Chapter 6 Chap 5   DNA and the expression of genes   Chap 7 Flashcards  Self Quiz Notes Ppt
  1. DNA is a double helix   macromolecule made of nucleotides  .
     
  2. Sequences of nucleotides called genes   control cellular functions and make up an individual's genome.


     
  3. Much of the human genome   are non-coding DNA that are not genes   .
     
  4. Gene expression   (exhibiting a phenotype) involves 2 steps:
     
    • Transcription involves copying genetic information on DNA   to a RNA   transcript.
       
    • Translation involves the production of proteins   from nucleotide sequences copied onto the RNA   transcript.



     
  5. A mutation   is a change in the DNA sequence that may affect proteins.
