Learner Objectives

You should be able to:

  1. Draw a diagram, create a concept map, or write a paragraph that explains the relationships among these terms:

    2. chromosome allele gene expression
    trait DNA RNA polymerase
    messenger RNA transfer RNA ribosomal RNA
    codons anticodons ribosomes
    transcription translation RNA processing
    amino acids polypeptides protein
    protein folding primary structure quaternary structure

  2. Explain how the sequence of DNA nucleotides for a specific allele, such as the allele for sickle cell disease or the allele for cystic fibrosis, is related to the production of a specific protein.

  3. Explain transcription and translation, and the roles of RNA polymerase, messenger RNA, transfer RNA, ribosomal RNA, and ribosomes in carrying out these two processes.

  4. Explain, in general terms, how the order and kinds of amino acids that make up a protein determine its final conformation and, ultimately, its function.

  5. Define the term mutation.

  6. Describe the types of mutations that can occur in a gene and the effect, if any, they have on the protein that is produced when the gene is expressed.
