LAB 04 EXERCISE 01 o Due No due date e Points 2 e Questions 2 e Time Limit None Attempt History Attempt Time Score LATEST Attempt 1 1 minute 2 out of 2 Score for this quiz: 2 out of 2 Submitted Feb 27 at 4:07pm This attempt took 1 minute. Question 1 1/1 pts (Q001) In Lab 2, Exercise 8, you determined the amino acid sequence for the following strand of DNA: AGCAATCCGTCTTGG TCGTTAGGCAGAACC That strand has mutated. It is now AGCAACCCGTCTTGG TCGTTGGGCAGAACC Use your knowledge of mutation and protein synthesis to answer the following questions. What mutation has occurred? Correct! point mutation movement of large section of chromosome duplication of entire chromosome genetic recombination FEEDBACK: A single base pair of DNA has been altered, which is a mutation known as a point mutation. Genetic recombination is not a type of mutation because it does not create any new genetic material. No large-scale changes such as movement of a large section of the chromosome or duplication of a chromosome have occurred here.

Question 2 Not yet graded / 1 pts (Q002) Will this mutation have a real effect? Why or why not? (Hint: You may want to try Exercise 10 from Lab 2 again, using the mutated DNA strand to make the mutated protein.) Your Answer: A single nucleotide base that is altered, added, or removed is known as a point mutation. In this instance, at position 6, the DNA sequence has altered from "C" to "C C." The protein that is produced from this altered DNA may be significantly impacted by this mutation. The DNA sequence is translated into mRNA, which is subsequently translated into an amino acid sequence, during the process of protein synthesis. A codon is a sequence of three nucleotides that codes for a particular amino acid in mRNA. Quiz Score: 2 out of 2 This quiz score has been manually adjusted by +1.0 points.
