DNA Structure

Structure of DNA: Use information in this video to answer the questions on the rest of this worksheet. What type of biomolecule is DNA? Protein Nucleic Acid Carbohydrate Lipid Fill in the blanks DNA contains the information that determines inherited characteristics. It has the code for making proteins. In eukaryotic cells, DNA is found in the _. Lysosome Ribosome Rough ER Nucleus Fill in the blank - SPELLING COUNTS!! The building block, or monomer, of DNA is a nucleotide. Label the parts of the nucleotide below -- SPELLING COUNTS! Click on the bubbles to fill in these missing labels: phosphate group, nitrogen base, 5 carbon sugar Phosphate Group 5 carbon sugar Nitrogen Base How many unique nitrogen bases are there in DNA? 1 2 3 4 Sort the Bases Sort the nitrogen bases into their specific molecule type: Purine Adenine Guanine Pyrimidine Cytosine Thymine Pyrimidines will always pair with: Purines Pyrimidines Impossible to know The 4 scientists who discovered DNA structure: Write the last name of the famous scientists. Watson Crick Wilkins Franklin Fill in the blanks - SPELLING COUNTS!! The outside of the DNA molecule is made of of alternating sugar and phosphate. The inner "rungs" of the molecule are the nitrogen bases. Match the bases: The nitrogen bases of DNA ALWAYS pair up the same way. Match the correct bases together. Adenine (A) Thymine (T) Guanine (G) Cytosine (C) DRAW and LABEL Draw a double strand of DNA with 10 bases paired correctly with their complementary bases. Label the 20 nitrogen bases, the hydrogen bonds, the phosphates, and the deoxyribose sugars. Use any order of bases that you wish. Explain how DNA replicates in your own words. Why is this important?
