QUESTION 8 Match the stage of meiosis to its description. Watch for "cell" versus "cells". 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. Metaphase I the copies of the chromosomes (daughter chromosomes formerly known as sister chromatids) split apart and move towards the ends of two cells E. Anaphase I v the cell divides into two cells, chromosomes decondense F. Telophase I G. Interkinesis tetrads separate and homologous chromosomes begin to move in opposite directions in a cell H.…
Question 5 Review meiosis. This is a multiple answers question. Which statement is true about the meiosis? O Meiosis is preceded by the replication of chromosomes O In early prophase I, each chromosome pairs with its homolog and crossing over occurs O In anaphase I, pairs of homologous chromosomes separate O At the end of meiosis 1, the number of chromosomes is reduced by half and genetic variation is produced. O During Meiosis II, the number of chromosomes is reduced by half and genetic variation is produced.
Question 7 1 pts Which of the following statements is an incorrect description of the processes of mitosis or meiosis in a diploid organism?

QUESTION 7 Match the event that happens in meiosis with how we simulated it in this lab. gred and yellow bead strands of the same length that looked like an Jx attached to each other with magnets red and yellow bead strands moved together towards a pole instead of breaking apart and moving to opposite poles A. DNA replication B. tetrad formation bead strands could be arranged so that either the red or the yellow beads were above or below the middle of the cell C. crossing over single bead strands had another bead strand added to it attached by a magnet (ex. a long yellow strand had another long yellow strand added so it no longer looked like a single strand but more like an X) D. random alignment E. nondisjunction white paper was cut through F. cell division 4 yellow beads were popped off the bottom of a yellow strand and 4 red beads from an adjacent red strand and the opposite colors were joined (eg. yellow got snapped onto red and red onto yellow)
Question 41 Which of the following statements does BEST compare the processes of mitosis and meiosis? O Mitosis involves two division cycles and results in haploid gametes, while meiosis consists of one division cycle and results in a diploid daughter cell O Mitosis involves two division cycles and results in diploid daughter cells, while meiosis consists of one division cycle and results in haploid gametes. O Mitosis involves one division cycle and results in diploid daughter cells, while meiosis consists of tavo division cycles and results in haploid gametes. O Mitosis involves one division cycle and results in haploid gametes, while meiosis consists of two division cycles and results in diploid daughter cells.

Question 2 If a certain species has a DNA content of 5 picograms in each diploid cell's nucleus when the cell in in G1 of the cell cycle, what would be the expected DNA content (in picograms) of a diploid cell (from the same species) in mitotic prophase? Explain your reasoning. Consider ploidy changes and/or chromosome form changes, if applicable, when explaining your reasoning.
Question 3 If a certain species has a DNA content of 12 picograms in each diploid cell's nucleus when the cell in in G1 of the cell cycle, what would be the expected DNA content (in picograms) of a triploid cell (from the same species) in mitotic prophase? Consider ploidy changes and/or chromosome form changes, if applicable, when explaining your reasoning.
