Molecular Basis of Inheritance

List-I | List-II (a) Bacteriophage φ × 174 | (i) 48502 base pairs (b) Bacteriophage Lambda | (ii) 5386 nucleotides (c) Escherichia coli | (iii) 3.3 × 10^9 base pairs (d) Haploid content of human DNA | (iv) 4.6 × 10^6 base pairs Choose the correct answer from the options given below :

  1. (A)(a)-(i), (b)-(ii), (c)-(iv), (d)-(iii)
  2. (B)(a)-(i), (b)-(ii), (c)-(iii), (d)-(iv)
  3. (C)(a)-(ii), (b)-(iv), (c)-(i), (d)-(iii)
  4. (D)(a)-(ii), (b)-(i), (c)-(iv), (d)-(iii)

The NCERT line that answers it

Verbatim line

For example, a bacteriophage known as $\phi \times 174$ has 5386 nucleotides, Bacteriophage lambda has 48502 base pairs (bp), *Escherichia coli* has $4.6 \times 10^6$ bp, and haploid content of human DNA is $3.3 \times 10^9$ bp.

Chapter
Molecular Basis of Inheritance
Section
5.1 THE DNA

The answer appears as a continuous sentence in NCERT. This is that sentence.

How this line gives the answer

0, emb=1.0, combined=1.0). Verified: high — The NCERT span explicitly lists all four specific numerical values that match option D: φ×174 has 5386 nucleotides (matches a-ii), Bacteriophage lambda has 48502 bp (matches b-i), E. coli has 4.6×10^6 bp (matches c-iv), and haploid human DNA has 3.3×10^9 bp (matches d-iii).

We did this for 1,565 questions.

Every one traced to the exact sentence in NCERT that answers it, including 90% of the 2026 paper. Sit a mock on the real NEET 2027 computer interface and every mark you drop comes back with its line attached.
