Consider the following simplified model of a DNA molecule resembling a molecular 'zipper': A long chain of two parallel strands, each strand being a linear chain of four basic molecular units, namely, bases called A, T, G and C (see figure below).
DNA PAPER MODEL: HOMEWORK QUESTIONS Analysis Questions: 1. What base does adenine pair with? 2. What base does guanine pair with? 3. Describe the shape of the DNA molecule. Draw a picture if it helps! Connections: 1. What are the three components of a nucleotide? (HINT: What were the three components used in putting the model together? Remember.
Add all the key words you need to answer the Big Question in this box. Explain what DNA is and how the model of DNA developed. You should include information on how genetic information is carried, as well as the role of different scientists involved in the development of the DNA model. (QWC, 6 marks).
All cells have DNA errors due to the mistakes that occur each time DNA is replicated prior to cell division. There are proofreading enzymes in cells that correct many of these mistakes, but on average, 3 - 5 errors are found in DNA after each replication. a. If each cell has multiple mutations, why do most of us have normally-functioning tissues and organs? c. 7. b. Why is only a tiny subset.
