Describe the effect on the protein produced if the DNA coding sequence â€œ-CAA-CCG-GAT-â€œwere miscopied as â€œ-CGA-CCG-GAT-â€�. Concept introduction: A mutation is a shift in a brief area of a genome's nucleotide sequence. Many mutations are point mutations that replace one nucleotide with another; others involve one or several nucleotides being inserted or deleted. Mutations are caused either by DNA replication mistakes or by mutagens' harmful impacts, such as chemicals and radiation, which respond with DNA and alter the structures of individual nucleotides. All cells have DNA-repair enzymes, which try to minimize the amount of mutations occurring. There are two ways these enzymes work, some are pre-replicative, searching for DNA for nucleotides with uncommon structures, replacing them before replication happens; others are post-replicative, checking for mistakes for freshly synthesized DNA, correcting any mistakes, they discover. Therefore, a possible mutation definition is a deficiency in DNA repair.

1. Answer the questions about the following reaction: (a) Draw in the arrows that can be used make this reaction occur and draw in the product of substitution in this reaction. Be sure to include any relevant stereochemistry in the product structure. + SK F Br + (b) In which solvent would this reaction proceed the fastest (Circle one) Methanol Acetone (c) Imagine that you are working for a chemical company and it was your job to perform a similar reaction to the one above, with the exception of the S atom in this reaction being replaced by an O atom. During the reaction, you observe the formation of three separate molecules instead of the single molecule obtained above. What is the likeliest other products that are formed? Draw them in the box provided.

3. For the reactions below, draw the arrows corresponding to the transformations and draw in the boxes the reactants or products as indicated. Note: Part A should have arrows drawn going from the reactants to the middle structure and the arrows on the middle structure that would yield the final structure. For part B, you will need to draw in the reactant before being able to draw the arrows corresponding to product formation. A. B. Rearrangement ΘΗ

2. Draw the arrows required to make the following reactions occur. Please ensure your arrows point from exactly where you want to exactly where you want. If it is unclear from where arrows start or where they end, only partial credit will be given. Note: You may need to draw in lone pairs before drawing the arrows. A. B. H-Br 人 C Θ CI H Cl Θ + Br O
