Nucleus:
contains genetic material
1 of 16
Chromosomes:
The human cell nucleus contain 23 pair of chromosome
2 of 16
Gene:
Control the development of different characteristic e.g. hair color and how organism functions
3 of 16
Genotype:
Is all the gene it has
4 of 16
Phenotype:
the characteristic that an organism display
5 of 16
Allele:
genes
6 of 16
Homozygous:
you have two alleles the same for that particular gene
7 of 16
Heterozygous:
You have two different alleles for that particular gene
8 of 16
Sex chromosome
All men have X and Y Chromosome: XY The Y chromosome causes male characteristic All women have two X chromosome: XX
9 of 16
Inherited:
one or both parent carry a faulty allele and pass it on to their child
10 of 16
Cystic fibrosis
Cell membrane caused by a faulty recessive Symptoms: Thick sticky mucus in the air passage, gut and pancreas. Breathing difficulty, chest infection, difficulty in digesting food
11 of 16
Huntington
disease: caused by dominant allele Symptoms Causes tremors(shaking) Clumsiness Memory loss Mood change Pure concentration
12 of 16
Pre-implantation genetic diagnosis
Doctors can test the embryo if they got certain genetic disorder. Doctors only choose health embryo to implant into mother’s womb. Discard other embryos with genetic disease
13 of 16
Embryonic stem cell:
Unspecialized Doctors can turn the stem cell into any kind of cell they want. After removing the stem cell from the embryo
14 of 16
Adult stem cell:
Specialized They can repair their selves if they get damaged Stem cells can be used to treat illnesses e.g. sickle cell anomia can be treated by bone marrow transplant. Replace old faulty genes

Asexually:
without sexual reproduction to form clones Bacteria Animal plant
