Recall – Importance of ProteinsSlide3
Incorrect copying of DNA during protein synthesis results in disorders such as…Sickle Cell Anaemia
The need for correct synthesis of proteinsSlide4
AIM
Aim
: To model the process of protein synthesis, producing correct ‘proteins’.Slide5Slide6Slide7
Groups
3 Students
per group
mRNA
(messenger RNA), transfers the coded information from DNA in nucleus to cytoplasm, called Transcription. mRNA student gets DNA card and transcribes it into mRNA.Decoding of mRNA occurs in the Ribosome. The Ribosome will
translate
the mRNA into a
tRNA
( transfer RNA) sequence.
The
tRNA
student will search out the correct anticodon car and flip the card revealing the word. Writing down the word, and completing the sentenceSlide8

STUDENT
Role:
DNA-mRNA Student: Stays at desk (Nucleus) and transcribes
DNA to mRNA:Base paring rules:G – CA – UT – ASlide9

Ribosome
student
Role:
The ribosome students
receives the mRNA at another desk (in the cytoplasm) and transcribes it into tRNA.Base paring rules: U- A A – U

RibosomeSlide12
tRNA
student
Role:
tRNA student will search the side benches for the correct Anticodon (E.g. AUG). Flip the card and write down the word, repeating this until the sentence is complete.The student returns to her group and checks the
sentence
with her group members, then brings it to the
teacher
for
verification
