Cell: Mitosis and the Cell Cycle

Question 1

Mitosis Phases and thier function

Answer 1

Prophase: the chromosomes condense and become visible under a microscope. Because they were copied, each chromosome consists of two identical strands called CHROMATIDS.

Metaphase: chromosomes line up in the middle of the cell. The membrane around the nucleus dissolves.

Anaphase: the chromatids SEPARATE and the two daughter chromosomes are pulled to opposite sides of the cell.

Telophase: the daughter chromosomes stretch out and become thin. A new nuclear membrane forms around each group of chromosomes.

Question 2

Cell Cycle phases and function

Answer 2

Interphase: The longest stage. Cells GROW and perform normal functions. The chromosomes COPY themselves to prepare for cell division.

Mitosis: Division of the NUCLEUS. made up of 4 PHASES (PMAT).

Cytokinesis: Division of the CYTOPLASM and ORGANELLES. The cell membrane pinches in to form two separate cells.

Question 3

Chromatin

Answer 3

long, thread-like strands
of genetic material

Answer 4

tightly wound chromatin

Question 5

Genes

Answer 5

sections of the chromatin that
control specific characteristics of an individual (eye colour, height, etc.)

Question 6

Chromatid

Answer 6

Two identical strands that make up chromosones
