• RNA & Protein synthesis
RNA & Protein SynthesisWhy RNA is Just as Cool as DNA (4:43):
Synthesis: We’ll compare & contrast RNA with DNA & teell you
why DNA should be sharing the limelight!

• Promoter site identified.
• RNA polymerase binds to
promoter site.
• Separates strands of DNA
(breaking H+ bonds)

Protein SynthesisAmino Acids are __________,
th___________ or __________.
Polypeptide/Protein?
• Long chains of amino acids (20
different).
• Order of amino acids determines
the properties & shape of
protein.
• Shape of protein determines its
function.
Amino Acids are __________, the building blocks of
___________ or __________.
p. 366-367
monomerspolypeptides proteins
Protein SynthesisReading the genetic code.
• Read three letters at a time.
• Each “word” (codon) is three bases long.
• A codon represents a single amino acid.
p. 367
Protein SynthesisReading the genetic code.
mRNA contains that code.
Any message must have a
beginning & end.
• Start Codon (only 1)
- AUG = Methionine
• Stop Codons (3)
- UAA, UAG, & UGA
p. 367
Protein SynthesisTranscription & Translation Worksheet;
• Fill in the appropriate transcription of DNA & translation of
mRNA, tRNA, or amino acids.
• Remember that mRNA contains the code & it is the codons
that are used against the amino acid chart.
• Answer the question of the back of the worksheet.
p. 368-370
Guest TeacherThe Ghost In our Genes (49:07):
Synopsis: Following the mapping of the human genome scientists
discovered there is a huge new chapter in the genetics story. Dubbed
epigenetics, it involves the chemical markers on DNA that effectively
turn genes on or off dramatically influencing growth & development.
The markers vary widely from person to person & tissue to tissue &
are influenced not just by the environment but by experiences. Most
remarkably the markers can be inherited generation after generation.
