Mitosis/meiosis/pummet squares

Question 1

Mitosis

Answer 1

A type of cell division that occurs in body (somatic)

splits into 2 identical daughter cells, helps in growth and repair,

Question 2

PMAT

Answer 2

The process in which the cells divide

Question 3

Prophase

Answer 3

Stage 2: Chromosomes condense, nuclear membrane disappears

P = pre

Question 4

Metaphase

Answer 4

Stage 3: the 46 chromosomes line up in single file. Spindle fibers attach to centromeres

M = middle

Question 5

Anaphase

Answer 5

Stage 4: the sister chromatids separate

A = away

Question 6

Telophase

Answer 6

Stage 5: nuclear membrane reforms. Each new cell is diploid (has 46 chromosomes)

T = The end

Question 7

Interphase

Answer 7

stage 1: Chromosomes replicate to have two chromatids. (the DNA doubles)

Question 8

Cytokinesis

Answer 8

Stage 6: Cell membranes form, making two daughter cells, each with a nucleus

Question 9

Gametes

Answer 9

Egg and sperm cell

Question 10

Meiosis

Answer 10

Meiosis only occurs in sex cells to produce gametes. Its results in four DIFFERENT daughter cells that are haploid (23 chromosomes)

Miosis undertake PMAT twice (meiosis 1 and meiosis 2)

Question 11

Homologous

Answer 11

same size and banding pattern

Question 12

Meiosis 1

Answer 12

Interphase 1: normal

Prophase 1: normal

Metaphase 1: Chromosomes line up in HOMOLOGOUS PAIRS

Anaphase 1: Homologous pairs are separated

Telophase 1: (the end) Two cells with 23 chromosomes each (haploid)

Question 13

Metaphase 1 (more depth)

Answer 13

Replicated chromosomes form homologous pairs attached to spindle fibres and lined up in the middle

Question 14

Meiosis 2

Answer 14

Each of the two haploid daughter cells undergo division again (only MAT)

Metaphase 2: Chromosomes line up on the equator attached to spindle fib

Question 15

Locus

Answer 15

Location of a gene on a chromosome

Question 16

Allele

Answer 16

Different versions of a gene

Question 17

Genotypes

Answer 17

What alleles you have
