Which of the following is one major difference between the process of transformation in a bacterial cell and a yeast cell?
1) Exogenous DNA must be transported past the cell wall of bacteria, but there is no cell wall in yeast.
2) Exogenous DNA must be taken into cytoplasm and then the nucleus of the yeast cell, but only needs to be taken into the cytoplasm of a bacterial cell.
3) Bacteria are much smaller than yeast, so it is harder for them to take up exogenous DNA.
4) Yeast have nucleases that can easily degrade exogenous DNA, but bacteria do not.
