Place the chromosomes of this organism onto the cell below such that the diagram accurately shows a cell from this organism in metaphase of mitosis. Note 1: Only place chromosomes you need. You don't need them all. Note 2: You can place the 'Blank Box' image if you don't think you need a chromosome at a particular position. Dashed line - the metaphase plate 1.In a human somatic cell (normal body cell) that is in G2, what would be true about chromosome number and structure? Check all that apply. Check All That Apply These cells would be considered haploid (n).These cells would be considered haploid (n). The chromosomes would be in the replicated state.The chromosomes would be in the replicated state. The chromosomes would be attached to microtubules at their centromeres.The chromosomes would be attached to microtubules at their centromeres. These cells would contain homologous chromosomes.These cells would contain homologous chromosomes. These cells would contain sister chromatids.These cells would contain sister chromatids.

- Only some cells derive from a mitosis event.. 1. Which statement is most correct regarding the difference between mitosis and meiosis? O Meiosis can produce any cell type, while mitosis can only make gametes (sperm/egg cells) * Mitosis essentially clones a cell (makes an identical copy), while meioisis is a ma O complex process that divides up a cell's set of chromosomes into gametes (sperm/egg cells) ODNA replication is required for mitosis but not for meiosis ODyads are seen in mitosis but not meiosis 2 What distinguichon honMatch the description on the left with the correct term on the right When the nuclear membrane dissolves andy the chromosomes appear Options: When the nuclear membranes reform and visible chromosomes go back to less coiled Prophase chromatin Metaphase Chromosomes line up along the midline of the Telophase cell Anaphase When sister chromatids separate and move to opposite sides of the cellYou are working with an animal species with a chromosome number of 2n = 4. One pair of chromosomes is telocentric and one pair is acrocentric. Draw and label a cell from this species at anaphase of mitosis.
- 1 3 4 Here is a replication fork during S phase of the cell cycle. DNA strands are labeled 1-4. After mitosis and cytokinesis is complete, One daughter cell will have strands 18&2, another will have strands 3&4 One cell will have 1&3, the other will have 2&4 Each of the strands (1-4) will be in a different cell. All four strands will end up in the same cell, and the other cell will have the complementary strands. Both A and B are equally likely.1. Assume that a cell is 2n=2 (diploid has two chromosomes, the same size). DRAW the following stages below. Use / for unreplicated chromosome and X for replicated chromosome. Use a metaphase plate that is vertical. For simplicity, do not indicate the nuclear membrane, spindles or that the chromosomes are decondensed (unwound) in interphase. Draw the chromosomes even if you would actually only see chromatin during interphase For reference this is Metaphase of MITOSIS Metaphase of MEIOSIS I Metaphase of MEIOSIS II one gamete a. d. b. G1 е. C. G2 f. X а. b. С. d. е. f. 2. Carefully analyze the following images. A a. Describe each as n= (1 or 2 "sets" of information is held on how many chromosomes). Also indicate how much DNA is in each compared to a respective gamete which has 1x amount of DNA) Ploidy (2n or 1n?) 1n_ # of chromosomes 2 amount of DNA 1x_cell type: 9) Label the figure below. Chromosome number: cytokinesis by: division type: А- В- С- D- E- the halves the number of chromosomes, and at the same time, stage. The result is 10) daughter cells event that causes genetic diversity takes place in called (n? 2n?). An organism with two of each kind of chromosome is said to be: (3) tetraploid (1) haploid (2) diploid (4) polyploid. In multicellular organisms, mitosis results in: (1) reproduction (2) growth and repair (3) sperm and egg production (4) fertilization.

- Which of the following statements is TRUE? O Interphase chromosomes are loosely compacted, overlapping, and intertwined with each other within the nucleus. O Interphase chromosomes are loosely compacted and do not associate with histones until the cell is preparing to divide. O Interphase chromosomes are also known as euchromatin. Condensed, metaphase chromosomes are also known as heterochromatin. O Radial loops in the condensing chromosome are formed due to interactions between 30 nm fibers and the scaffolding proteins of the nuclear matrix - producing the 300 nm fiber of the chromosome O None of these are TRUEYou would expect to find chromatin in which form during the Gap2 phase of the cell cycle? Replicated heterochromatin Chromatin in the same form as during metaphase of meiosis. Chromatin in the same form as during metaphase of mitosis Un replicated heterochromatin Replicated euchromatinThe structure that gives terminal : stability of chromosomes is Kintochore O Centromere and telomeres Centromere O telomere O
