Answer:
1. A nucleotide is made up of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine
2. Four different types of nitrogenous bases are found in DNA: adenine (A), thymine (T), cytosine (C), and guanine (G).
3. The nitrogen bases are ring compounds with their carbon and nitrogen atoms arranged in single or double rings. Only certain bases can pair together to form base pairs. In DNA, Adenine (A) always pairs with thymine (T), and guanine (G) always pairs with cytosine (C).
Answer: 1. The sugar, base, as well as the phosphate. 2. Adenine, Thymine, Guanine, Cytosine, and the Uracil. 3. The nitrogenous bases form hydrogen bonds between opposing DNA strands to form the rungs of the "twisted ladder" or double helix of DNA or a biological catalyst that is found in the nucleotides.
