What is the equation for the formation of melanin
Tyrosine➡️Dopaquinone➡️Melanin
Which enzyme controls melanin production in melanocytes?
Melanin production in human melanocytes is controlled by the rate limiting enzyme for melanin synthesis, TYROSINASE
What’s the difference between pheomelanin and eumelanin
Pheomelanin is the red/yellow type of melanin WHILE eumelanin is the brown/black type
What are the end results of meosis and mitosis ?
The end result of mitosis are daughter cells that are genetically identical to parent cell and are diploid
Meosis results in daughter cells that vary genetically and are haploid
