- Question
Nucleotides are attached by bonds between the
Options- A. phosphates and sugars
- B. nitrates and sugars
- C. nitrates and phosphates
- D. sugars and hydrates
- Correct Answer
- phosphates and sugars
ExplanationIn DNA, adjacent nucleotides are linked by a phosphodiester bond: a covalent bond is formed between the 5' phosphate group of one nucleotide and the 3'-OH group of another.
Hence, in this manner, each strand of DNA has a "backbone" of phosphate-sugar-phosphate-sugar-phosphate.

Correct Answer: Hyderabad
Correct Answer: exercise effective control over government on a regular and continuing basis
Correct Answer: Polo
Correct Answer: 1900s
Explanation:
On December 12, 1901, a radio transmission received by Guglielmo Marconi resulted in the first transmission of a transatlantic wireless signal (Morse Code) from Poldhu, Cornwall, to St. John's, Newfoundland.
Correct Answer: Force
Explanation:
The term EMF, or Electromotive Force, its use now in decline, is attributed to Italian physicist Alessandro Volta (1745-1827). Today we generally use the term "voltage" - can you guess why we call it that?
Correct Answer: well developed pith
Correct Answer: Squirrel cage motor
Explanation:
The squirrel cage motor is the only one without any connection to the armature.
Correct Answer: 44.1 kHz
Explanation:
CDs reproduce 44,100 samples per second. Which has a maximum frequency reproduction of 22,050 Hz, or just a hair past the upper limit of human hearing. In this way CDs can theoretically reproduce any frequency in the human hearing range.
