Study Notes

Transcription e Translation

  • Transcription e translation es duo processo fundamental in le biologia cellular, responsable pro le production de proteina.
  • Transcription es le processo per le qual le information genetic in DNA es copiate in RNA.
  • Translation es le processo per le qual le information genetic in RNA es usate pro construir proteina.
  • Le processo de transcription e translation es essential pro le functionamento de tote le cellula vivente.

Exemplos de Moleculas:

  • Actin es un proteina que es un componente major del cytoschelete in cellulas eucaryotic.
  • Lactose es un saccharide que es trovate in le lacte.
  • Testosterone es un hormone sexual masculine.
  • Lipopolysaccharide es un componente del membrana externe de bacteria gram-negative.
  • Myosin es un proteina que es responsabile pro le contraction muscular.
  • Lactase es un enzyma que es responsabile pro le digestion de lactose.
  • Keratin es un proteina que es trovate in le cuticula del capillos, ungulas e pelle.
  • Glycoprotein es un proteina que es ligat a un carbohydrato.
  • Melanin es un pigmento que da color al pelle, capillos e oculos.
  • Calcitonin es un hormone que regula le nivellos de calcio in le sanguine.
  • Serotonin es un neurotransmitter que es responsabile pro le humor, appetite e somno.
  • Glycolipid es un lipido que es ligat a un carbohydrato.
