    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.

    Introduction

    • The substances in the first column are proteins:
      • Actin
      • Myosin
      • Melanin
    • The substances in the second column are sugars:
      • Lactose
      • Lactase
    • The substances in the third column are hormones:
      • Testosterone
      • Calcitonin
      • Serotonin
    • The substances listed in the fourth column are lipids:
      • Lipopolysaccharide
      • Glycoprotein
      • Glycolipid

    Transcription vs Translation

    • The document also includes a title slide indicating there may be additional slides for transcription vs translation.
