Although techniques are available for determining the sequences of amino acids in proteins, it is becoming more and more common to sequence proteins indirectly by determining the base sequence of the gene for the protein and then inferring the amino acid sequence from the genetic-code relation-ships. Suggest why the latter technique is being used for proteins.
Answer to relevant QuestionsSometimes knowing the DNA sequence of a gene that codes for a protein does not tell you the amino acid sequence. Suggest several reasons why this is so. What are the key differences between DNA microarrays and protein microarrays, and how they are used in research? Both ADA-SCID and type I diabetes are diseases based on lack of a particular protein. Why has the pioneering work on gene therapy focused on SCID instead of on diabetes? What determines the family in which a virus is categorized? Describe the nature of p53 reactivation as a cancer-fighting strategy.
