Cell Cycle, Mitosis, And Meiosis

Front 1

Interphase

Back 1

period between one cell division and the next one

Front 2

Mitosis

Back 2

A nuclear division in which the chromosome number remains the same

Front 3

DNA Polymerase

Back 3

Breaks hydrogen bonds holding one base pair to another

Front 4

Semi Conservative Replication

Back 4

Allows you to conserve one of the two strands of DNA. Proposed in 1951 by Walter and Crick.

Front 5

Centromere

Back 5

Ties or holds together the two strands of DNA

Front 6

Prophase

Back 6

The first stage of mitosis where the condensation or compaction of chromosomes is the main event.

Front 7

Metaphase

Back 7

The second stage of mitosis where the chromosomes are lined up in the center of the spindle.

Front 8

Metaphase Plate

Back 8

Imaginary line in the middle of the mitotic spindle.

Front 9

Anaphase

Back 9

The third phase of mitosis that involves the movement of chromosomes towards each of the two poles. Ends when the chromosomes reach the poles.

Front 10

Telophase

Back 10

The fourth phase of mitosis. The nuclear envelope begins to reform and the mitotic spindle disappears. The cleavage furrow also forms.

Front 11

Cleavage Furrow

Back 11

Pinching in or constriction in the middle of the cell.

Front 12

Diploid Chromosome Number

Back 12

Two copies of each chromosome present. Production of sperm and egg begin with this type of cell

Front 13

Haploid Number of Chromosomes

Back 13

One copy of each chromosome is present.

Front 14

Meiosis

Back 14

The nuclear division that reduces chromosome number by one half.

Front 15

Prophase 1

Back 15

Stage in meiosis where mitotic spindles form and the nuclear envelope disppears

Front 16

Synapsis

Back 16

The pairing up of homologous chromosomes during Prophase 1 of meiosis

Front 17

Metaphase 1

Back 17

Stage in meiosis that aligns pairs of chromosomes but not individual chromosomes

Front 18

Anaphase 1

Back 18

Stage in meiosis where chromosomes move toward the poles

Front 19

Telophase 1

Back 19

Stage in meiosis where the chromosome number is 1/2 of what it started with and the chromosomes begin to reextend

Front 20

Prophase 2

Back 20

Stage in meiosis where the same events of Prophase 1 occur but with half the number of chromosomes

Front 21

Metaphase 2

Back 21

Stage in meiosis 2 where chromosomes align on the metaphase plate

Front 22

Anaphase 2

Back 22

Stage in meiosis 2 that begins with the splitting of centromeres

Front 23

Telophase 2

Back 23

Stage in meiosis 2 that begins when the chromosomes reach the poles.

Front 24

DNA synthesis is a(n)......... process

Back 24

enzyme catalyzed

Front 25

Cytokenisis in plant cells results in the formation of what structure?

Back 25

Cell Wall
