Properties of Genetic Material — NEET Biology
✅ Asked in NEET 2016It should be able to generate its replica (Replication). (ii) It should be stable chemically and structurally. (iii) It should provide the scope for slow changes (mutation) that are required for evolution. (iv) It should be able to express itself in the form of 'Mendelian Characters'.
NTA tests whether students understand the four essential properties that define an ideal genetic material: replication ability, chemical stability, capacity for mutation, and expression as traits. Students often memorize these properties without understanding their significance—for example, confusing 'stability' with 'immutability' or failing to recognize why mutation is necessary despite requiring stability. Remember: genetic material must be stable enough to preserve information across generations but flexible enough to allow mutations for evolution. DNA satisfies all four criteria, making it the universal genetic material. Focus on why each property matters functionally, not just listing them.
