Resumo de Recurso

12-2: DNA Replication and Chromosomes
  1. Chromosomal Structure
    1. Chromatin: substance, tightly packed DNA and proteins
      1. Proteins are called "histones"
      2. Nucleosome: bead-like structure, DNA and histone
        1. Nucleosomes have some DNA and histones
      3. DNA Replication
        1. occurs in many places, proceeds in both directions until DNA is completely copied
          1. complementary strands: strands that can be used for production of other strands
            1. DNA molecule separates, produces two new complementary strands following rules of base-paring
              1. DNA Polymerase: enzyme used in replication
