Singular versus plural is a clue that will help you pick the right roman numeral. homologous chromosomes line up next to each other as tetrads along the mid- line of the cell DNA condenses, tetrads form as homologous chromosomes come together and exchange DNA parts in crossing over, nuclear membrane disintegrates A. Early Interphase B. Late Interphase one of each homologous pair reaches the end of the cell, new nuclear membranes form, and the cell membrane begins to pinch in C. Prophase I v DNA condenses in two cells, nuclear membranes disintegrate D.
