Purpose of transcription – synthesize mRNA

Purpose of translation – synthesize protein

Base pairing between DNA and RNA

    • DNA adenine pairs with RNA uracil

    • DNA thymine pairs with RNA adenine

    • DNA cytosine pairs with RNA guanine

    • DNA guanine pairs with RNA cytosine

Types of RNA

    • Messenger RNA (mRNA

    • Ribosomal RNA (Ribosome or rRNA)

    • Transfer RNA (tRNA


Activity
