3. You are interested in testing the effect of a drug on human cells. These cells have been sampled and evenly split into two separate cell cultures. You trigger cell division using a growth factor in both cell cultures. This synchronises the start of mitosis so you can easily detect the effect of the drug on the progress through the mitotic phases. Immediately after mitosis begins, you expose one cell culture to the drug (treatment + drug) and compare their progress through the mitotic phases under the microscope to the cells that are not exposed to the drug (control - drug). Here are your observations: Cells from both cell cultures lack their nuclear membranes. Individual chromosomes are clearly visible in both cell cultures Cells from the control culture (- drug) have their chromosomes aligned (see figure below) Cells from the treatment (+ drug) have their chromosomes dispersed in the cell (see figure below). What effect does the drug have on the chromosomes? Indicate two consequences that the drug will have on the progress through the cell cycle. Cells after 8h Treatment (+ drug) Control (-drug)

Oogenesis
The formation of the ovum (mature female gamete) from undifferentiated germ cells is called oogenesis. This process takes place in the ovaries (female gonads). Oogenesis consists of three stages known as the multiplication phase, growth phase, and maturation phase.
Cell Division
Cell division involves the formation of new daughter cells from the parent cells. It is a part of the cell cycle that takes place in both prokaryotic and eukaryotic organisms. Cell division is required for three main reasons:
Question
Transcribed Image Text:3. You are interested in testing the effect of a drug on human cells. These cells have been sampled and
evenly split into two separate cell cultures. You trigger cell division using a growth factor in both cell
cultures. This synchronises the start of mitosis so you can easily detect the effect of the drug on the
progress through the mitotic phases.
Immediately after mitosis begins, you expose one cell culture to the drug (treatment + drug) and
compare their progress through the mitotic phases under the microscope to the cells that are not
exposed to the drug (control - drug).
Here are your observations:

Cells from both cell cultures lack their nuclear membranes.
Individual chromosomes are clearly visible in both cell cultures
Cells from the control culture (- drug) have their chromosomes aligned (see figure below)
Cells from the treatment (+ drug) have their chromosomes dispersed in the cell (see figure
below).
What effect does the drug have on the chromosomes? Indicate two consequences that the drug will
have on the progress through the cell cycle.
