Genetic Mutations Instructions: Complete the following by watching the Bozeman Video at http://www.bozemanscience.com/mutations 1. What are mutations? Changes in DNA. 2. Why are mutations bad? They can cause changes in DNA that result in changes in mRNA and eventually proteins, meaning it changes you. 3. What is a point mutation? A mutation that only affects a single nucleotide of nucleic acids. They commonly involve the substitution of one base for another. 4. What are the two ways mutations happen? What is the difference between them? Two ways mutations happen are by spontaneous mutations and induced mutations. A spontaneous mutation means that something in the process of replicating DNA or forming gametes goes wrong and an induced mutation is caused by the environment. 5. How does smoking cause cancer? Smoking causes cancer because mutagens fit into the double helix, causing a mutation in the DNA in an area where we have cancer suppressing jeans. 6. What is a substitution mutation? Is this always a big deal? A substitution mutation is when the wrong letters are being replaced. If the letter is not inside a Jean it’s no big deal, but if it’s inside a gene where we create amino acids to make proteins, it can cause bigger problems. 7. What is insertion mutation? An insertion mutation is where you take one chromosome and insert it into another chromosome. 8. What is a deletion mutation? A deletion mutation is where we are missing huge chunks of chromosome, which could be hundreds if not thousands of genes. 9. During meiosis or mitosis other mutations can occur. What are the names of these mutations and what happens to the genes? Duplication mutations duplicate a portion of jeans during the ass face. Inversion mutations copy the jeans but they are being flipped upside down. Translocation mutations take a chunk of a chromosome and move it to another and vice versa.
