what are stem cells?
stem cells are unspecialised, and they are found in the human embryo and in adult bone marrow. they can chnage into differnet type of body cells, nerve cells, muscle cells. they differentiate.
1 of 6
what can embryonic stem cells and adult bone marrow stem cells turn into?
*layers of cells in the embryo differentiate into all the cells the bosy needs. *stem cells in adult bone marrow can change into other types of cell, e.g. blood cells.
2 of 6
what could the stem cells that have been differentiated be used for?
the cells formed could then used to treat conditions such as paralysis, e.g by differentiating into new nerve cells.
3 of 6
who was mendel and what did he do?
was a monk who worked out how characteristics were inherited. medel was the first person to suggest the idea of seperately inherited 'factors'. it took a long time for Mendle's idea to be accepted.
4 of 6
why did it take a long time for Mendel's idea to be accepted?
because scientists didnt know about chromosomes and genes until after he died. Mendle's 'factors' are now called genes. genes are found in the chromosomes.

what are chromosomes made of?
DNA which is a very long molecule with a double helix structure.
