• 1 Given the following DNA sequence, what is the
  amino acid sequence?
• TACACAGTATATACT
• 2 What is the name of the process of going from
  the DNA code to the mRNA code?
• 3 Define codon
• Extra credit name the enzyme that creates mRNA

2

• 1 Given the following DNA sequence, what is the
  amino acid sequence?
• TACACAGTATATACT
• AUG-UGU-CAU-AUA-UGA
• methionine- cysteine-histidine-isoleucine-stop
• 2 What is the name of the process of going from
  the DNA code to the mRNA code?
• Transcription
• 3 Define codon
• Three nucleotides (or bases) on an mRNA molecule
  (that stand for a specific amino acid)
• Extra credit RNA Polymerase

3

• Weve copied the DNA molecule into mRNA, which is
  called
• Transcription
• Now, use mRNA to make a string of amino acids (a
  protein)-
• TRANSLATION

Introducing..

• tRNA
• Transfer RNA
• rRNA
• Ribosomal RNA
• How many RNA molecules are there?
• ? questions, bio theater

7
tRNA

• In cytoplasm
• 1 tRNA carries 1 amino acid
• Codons of mRNA match anti-codons of tRNA

8

• Ribosome made of rRNA acts like match maker
• tRNA anti-codon pairs with mRNA codon
• Start codon is AUG
• Amino acids bond, form protein
• Several stop codons

• TRANSCRITION IN THE NUCLEUS
• DNA ? mRNA
• TRANSLATION IN THE CYTOPLASM
• mRNA ? Ribosomes
• Ribosomes bring together mRNA and tRNA by
  matching base pairs (codons and anti-codons).
• tRNA carries amino acids
• Amino acids join to form proteins
