DNA replication occurs in prophase during the process of cell divisions.

Interphase is the resting phase of mitosis. A chromosome has always two chromatids

during cell division. Diploid (2n) cells are formed as a result of

meiosis. Centrioles are found in the nucleus of a cell.

MISCONCEPTIONS

Scientific explanation

Page 5: 38018043 Misconceptions of Cell Division Held by Student Teachers

1) DNA replication occurs in prophase during the process of cell divisions.

Page 6: 38018043 Misconceptions of Cell Division Held by Student Teachers

- scientific explanation-

DNA replication occurs in S phase ( DNA Synthesis) before

enter mitosis.

Page 7: 38018043 Misconceptions of Cell Division Held by Student Teachers

2) Interphase is the resting phase of mitosis.

Page 8: 38018043 Misconceptions of Cell Division Held by Student Teachers

Interphase is the resting phase before a

dividing cell enter mitosis.

-scientific explanation-

3) A chromosome has always two chromatids during cell division

Page 10: 38018043 Misconceptions of Cell Division Held by Student Teachers

-scientific explanation-

During anaphase 1, homologous

chromosome separate, sister chromatids remain

together.

4) Diploid (2n) cells are formed as a result of meiosis.

Page 12: 38018043 Misconceptions of Cell Division Held by Student Teachers

-scientific explanation-

Meiosis is the process of nuclear division in a living cell by which the chromosomes number is reduced to half from a diploid number (2n) to a

haploid number (n)At the end of meiosis four haploid

(n) nuclei are formed.

5) Centrioles are found in the nucleus of a cell.

Page 14: 38018043 Misconceptions of Cell Division Held by Student Teachers

-scientific explanation-

Centrioles are found near the nucleus so that it can form mitotic spindle during the prophase of the cell cycle.

Drawing

Technique used

Page 16: 38018043 Misconceptions of Cell Division Held by Student Teachers

Level 1: No Drawing: Students replied, “I don’t know,” or no response was given to the statement. Level 2: Non-Representational Drawings: These drawings included identifiable elements of cell division. Also the responses, which included diagrams or formulations instead of the drawings, were evaluated in this category . Level 3: Drawings with Misconceptions: These types of drawings showed some degree of understanding on cell division concepts, but also demonstrated some misconceptions. Level 4: Partial Drawings: The drawings in this category demonstrated partial understanding of the concepts. They included elements of the cell division like prophase, metaphase, anaphase, telophase, etc. Level 5: Comprehensive Representation Drawings: Drawings in this category were the most competent and realistic diagrams of cell division . These drawings showed a sound understanding and contained seven or more elements of the validated response for this particular statement.
