Mitochondrial genes are carried by a molecule of circular DNA of 16569b, inhereted by the mother Mitochondrial DNA, because the mitochondria of sperm are destroyed by the egg cell after fertilization. After the penetration of the sperm , the egg cell keeps the nuclear contain,and all the rest will be destroyed by enzyms, so by this mechanism, the mitochondria still just the mother’s one, plus to this, the mitochondria of the sperm is presented in its tail for proplling the cell. This mitochondrial DNA is transmissed to all of the mother’s descendants boys and girls, but this transmission stops at each boy, so if there is any mutation to this DNA, all the girls inherit it to their descendants. The mitochondrial DNA contain a lot of genes such as :NADH dehydrogenase, ATP synthase. The most known desease by mitochondrial DNA is leber’s Hereditary optic Atrophy wich is a brutal loss of vision and quickly for teenagers and young adults.
New research links urban planning and political polarization.
- Canadian researchers find that excessive reliance on cars changes political views.
- Decades of car-centric urban planning normalized unsustainable lifestyles.
- People who prefer personal comfort elect politicians who represent such views.
Progressive America would be half as big, but twice as populated as its conservative twin.
- America's two political tribes have consolidated into 'red' and 'blue' nations, with seemingly irreconcilable differences.
- Perhaps the best way to stop the infighting is to go for a divorce and give the two nations a country each
- Based on the UN's partition plan for Israel/Palestine, this proposal provides territorial contiguity and sea access to both 'red' and 'blue' America
Science and the squishiness of the human mind. The joys of wearing whatever the hell you want, and so much more.
- Why can't we have a human-sized cat tree?
- What would happen if you got a spoonful of a neutron star?
- Why do we insist on dividing our wonderfully complex selves into boring little boxes
