Transcript Translation

Translation
Translation:
From mRNA to Protein
• Translation is the process of changing the
information from an order of nitrogen bases
in mRNA into the order of amino acids.
• This takes place at the ribosomes in the
cytoplasm
Translation
1. When mRNA enters
the cytoplasm,
ribosomes attach
– For proteins to be
made 20 different
amino acids must be
brought to the
ribosomes.
tRNA
2. tRNA brings the amino acids to the mRNA
strand
– tRNA functions as a delivery service.
– It’s only function is to find it’s match and deliver the
amino acid there.
Translation
3. Another tRNA bonds to codon, AA’s bond
together
– This continues until a stop codon is reached.
– Amino acid chains then become proteins
tRNA Structure
• tRNA is made of 2 parts:
– Anticodon (driver)
– Amino acid (delivery)
• Called anticodons because they
bond to the codon in mRNA
