Question 28
'All mutations are harmful.' Discuss this statement.
Worked Solution & Example Answer:'All mutations are harmful.' Discuss this statement. - HSC - SSCE Biology - Question 28 - 2004 - Paper 1
Step 1
Discuss the harmful effects of mutations
Answer
Mutations can indeed have harmful effects on organisms. For example, a mutation might lead to a malfunctioning protein, which can disrupt essential biological processes and lead to diseases such as cancer. Other harmful mutations can result in genetic disorders that impact an organism's development or function.
Step 2
Discuss the beneficial effects of mutations
Answer
Contrarily, not all mutations are detrimental. Some mutations can be beneficial, providing an advantage to the organism. For instance, a mutation in a bacterium may confer resistance to antibiotics, allowing it to survive in harsh conditions. Additionally, mutations are essential for evolution, driving genetic diversity and adaptability in populations.
Step 3
Conclusion
Answer
In conclusion, the statement 'All mutations are harmful' is an oversimplification. While there are harmful mutations, many can be neutral or beneficial, playing a crucial role in evolution and adaptation. A balanced view recognizes that the effects of mutations are context-dependent.
