Mitosis is the division that results in two “daughter” cells. Both of these daughter cells have the same number of chromosomes as the “parent” cell.
Mitosis consists of 4 phases: prophase, metaphase, anaphase, and telophase.
Prophase: the DNA is copied and the chromosomes pair up
Metaphase: the chromosomes line up in the middle of the cell
Anaphase: sister chromatids are pulled apart from each other towards opposite sides of the cell
Telophase: the cell begins to pinch in the middle and separates into two identical daughter cells
The answer is A. RNA polymerase will be making an mRNA using a single DNA strand as a template. So, for example if the DNA strand is AGGCAGC the mRNA strand will be UCCGUCG.
U= uracil which replaces thymine in mRNA molecules.
