Questions & Step-by-Step Solutions

What type of bond connects nucleotides in a DNA strand?
  • Step 1: Understand that DNA is made up of building blocks called nucleotides.
  • Step 2: Each nucleotide has three parts: a sugar, a phosphate group, and a nitrogenous base.
  • Step 3: Nucleotides connect to each other to form a long chain, which is the DNA strand.
  • Step 4: The connection between the sugar of one nucleotide and the phosphate of the next nucleotide is called a bond.
  • Step 5: This bond is a type of strong bond known as a covalent bond.
  • Step 6: More specifically, the bond that connects the nucleotides in a DNA strand is called a phosphodiester bond.
