Draw and label G1 and G2 stages of interphase and each stage of mitosis (in order) for a cell that has two large and two small chromosomes, 2n=4. For unreplicated chromosome draw a line ( / ) and for replicated chromosome draw an X. Since we are focusing on the DNA, you can skip drawing the nuclear membrane or spindle fibers. For simplicity, do not indicate that the chromosomes are decondensed chromatin during interphase. Mark and label a place on one of the large chromosomes with the dominant allele of the “A” gene and put the recessive allele “a” on the other homolog. Mark and label a place on one of the small chromosomes with allele “B” and put the recessive allele “b” on the other homolog.

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 hon

Explain why you chose the cell you did discussing the changes in chromosome number nd DNA content of a cell throughout the cell cycle. You should also explain if any of the other images could represent a cell from this organism in stages of meiosis or mitosis or other stages of the cell cycle. X Xx C "₁ XX B XX X X

Assume that cell does mitosis Assume that cell does meiosis What is the diploid number of chromosomes in this organism? Give the number of chromosomes and the number of DNA molecules per cell present at the stages represented. I tried to solve them, but I'm not sure what I did right and what was wrong. Please correct it for me. See that attached photo.
Biologists have long been interested in the effects of radiation on cells. In one experiment, researchers examined the effect of radium on mitosis of chick embryo cells growing in culture. A population of experimental cells was examined under the microscope for the number of cells in telophase (as a measure of mitosis occurring) before, during, and after exposure to radium. The results are shown in the Figure. What is the effect of radium exposure on mitosis? Source: R. G. Canti and M. Donaldson. 1926. The effect of radium on mitosis in vitro.

The somatic cells of a particular plant each contain a total of 40 chromosomes. How do the chromosomes of this plant differ from the chromosomes of humans, who also have a total of 40? O This plant is more like animals than like another plant that has 10 total chromosomes. The genes on this plant's largest chromosome are significantly different than those on the largest human chromosome. This plant's sex cells have chromosomes that can synapse with human chromosomes in the laboratory. O This plant's sex cells would have 80 chromosomes when entering meiosis.
