Answer

Brief Explanations:

DNA nucleotides have phosphate, sugar and nitrogen - containing bases. Phosphate and sugar form the DNA backbone. Adenine pairs with Thymine via 2 hydrogen bonds, Guanine pairs with Cytosine via 3 hydrogen bonds. A gene is a DNA segment coding for proteins or functional RNA. Eukaryotic cells have a nucleus and membrane - bound organelles, while prokaryotic cells lack a nucleus and most organelles.

Answer:

  1. Nucleotides are made of phosphate group, a sugar, one of four nitrogenous bases.
  2. Phosphate; sugar; sugar.
  3. Adenine; Thymine; Guanine; Cytosine.
  4. A gene is a segment of DNA. It codes for proteins or functional RNA molecules.
  5. Eukaryotic cells: Have a true nucleus, have membrane - bound organelles, larger and more complex. Prokaryotic cells: Lack a true nucleus (have a nucleoid), lack most membrane - bound organelles, smaller and simpler.
