1 bleul variation is accomplished. Crossing over-Does it occur? If so, name the stage it occurs. 2. Mitosis is best described as a. cell division of reproductive cells. b. cell division of somatic cells into two diploid daughter cells. c. unequal division of the cytoplasm. d. cell division resulting in 4 haploid cells. Matching: Match phases of the mitotic cycle with characteristic event. 3. Interphase a. formation of cleavage furrow or cell plate 4. Prophase b. chromosomes line up along...
Examine the onion root tip slide images on the following pages. There are four images, each displaying a different field of view. Pick one of the images, and count the number of cells in each stage. Then count the total number of cells in the image. Record the image you selected and counts in Table 2. Calculate the time spent by a cell in each stage based on the 24 hour cycle: Hours of Stage = 24 x Number of...

Question 1: The cell cycle has these stages A. GI, S, G2, M B. GI, S, BI, CL C. GI, S, G2, CI D. S, G2, NI, MI Question 2: During interphase, the following occurs A. Sister chromatids separate. B. Chromosome duplication takes place. C. Chromatin becomes tightly coiled. D. The mitotic spindle forms. Question 3: The correct sequence of stages of mitosis is A. prophase, metaphase, anaphase, telophase B. telophase, prophase, interphase, anaphase, metaphase C. interphase, anaphase, prophase, metaphase, telophase B. metaphase, prophase, anaphase, telophase Question 4: Human cells contain 23 pairs of chromosomes A....
Suppose that in an experiment you observed 113 cells in interphase, 24 cells in prophase, 9 cells in metaphase, 12 cells in anaphase, and 3 cells in telophase stages. If the complete cell cycle (i.e. G1+S+G2+mitosis; see Figure 1-2 of the Lab Manual) requires 24 hours, calculate the average duration of each stage in the cycle. Show all calculations. QUESTION 1 OF 10 Please read Chapter 1 of the Lab Manual and the relevant Power Point lecture in detail, and...
Interphase Melosis 1 Draw in the chromosomes for each stage of Meiosis. Your cell has a diplod # of 6 (haploid # of 3). Use two contrasting colors for your homologous chromosome pair. Prophase 1 Metaphase 1 Anaphase 1 Telophase 1 Melosis 2 Prophase 2 Metaphase 2 Anaphase 2 Telophase 2 4 daughter cells
1. If the amount of DNA in a somatic cell equals C during G1 of interphase, how much DNA is present in the cell during each phase of mitosis and meiosis? (2pts) Anaphase Telophase Cytokinesis Prophase 20 Metaphase T Mitosis Meiosis 1 Meiosis 2 2 Define the three things that are responsible for genetic variation and explain how they lead to genetic variation (1.5pts)
5. For this part of the lab you will be observing a whitefish blastula under the microscope. A blastula is a developmental stage in many animals. It occurs shortly after fertilization and the formation of the zygote. It is the “ball of cells” stage of development, where cells are dividing rapidly to form the multicellular organism. Note: In this simulation early and late prophase are combined into one stage: prophase. 1. Go to the Virtual Microscope (Links to an external...
