Bio Cell Division Test

Question 1

Mitosis

Answer 1

The division of a cell into two identical cells. Involves prophase, metaphase, anaphase, and telophase.

Question 2

Meiosis

Answer 2

the reduction of a 46 chromosome parent cell into 4 daughter cells with 23 chromosome each. used to produce gametes when reproducing. Also important is the recombination done during this, which further modifies the genetic makeup of the DNA sequence

Question 3

Chromosome

Answer 3

A condensed form of the human genome, present inside all cells. Is replicated and split during mitosis.

Question 4

Metaphase

Answer 4

Chromosomes line up at the centre of the cell, and are attached to spindle fibres.

Question 5

Prophase

Answer 5

Set up for division. Spindle fibres form, nucleus dissolves, and chromasomes condense.

Question 6

Anaphase

Answer 6

Sister chromatids are broken off, and are pulled to different sides of the cell

Question 7

telophase

Answer 7

Nuclei begin to form around each new DNA bundle, and a cleavage furrow begins to form

Question 8

Cytokinesis

Answer 8

the cleavage furrow restricts until it shears, leaving two new identical cells

Question 9

Nondisjunction

Answer 9

An abornomal chromosome seperation leaves the resultant cells with too many or too few chromosomes. Extra chromosomes are called trisomy, while a lack are called monosomy

Question 10

Common non-disjunction disorders

Answer 10

Downs Syndrome, Turners syndrome, Klinefelters syndrome, and Edwards syndrom

Question 11

Spermatogenesis

Answer 11

Process of sperm formation, sperm prcecursors are formed by normal meisois from a diploid cell

Question 12

Oogensis

Answer 12

Cells halt production at prophase 1, during a period one is produced, but splits into a main larger egg cell and smaller bodies that die off
