  1. Knowledge Survey Quiz • 5 questions

  2. 1. DNA is typically found as a double helix made of two chains of: • amino acids • monosaccharides • nucleotides • lipids • proteins

  3. 2. A codon is a nucleotide sequence that generally provides instructions for a specific ___ . • amino acid • cell structure • protein • gene • location in a cell

  4. 3. Which of these is the structure where most of the ATP is made in a eukaryotic cell? • Golgi apparatus • mitochondrion • endoplasmic reticulum • nucleus • ribosome

  5. 4. In humans a single gene with two alleles determines whether you have free or attached earlobes; the allele for free earlobes is dominant. A man and a woman, both with free earlobes, produce a child with attached earlobes. What are the odds that the second child they produce will have free earlobes? • 0% • 100% • 50% • 25% • 75%

  6. 5. Which of the following is NOT part of Darwin's mechanism of evolution by natural selection? • overproduction of offspring • differential reproductive success • competition among organisms • acquiring traits because they are needed • genetic variation among individuals

  7. Wait for instructions!!!
