Explanation / Answer

1. C (Because genetic information passesonly from parents to their offspring via DNA. The structure of DNA is double helix structure having nucleotide A,T,G,C & deoxyribose sugar because oxygen atom is absent from sugar at 2-C position that's why sugar is deoxy. Option B is wrong because nucleotide U is present in RNA not in DNA.)

2. A (According to Chargaff's rule the purines always paired with pyrimidine that's the reason that A always shows complementary base pairing with T & G always with C.

3. D (Because semiconservative is the mode of replication which produces two copies in which one is copy of original strands second is new strand so we called it as semiconservative .)

4. D (DNA is the cell's genetic material contained in chromosomes within the cell nucleus & mitochondria. A chromosome containes many genes. A gene is a segment of DNA that provides the code to construct a protein. The DNA molecule is a long coiled double helix that resembles a spiral staircase.)
