Biology

Aleks [24]3 years ago

The cell cycle is composed of S (synthetic) phase and M (Mitotic) phase. In between are G1 and G2 phases. cyclin-dependent kinases propel cell division. Their activation results in the progression of a cell from one phase to another while their inactivation arrests a cell in a phase. In case of damage to DNA during a cell cycle, transcription factors p53 (a renowned tumor suppressor) are recruited. P53 inhibits cyclins-dependent kinases and also induces cell apoptosis if DNA is not repaired.

Schach [20]

Answer:

LHON (Leber Hereditary Optic Neuropathy): Is a disease that is characterized by loss of vision in young adults.

Sickle cell anemia: Is a disease characterized by production of abnormally shaped red blood cells, that is, not round in shape as normal but are 'sickle' shaped or elongated/crescent shaped.  

Both diseases are heritable But LHON is caused by mutations existing in the mitochondrion thus only inherited maternally.

Sickle cell anemia is caused by mutations in the HBB gene which produces the beta subunit of hemoglobin. It is inherited from recessive genes of both parents.
