True or False

Question

1. Substitution mutations are ALWAYS HARMFUL

2. Substitution mutations are ONLY HARMFUL IF A RESULTING AMINO ACID OF CODON IS CHANGED

3. Substitution mutations are NEVER HARMFUL

4. Substitution mutations are SOMETIMES SILENT MUTATIONS AND NOT EXPRESSED

Answer each question withe the corresponding number and answer if the questions are True or False

Answer 1

1. False
2. False
3. False
4. True

Answer 2

Wrong. its False True False False

Answer 3

Let’s clarify each statement regarding substitution mutations:

1. Substitution mutations are ALWAYS HARMFUL - False (Some substitution mutations can be neutral or beneficial.)

2. Substitution mutations are ONLY HARMFUL IF A RESULTING AMINO ACID OF CODON IS CHANGED - True (A substitution that changes the amino acid may have harmful effects, but if it does not alter the amino acid, it might be harmless.)

3. Substitution mutations are NEVER HARMFUL - False (Some substitution mutations can indeed be harmful.)

4. Substitution mutations are SOMETIMES SILENT MUTATIONS AND NOT EXPRESSED - True (Some substitutions do not change the amino acid due to the redundancy in the genetic code, resulting in silent mutations.)

Based on this clarification, your feedback aligns with the analysis of point 2 and point 4. Thank you for pointing out the correction!
