Worked Solution & Example Answer:In the space below draw a diagram of a nucleus during metaphase of mitosis where 2n = 6 - Leaving Cert Biology - Question 5 - 2005
Step 1
Draw a diagram of a nucleus during metaphase of mitosis where 2n = 6.
Answer
- Begin the diagram representing the nucleus, which should be roughly circular.
- Illustrate six chromosomes arranged at the metaphase plate, ensuring they are distinct and lined up properly.
- Draw the spindle fibers extending from the centrosomes at each pole of the cell, with clear lines depicting their connection to the centromeres of the chromosomes.
- Label the spindle fibers and the centromeres on the diagram for clarity.
Step 2
State a function of mitosis in a single-celled organism.
Answer
The primary function of mitosis in a single-celled organism is reproduction. Through the process of binary fission, the organism can duplicate its genetic material and divide into two identical daughter cells, allowing for growth and population increase.
Step 3
Step 4
State one way in which mitosis differs from meiosis.
Answer
One key difference between mitosis and meiosis is that mitosis results in two genetically identical daughter cells, whereas meiosis produces four genetically diverse daughter cells with half the chromosome number of the original cell.
