|
|
|
each cell type contains only the active parts of the DNA needed for that cell type
|
|
|
each cell type has only one chromosome containing the DNA needed for that cell type
|
|
|
each cell has an identical copy of DNA with enzymes controlling the expression of specific genes, leading to a variety of cells
|
|
|
each cell has multiple copies of DNA that are affected in different ways by the environment to change the function of the cell at regular intervals
|
Detailed explanation-1: -The embryonic cells become specialized for a variety of functions. Which of these statements best describe how different cell types develop? each cell has an identical copy of DNA with enzymes controlling the expression of specific genes, leading to a variety of cells.
Detailed explanation-2: -Cell differentiation is critical during embryonic development. The process of cell differentiation results in the production of many types of cells, including germ, somatic, and stem cells. Cell differentiation is most directly regulated by: ATP.
Detailed explanation-3: -The cell types in a multicellular organism become different from one another because they synthesize and accumulate different sets of RNA and protein molecules. They generally do this without altering the sequence of their DNA.
