Stem cells are important to development because they act as a blank
slate. The DNA from stem cells is replicated as seen with all living cells.
After mitosis, the new cells can differentiate into what the body needs
because the genes within the DNA may be turned on or off. There are
many factors that affect cell differentiation. Depending on these factors,
the proteins needed for gene expression are made from those specific
segments of DNA. Based on this information, select all the statements
below that are TRUE regarding this process.
All types of cells in a multicellular organism have the same DNA
Differentiation of cells may occur due to a difference in gene expression
Environmental factors such as temperature and light may have an influence on cell
differentation
Cell differentiation is influenced by how DNA is transcribed to RNA
