Life on Earth Chapter 10 DNA: The Molecule of Heredity
At a Glance

The Composition of Chromosomes: DNA is composed of four types of nucleotides.
Is the genetic material DNA or protein?

DNA: The Hereditary Molecule
Bacterial transformation indicates that the hereditary molecule of bacteria is DNA.
The hereditary molecule of bacteriophages is also DNA.
The sequence of bases in DNA can encode vast amounts of information.

The Structure of DNA
The DNA of chromosomes is a double helix.

DNA Replication: The Key to Constancy
The steps of DNA replication are catalyzed by the coordinated action of several enzymes.
Base pairing and proofreading produce almost error-free replication of DNA.; Is the genetic material DNA or protein?
