2. Scientific Concept Many eukaryotes have two copies of each type of chromosome in their nuclei, so their chromosome complement is said to be diploid. Chromosomes are the genetic units divided by mitosis.Each chromosome is duplicated into two exact copies called sister chromatids during S stages in interphase. Mitosis separates the sister chromatids and places one in each of the two daughter nuclei produced by the division. The equal distribution of daughter chromosomes to each of the two cells that result from cell division is chromosome segregation.

3. Mitotic cell cycle basically comprised of 4 phases:

5. To identify biology student teachers’ misconceptions of cell divisions using drawings and interviews which they possess about the cell division processes and both the content and scope of these misconceptions.

7. Research Background A total of 124 student teachers, who were studying to become secondary biology teachers at the Faculty of Education in Selcuk University in Turkey. Participants previously had studied cell division in cytology, genetics, and molecular biology, as a school subject during various semesters.

9. The first method is method of drawing. The participants were informed about the drawing method before this application and some practices were applied about this method.

11. Cont. The second method to examine the university student’s knowledge is individual interviews. After the drawings were evaluated, individual interviews were conducted about the detailed subjects with 15 randomly chosen who demonstrated misconceptions. The purpose was to check the validity of the interpretation of the drawings. In the interview, these students were asked to respond to questions like: What are chromosomes and sister chromatids? How do the chromosomes act during mitosis?
