WLHS/Biology/Oppelt Name: Timothy Lucero WEBQUEST – DNA and Protein Synthesis You will be visiting multiple websites. At each website, read the material and answer the following questions that coincide with that section. PART 1: DNA and Protein Synthesis Go to: . Under Genetics, select Molecules of Inheritance. Then select Build a DNA Molecule Activity. 1. In the space below, draw the strand of DNA you created (letters only, both strands). You will need to write down the bases as you drag them to the complementary base pair. Go back to the Molecules of Inheritance page by clicking the back arrow. Then select Transcribe and Translate a Gene (on the right hand side under Central Dogma) Scroll down the page and read the information on transcription and translation. Then answer the questions below. 2. a. What is a gene? G enes encodes a unique protein that performs a specialized function in the cell b. How many does the human genome contain? The human genome contains about 21,000 genes 19,000 - 20000 3. a. In which organelle does transcription occur in? I n the nucleus In a eukaryotic cell, transcription occurs in the nucleus, and translation occurs in the cytoplasm b. What is the role of mRNA? A molecule that is similar to DNA , messenger RNA is responsible for transporting RNA to ribosome for translation
c. Which base is thymine replaced by? T he base uracil (U) replaces thymine (T) 4. a. Where are proteins made? T
