Cell Division & Reproduction - Foundations to Biology

Home

Metaphase

Sister chromatids line up in the middle of the cell

S phase

DNA is replicated (synthesized)

Interphase

G1, S, and G2 are sub-phases of this phase

Prophase

The nuclear membrane breaks apart and disappears

Telophase

cleavage furrow and cell plate form

Anaphase

chromatids are pulled apart to opposite sides of the cell

Interphase or G1

cell is carrying out its normal activity and is not actively dividing

Cytokenesis

When the cell physical divides; splitting of the cytoplasm

Telophase

two nuclei are visible and the nuclear membrane starts to reform

Telophase

chromosomes become more relaxed and begin to uncoil

Cells are smaller and divide more often rather than grow larger because

1: DNA Overload 2: Cells need more 3: More efficient moving wastes and nutrients out

What is the correct sequence of the phase of Mitosis?

PMAT - Prophase, Metaphase, Anaphase, Telophase

n

The number of chromosomes in a body cell is represented by the symbol

Mitosis; Meiosis

Somatic cells are produced by ________________ and gametes are produced by _____________.

Centromere

The structure that holds the sister chromatids together and helps to connect to spindle fibers

Sister chromatids

The two arms of a chromosome that are identical to one another are called?

16 chromosomes

During normal mitosis cell division, a parent cell having 16 chromosomes will produce two daughter cells, each containing

23 (they are haploid "half" the number of chromosomes)

How many chromosomes are found in a typical human sperm or egg cell?

Division rate

Cancer is a disorder in which some cells have lost the ability to control their...

Binary Fission

Prokaryotic cells create identical offspring during the cell division process known as?

Homologous chromosomes

Chromosomes that are similar in size and shape but carry different "options" for a gene or trait are called?

cell movement"; splitting one cell into two cells

Cytokinesis means?

90%

Cells spend approximately how much time in Interphase preparing for division?

Mitosis & Cytokinesis

In the cell cycle, Cell Division includes which phases?

Meiosis

Meiosis or Mitosis? Chromosomes number is halved

Mitosis

Meiosis or Mitosis? Results in two identical daughter cells

Mitosis

Meiosis or Mitosis? occurs in somatic cells only

Meiosis

Meiosis or Mitosis? occurs in germ cells to produce gametes

Meiosis

Meiosis or Mitosis? crossing over occurs

Mitosis

Meiosis or Mitosis? one round of cell division

Meiosis

Meiosis or Mitosis? two rounds of cell division

Meiosis

Meiosis or Mitosis? Results in 4 genetically different cells
