different functions.

Answer 3

All the cells of your body contain the same DNA code (except the sperm and egg, which have half of a copy). Cells become differentiated (specialized) in their courses of development so that the functions that are necessary for the cell type are the only functions activated.

It's kind of like a computer program, such as Windows. It has a lot of code, but only certain parts of it are needed for each application.

Hope this over-simplification helps!

Answer 4

to put it in simple terms, when you are born, your cells start to specialize. so, heart tissue and muscle cells are told to pump blood throughout your body, while brain cells begin making connections with each other to expand your capability of learning as a baby.

this is why some scientists want to experiment with a baby's umbilical cord blood because it is chalk full of stem cells. These stem cells, unlike the ones found in the heart and brain, have not been specialized yet, so they can be "created" to fit any function.

Also: FFF. This means FormFitsFunction. The brain cell must have a different form than the heart cells because the brain has a different function and must make connections in order for your body in iits entirety to operate together cohesively.

good luck,

Answer 5

The different cells in the body perform different functions as they undergo cell differentiation,a process whereby cells develop certain characteristics to carry out their jobs effectively and efficiently.Brain cells is basically sending messages out to tell what the other parts of the body should do while heart cells help to beat the heart and pump blood to all other parts of the body

Answer 6

heart and brain have same genes but they have different combinations that is why they work differently

Answer 7

Well, your heart only pumps blood through your body while your blood cell help to fight of germs and bacteria.

Answer 8

nope, you've already named it.. "brain" cells help the brain and "heart" cells help the heart.. in short, since they're just cells, they're part of the organ that you've mentioned.

Answer 9

no.
