Created by StemPy LabThe figure shows the DNA content of one cell against time, through one cell cycle that ends in mitosis. The organism has . In which segment is the DNA replicated, and how many chromosomes does the cell have early in segment R, in G2 phase?
← All Quizzes
← A diploid organism has 2n chromosomes, and its cells hold 2C of DNA in G1 phase. Match each cell in List-I with its chromosome number and DNA content in List-II. List-I (Cell) A. A body cell in G1 phase B. A body cell in G2 phase C. Each cell of the dyad formed after telophase I D. Each cell formed at the end of meiosis II List-II (Chromosomes and DNA) I. n chromosomes and 1C of DNA II. 2n chromosomes and 4C of DNA III. n chromosomes and 2C of DNA IV. 2n chromosomes and 2C of DNAAssertion (A): Crossing over leads to recombination of genetic material on the two homologous chromosomes.
Reason (R): Crossing over takes place between the sister chromatids of one chromosome, during zygotene. →
