answer all the options i gavew u
I apologize for the confusion. Here are the answers to all the options you provided:
Question 2: b) resistance to harmful pests
Question 3: The correct order is: 1) duplication, 2) insertion, 3) deletion, 4) inversion, 5) translocation.
Question 4: b) False (genetic mutations can have both positive and negative effects)
Question 5: The diagram is not provided, so I cannot identify the types of mutations.
Question 6: a) CGTT is the sequence of bases on the complementary strand.
Question 7: b) DNA has bases of A, G, C, and T while RNA has bases of A, G, C, and U.
Question 2: The quality that would most likely be selected for in breeding for best crop yields is b) resistance to harmful pests. Farmers would want to breed crops that are resistant to pests in order to minimize damage and maximize yields.
Question 3: The correct order of mutations from top to bottom is 2) translocation, 4) inversion, 3) deletion, 1) duplication, 5) insertion.
Question 4: The answer is b) False. Genetic mutations are not always bad. While some mutations can have negative effects, such as causing genetic disorders, mutations can also have neutral or even beneficial effects, such as providing new variations that can lead to adaptation and evolution.
Question 5: Without a specific diagram provided, it is not possible to correctly identify each type of mutation in the diagram.
Question 6: The sequence of bases on the complementary strand of DNA with a base sequence of TTGC would be b) AACG. In DNA, adenine (A) pairs with thymine (T) and cytosine (C) pairs with guanine (G). Therefore, the complementary strand would have the sequence AACG.
Question 7: The mistake that Tyra made in her chart is b) DNA has bases of A, G, C, and U while RNA has bases of A, G, C, and T. The base thymine (T) is found in DNA, while the base uracil (U) is found in RNA.
