UNIT 7: PROTEIN SYNTHESIS
UNIT 7: PROTEIN SYNTHESIS
IN THIS UNIT WE WILL EXAMINE HOW PROTEINS CAN BE MADE. WE WILL STUDY HOW DNA'S INSTRUCTIONS FOR BUILDING PROTEINS LEAVES THE NUCLEUS AND TRAVELS INTO THE CYTOPLASM TO THE RIBOSOME, WHERE THE INSTRUCTIONS ARE TRANSLATED INTO PROTEINS. THIS SHOULD BE THE LAST SECTION OF REALLY DETAILED PROCESSES THAT WILL BE EXAMINED.

• Explain the process of protein synthesis:
• Explain the process of protein synthesis:
Transcription that produces an RNA copy of DNA, which is further modified into the three types of RNA

Translation – tRNA supplies appropriate amino acids
Translation – tRNA supplies appropriate amino acids
Amino acids are linked by peptide bonds to form polypeptides. Polypeptide chains form protein molecules. Proteins can be structural (forming a part of the cell materials) or functional (hormones, enzymes, or chemicals involved in cell chemistry).

• Interpret a codon chart to determine the amino acid sequence produced by a particular sequence of bases.
• Interpret a codon chart to determine the amino acid sequence produced by a particular sequence of bases.
• Explain how an amino acid sequence forms a protein that leads to a particular function and phenotype (trait) in an organism
• Explain how an amino acid sequence forms a protein that leads to a particular function and phenotype (trait) in an organism
Bio.3.1.3 Explain how mutations in DNA that result from interactions with the environment (i.e. radiation and chemicals) or new combinations in existing genes lead to changes in function and phenotype.

• Understand that mutations are changes in DNA coding and can be deletions, additions, or substitutions. Mutations can be random and spontaneous or caused by radiation and/or chemical exposure.
• Understand that mutations are changes in DNA coding and can be deletions, additions, or substitutions. Mutations can be random and spontaneous or caused by radiation and/or chemical exposure.
• Develop a cause and effect model in order to describe how mutations: changing amino acid sequence, protein function, phenotype. Only mutations in sex cells (egg and sperm) or in the gamete produced from the primary sex cells can result in heritable changes.
