2. DNA is made up of 26 pairs of chromosomes and provides instructions for building an entire organism and proteins.
3. DNA is composed of two chains, which coil around each other to form a double helix carrying the genetic instructions used in the growth.
4. Under the Bill, DNA profiling is allowed only in respect of criminal matters.
Select the correct answer using the code given below :
Answer: C
Statements 1 and 3 are correct, so the answer is Only 1 and 3.
The DNA Technology (Use and Application) Regulation Bill, 2019 sets out to regulate the use of DNA technology for establishing the identity of persons (1), and DNA is indeed a double helix of two coiled strands carrying genetic instructions (3).
Statement 2 is wrong: human cells carry 23 pairs of chromosomes, not 26, and chromosomes are made of DNA rather than the other way round. Statement 4 is wrong because the Bill's schedule allows DNA profiling in civil matters too, such as paternity disputes, immigration, and identifying missing persons and unidentified remains, not only in criminal cases. Every option containing 2 or 4 therefore fails.
