Which of the following are usually identical between a lung cell and a brain cell, from the same person, assuming that they are normal (non-cancerous) cells? Circle your choice(s).
a. Size b. Shape c. Specific proteins found in the cell d. Specific genes in the cell’s genome e. Which genes are expressed f. Which parts of the DNA are methylated g. The specific DNA sequence of chromosome 12 h. All of the above i. None of the above
I said only D and G because all cells have the full genome. The difference between cells is how the these genes are expressed. All of the other options are results of different amound of gene expression. Is this the correct thinking?
