Is there a mutation in Maggie's DNA sequence? If so, what type of mutation did you find? 3. What change has occurred in Maggie's CFTR protein? 2. Draw the following structures [ \( \mathbf{1 5} \) marks] A. An Oligosaccharide made up of Galactose, Glucose and Fructose such that : Galactose is joined to Glucose by a \( \beta(1 \rightarrow 4) \) glycosidic bond (anomeric carbon of Galactose is key in forming this bond) and then Glucose is also attached to Fructose by a \( \alpha \beta(1 \rightarrow 2) \) glycosidic bond (in this case the bond links the anomeric carbon of Glucose to the anomeric carbon of Fructose) [8 marks] B. A peptide made up of Alanine, Tyrosine, Lysine, Cysteine and Glutamate (These amino acids are of course held together by peptide bonds) [7 marks] How are the DNA strands pushed through the gel in the process of electrophoresis? By adding an electrical current Using gravity Manually, by hand By being put in a dark room Question 1 (1 point) Because DNA strands are so tiny, how do scientists sort and measure them? They sort them by hand They use a microscope and probes They use gel electrophoresis Thevuse a centrifuoe Question 2 (1 point) In this lab, DNA strands are sorted by width length color species 4. How is the total magnification of a microscope found? subtracting the eyepiece and objective lens magnification adding the eyepiece and objective lens magnification multiplying the eyepiece and objective lens magnification multiplying the magnification for each objective lens 3. Which type of microscope provides the best three-dimensional view of an object? electron microscope dissecting microscope compound microscope magnifying microscope What makes gametes different from other body cells? They do not go through the process of meiosis. They do not carry genetic information. They contain half the number of chromosomes. They contain double the number of chromosomes. 3. How many chromosomes are in human cells, excluding gametes? 30 92 23 46
