Questions & Step-by-Step Solutions

What is the structure of DNA primarily composed of? (2023)
  • Step 1: Understand that DNA stands for Deoxyribonucleic Acid.
  • Step 2: Know that DNA is made up of smaller units called nucleotides.
  • Step 3: Each nucleotide has three parts: a sugar, a phosphate group, and a nitrogenous base.
  • Step 4: The sugar in DNA is called deoxyribose.
  • Step 5: The phosphate group helps link the nucleotides together.
  • Step 6: The nitrogenous base can be one of four types: adenine (A), thymine (T), cytosine (C), or guanine (G).
  • Step 7: These nucleotides connect in a specific way to form the structure of DNA.
