Bio Mitosis And Meiosis Quiz

Front 1

How does genetic information get passed down from generation to generation

Back 1

Mitosis meiosis through dna reproductive cells conjugation bridges and adaptations

Front 2

What is the value of variety

Back 2

Harder to spread diseases everyone is unique in their own way and a genetic disorder doesn't have to affect everyone

Front 3

dna is what

Back 3

Deoxy ribonucleic acid can be seen in different forms

Front 4

Chromatin

Back 4

String like form of dna

Front 5

Chromatid

Back 5

Half of a chromosome and contains all dna necessary for that chromosome

Front 6

Chromosome

Back 6

X shape nr2 identical chromatid joined together by a centromere

Front 7

Gene

Back 7

A specific part or sequence of dna that codes for a particular trait example hair colour eye colour blood type e.t.c

Front 8

loci

Back 8

Location of a gene

Front 9

Asexual reproduction

Back 9

Copies and clowns and producing offspring genetically identical to parent and mostunicellular organisms reproduce asexually

Front 10

Budding

Back 10

new organism from a growth on the body of an organism

Front 11

Fragmentation

Back 11

Are part of an organism brakes off and continues growing independently

Front 12

Mitosis

Back 12

Eukaryotic cells divide equally into two new nuclear

Front 13

Cytokinesis

Back 13

The rest of the cell divides its natural organs amongst the two new cells

Front 14

Interphase

Back 14

When a cell grows repairs itself and prepares to divide and once the cell cell gets a signal to divide the dna make a copy of itself inside the nucleus

Front 15

Prophase

Back 15

Chromatin shortens and thickens into chromosomes. Centrioles migrate to opposite poles and spindle fibres attached to the centromere chromosomes . And the nuclear membrane dissolves

Front 16

Metaphase

Back 16

Spindle fibres move and align chromosomes a long the equator of the cell

Front 17

Anaphase

Back 17

Centromere divide and sister chromatids move to opposite poles of the cell

Front 18

Telophase

Back 18

Chromatic kids have reached the opposite poles. Chromatids unravel into chromatin and spindle fibres dissolve

Front 19

Cloning

Back 19

The process affirming identical offspring from a single cell or tissue

Front 20

Biotechnology

Back 20

Use and modification of organisms for applications in engineering industry and medicine

Front 21

Gametes

Back 21

a sex cell inhumans is a sperm and egg half the genetic material than a somatic cell

Front 22

Somatic

Back 22

Any other cell in your body except sex cells

Front 23

Zygote

Back 23

Fertilised gamete when a sperm meets egg

Front 24

Haploid

Back 24

Half the genetic material 23 chromosomes in humans

Front 25

Diploid

Back 25

Full set of dna 46 chromosomes

Front 26

Meiosis

Back 26

The process of producing gametes 2 cycles to complete meiosis1 and meiosis 2

Front 27

homologous chromosomes

Back 27

Same location matching pairs of chromosomes similar in size and carrying the same genes

Front 28

meiosis1

Back 28

End result will be two cells with half the number of chromosomes and a separation of homologous chromosomes

Front 29

Prophase 1

Back 29

Chromatin shortens and thickens forming chromosomes. homologous chromosomes form a tetrad, nuclear membrane dissolves, and spindle fibres start to form

Front 30

Metaphase 1

Back 30

Spindle fibres attach to chromosomes temple tetrad to the equator as pairs

Front 31

Anaphase 1

Back 31

homologous chromosomes separate to different poles by spindle fibres. They are not, ted's there still chromosomes

Front 32

Telophase between meiosis 1 and meiosis 2

Back 32

Spindle fibres disintegrate a nuclear membrane reforms. Chromosomes and rolanda, 10 and cytokinesis occurs in a cell pinches and cytoplasmic organelles are divided

Front 33

Prophase 2

Back 33

Chromatin shortens and lengthens nuclear membrane dissolves and Centrioles migrate to poles and spindle fibres begin to form

Front 34

metaphase 2

Back 34

Chromosomes are pulled to equator by spindle fibres attached to centromere

Front 35

Anaphase 2

Back 35

Centromeres split pulling sister chromatids to opposite poles

Front 36

Telophase 2

Back 36

Nuclear membrane reforms around each step of chromatin spindle fibres disintegrate and chromatid unravel into chromatin

Front 37

Tresomy

Back 37

a chromosomeal abnormality with 3 homologous chromosomes instead of the typical pair

Front 38

Monomy

Back 38

a chromosomal abnormality with a single chromosome instead of a typical pair

Front 39

non disjunction

Back 39

The failure of homologous chromosomes to separate and proceed to up support during cell division and the result is that one cell has too many chromosomes in one cell has to few n both results pose problems for the offspring

Front 40

Atypical meiosis

Back 40

A cell division does not always a car properly sometimes the chromosomes do not divide evenly into the forming cells nso marcel the damage is minimal but the cell is replaced by other property sales in a sec southend the damage is profound because each cell in the new organism will have the incorrect number of chromosomes

Front 41

Karyotype

Back 41

Chromosomes of an individual that have been sorted and arranged according to size and type

Front 42

autosome

Back 42

Non sex chromosomes

Front 43

Gametogenesis

Back 43

The formation of sex cells

Front 44

Difference between sperm and ovum

Back 44

sperm, male gametes produced in the testis have negligible amount of cytoplasm and nucleus is compact built for speed. Ovum, female gamete produced in the ovary have bulky cytoplasm and a centrally located nucleus produced singly
