1
Q

Define cell differentiation?

A

The process by which cells become specialised for different functions. All cells contain the same genes but different genes are switched on and off in each of the specialised cells. Genes turned on will make particular sections of mRNA and particular proteins.

Q

Through cell differentiation some cell functions have been lost, this occurs how?

A
  • chemicals cause some genes to become activated
  • mRNA is only transcribed from active genes
  • translated into proteins, the protein modify cells
  • result in a specific function so a specific cell type
