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 - SPELLING COUNTS!! 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 -- SPELLING COUNTS! Click on the bubbles to label the molecule -- Just use GENERAL terms from the video.Word Bank: Sugar, Nitrogen Base, Phosphate Group Phosphate Group 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 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) Complete the blanks. DNA Structure:The shape of DNA is known as a Double Helix.The shape looks like a twisted ladder.The phosphate and deoxyribose sugar form the backbone or sides of the DNA ladder, while the nitrogen bases form the steps or middle of the DNA ladder.
