Front 1

identical twins (formed)

Back 1

-8 cell stage embroy splits in 2 and each develops
-need "reset" so they can give rise to cell types

Front 2

fraternal twins (formed)

Back 2

2 seperate eggs that are fertalized

Front 3

asymmetric cell division

Back 3

a cell divides to produce 2 cells that are different from each other

Front 4

transcription factors

Back 4

proteins that control transcription (expression of genes) by speeding up or slowing down production of proteins

Front 5

zygote

Back 5

-initial cell formed when a new organism is produced by sexual reproduction
-all cells are descendants from the zygote in a human
