Interphase. • A single strand of DNA serves as a template for a new strand. The mitotic spindle checkpoint occurs at the point in metaphase where all the chromosomes should have aligned at the mitotic plate. Genomic DNA preparations tends to be more reproducible than RNA preparations, because the representation and relative abundances of the individual RNA species of an RNA pool are harder to control and can vary substantially, depending on the conditions of the cells or tissues used to produce the RNA pool.
