Transcription/Translation
foldable
Fold your paper so the two ends meet
in the middle. Label Transcription on
one side and Translation on the other.
Transcription
• WHAT? DNA is transcribed into mRNA. That means I am copying
DNA and making mRNA.
• Location? Nucleus
• Why? DNA cannot leave the nucleus, so the messenger RNA has to
take the nucleotide sequence to the ribosome to make proteins.
Cut out the picture below. Label and color the DNA blue and the mRNA red.
Translation
What?
– mRNA nucleotide code is translated into an amino
acid sequence to make a protein.
How?
- tRNA brings an amino acid with an anticodon to the
rRNA
- tRNA binds to a codon in mRNA and releases a amino
acid
- a chain of amino acids is formed = PROTEIN!
• Location? ribosome (rRNA)
• Why? Need proteins to carry out life functions
Translation con’t
Cut out the picture
below. Label
and color:
mRNA –red (B)
tRNA-green
Amino acidsyellow
Ribosome-pink
Circle 3 bases on mRNA and label as codon.
Circle complementary 3 bases on tRNA and label as anticodon.
Label the amino acid sequence.
Cut out the steps of protein synthesis, and
glue them in order on the back of your
foldable.
