General Science problems
- 1. What are the sides of the dna ladder made of
Options- A. nitrates and sugars
- B. sugars and hydrates
- C. sugars and phosphates
- D. phosphates and nitrates Also asked in: AIEEE, Bank Exams, CAT, GATE, Analyst, Bank Clerk, Bank PO, IT Trainer
Correct Answer: sugars and phosphates
Explanation:
DNA is a double-stranded molecule twisted into a helix. The shape of DNA is a double helix, which is like a twisted ladder. The sides of the ladder are made of alternating sugar and phosphate molecules. Deoxyribose, which is a pentose, and a phosphate group are the two molecules together form the two sides of the DNA. The rungs of the ladder are pairs of 4 types of nitrogen bases.

- 5. Which of the following CANNOT be considered a single phase?
Options- A. a heterogeneous mixture
- B. a pure solid
- C. a pure liquid
- D. a homogeneous mixture Also asked in: AIEEE, Bank Exams, CAT, GATE, Analyst, Bank Clerk, Bank PO
Correct Answer: a heterogeneous mixture
Explanation:
A pure solid and a pure liquid are definitely a single phase because they are so united, or homogeneous. This leads to a homogeneous mixture also being a single phase.
Hence, the option that cannot be considered a single phase is A. a heterogeneous mixture.

Options- A. Monetary experiment
- B. Lunar experiment
- C. Montreal experiment
- D. Monsoon experiment Also asked in: AIEEE, Bank Exams, CAT, GATE, GRE, Analyst, Bank Clerk, Bank PO
Correct Answer: Monsoon experiment
Explanation:
Monsoon experiment is abbreviated as MONEX.
The Monsoon Experiment is the core of the GARP Monsoon Subprogramme, which is a major international effort to achieve a better understanding of the Planetary monsoon circulation, the major seasonal perturbation of the general circulation of the atmosphere and the influence of the annual cycle of precipitation associated with the monsoon on the agriculture of the many populous nations of the region.
Hence, MONEX is associated with The Monsoon Experiment.
