mitosis & meiosis

Question 1

also known as cell reproduction

Answer 1

cell division

Question 2

is tightly coiled in an organized structure

Answer 2

chromosome

Question 3

a complex of macromolecules composed of DNA and proteins, formed inside a nucleus

Answer 3

chromatin

Question 4

refers to each strand of duplicated chromosomes

Answer 4

chromatid

Question 5

series of events that takes place in a cell as it grows and divides

Answer 5

cell cycle

Question 6

is the growth period in the cell cycle

Answer 6

interphase

Question 7

first part of the cell cycle wherein the cell carries out its normal metabolic functions

Answer 7

G1 phase or Gap 1 phase

Question 8

second part of the cell cycle, which refers to the time that the cell makes a complete copy of the DNA in its nucleus

Answer 8

S phase or Synthesis phase

Question 9

cell grows more, make proteins and organelles and begins to recognize its content to preparation for mitosis

Answer 9

G2 phase or Gap 2 phase

Question 10

cell divides its copied DNA and cytoplasm to make two new cell. nuclear DNA of the cell condenses and is pulled apart

Answer 10

M phase or Mitotic phase

Question 11

occurs in non-reproductive cells, or somatic cells, except the sex cells.

Answer 11

mitosis

Question 11

is the division of nucleus into two genetically identical nuclei containing the same full set of DNA.

Answer 11

mitosis

Question 11

chromatin condenses into chromosomes. nucleolus disappears. centrosomes are starting to migrate to opposite sides of the cell. formation of the spindle fiber.

Answer 11

prophase

Question 12

nuclear membrane is now gone. chromosomes are starting to line up in the middle of the cell. the spindle fibers are now connected to kinetochore.

Answer 12

metaphase

Question 13

sister chromatids are separated from each other. chromosomes move toward the poles of the cell.

Answer 13

anaphase

Question 14

two complete sets of identical chromosomes are now positioned at each of the pole of the cell. microtubules and spindle fibers are disintegrated. nuclear membrane starts to form while the chromosomes begin to uncoil or become less dense.

Answer 14

telophase

Question 15

division of the cytoplasm. cell division will not be completed until the entire cytoplasm divides.

Answer 15

cytokinesis

Question 16

cell contains a single set of chromosomes

Answer 16

haploid cells

Question 17

cell contains two copies of each chromosomes

Answer 17

diploid cells

Question 18

are chromosome pairs containing a maternal and paternal chromatids that are similar in length

Answer 18

homologous chromosomes

Question 19

focuses on the division of homologous chromosomes to produce two haploid cells with duplicated chromosome

Answer 19

meiosis 1

Question 20

crossing over occurs

Answer 20

synapsis

Question 21

the breaking down of nuclear envelope. spindle fibers begin to assemble. duplicated chromosomes condense, while the homologous pair line up by gene precisely in its entire length.

Answer 21

prophase 1

Question 22

the spindle apparatus forms from opposite ends
of the cell. The spindle apparatus then sends out spindle fibers to attach to the
chromosomes.

Answer 22

metaphase 1

Question 23

The homologous chromosomes are pulled apart and move towards opposite ends of the cell by the action of spindle fibers. sister chromatids remain together and do not separate at their centromeres throughout meiosis 1.

Answer 23

anaphase 1

Question 24

The chromosomes are now at opposite ends of the cell and begin to form two distinct chromosome clusters. nuclear division begins, and the parent cell is divided in half, forming 2 daughter cells.

Answer 24

telophase 1

Question 25

divides sister chromatids, resulting in sex cells with only half of the chromosome number.

Answer 25

meiosis 2

Question 26

divides sister chromatids, resulting in sex cells with only half of the chromosome number.

Answer 26

meiosis 2

Question 27

the chromosomes begin to re-condense and spindle fibers begin to form once again.

Answer 27

prophase 2

Question 28

chromosome lines up along the equator through the spindle fiber.

Answer 28

metaphase 2

Question 29

the centromere splits, freeing the sister chromatids from each other. At this point, spindle fibers begin to shorten, pulling the newly-separated sister chromatids towards opposite ends of the cell.

Answer 29

anaphase 2

Question 30

nuclear envelope forms around each set of chromosomes at opposite ends of the cell. cell division begins again in each of the two daughter cells, creating 4 daughter cells.

Answer 30

telophase 2

Question 31

one cell division. homologous chromosomes never pair up. results in two diploid cells

Answer 31

mitosis

Question 32

two cell division. homologous chromosomes pair up along the equator. result in 4 haploid cells

Answer 32

meiosis
