1. Protein Synthesis
Mrs. Harlin

2. Summarize the relationship among DNA, proteins and amino acids in carrying out the work of cells and how this is similar in all organisms.
4.1.2

3. The sequence in nucleotides in DNA codes for specific amino acids which link to form proteins.
Recall

4. All 5 nitrogenous bases (A, T, C, G, U) found in nucleic acids (DNA and RNA) is the same for all organisms.
Identify

5. Summarize Protein Synthesis DNA is transcribed to mRNA in the nucleus
mRNA migrates to a ribosome in the cytoplasm
tRNA transfers an amino acid to the ribosome during translation
Anticodon on tRNA matches up with codon on mRNA and drops of amino acid
Amino acids are linked together with peptide bonds to form a protein.
Summarize

6. Amino Acids
20 types
The combination of the types makes 1000s of proteins
Similarity in proteins is what determines relationships between organisms.
Side chains are what make each amino acid different and determine how they bond and fold in proteins.
