For the next group of questions consider a diploid cell from a eukaryotic organism with a total of ten chromosomes. After one round of the cell cycle is complete you observe a total of four daughter cells. During this cell division occurred and the resulting daughter cells are. mitosis; haploid with ten total chromosomes each mitosis; diploid with five total chromosomes each meiosis; diploid with ten total chromosomes each meiosis; haploid with five total chromosomes each Before the cell divided,...

Draw a diagram showing the movement of chromosomes within the cell during mitosis for a 2n = 4 organism (i.e., a diploid organism with two chromosomes like the one pictured on the right). Your diagram should include: 1.1) Labels of each phase of the cell cycle. 1.2) Labels indicating where A) DNA replication occurs, B) checkpoints occur, and C) mutations occur. 1.3) For each phase, label the location of the alleles. 1.4) An expanded section for mitosis with the following...

1. NMR researchers have an E. coli culture growing in a medium containing 15NH4C1. By accident, they switch to a medium containing 14NH4Cl. This culture environment continues for three generations (an 8-fold increase in population). What will be the molar ratio of hybrid DNA (1-N- 14N) to light DNA (14N-14N) at this point? Show how you came up...
