Unformatted text preview: BIO 325 Genetics Lectures 2 and 3 Chromosome Organization and Molecular Structure The Deepest Sensuality by D.H. Lawrence The profoundest of all sensualities is the sense of truth and the next deepest sensual experience is the sense of justice. Chromosome Organization and Molecular Structure Chromosome Organization and Molecular Structure Chromosomes are the structures that contain the genetic material. Chromosomes are the structures that contain the genetic material. They are complexes of DNA and proteins. Chromosome Organization and Molecular Structure Chromosomes are the structures that contain the genetic material. They are complexes of DNA and proteins. The genome comprises all the genetic material that an organism possesses. Chromosome Organization and Molecular Structure Chromosomes are the structures that contain the genetic material. They are complexes of DNA and proteins. The genome comprises all the genetic material that an organism possesses. In bacteria, it is typically a single circular chromosome. Chromosome Organization and Molecular Structure Chromosomes are the structures that contain the genetic material. They are complexes of DNA and proteins. The genome comprises all the genetic material that an organism possesses. In bacteria, it is typically a single circular chromosome. In eukaryotes, it refers to one complete set of nuclear chromosomes. Chromosome Organization and Molecular Structure Chromosomes are the structures that contain the genetic material. They are complexes of DNA and proteins. The genome comprises all the genetic material that an organism possesses. In bacteria, it is typically a single circular chromosome. In eukaryotes, it refers to one complete set of nuclear chromosomes. The main function of the genetic material is to store information required to produce an organism; the DNA molecule does that through its base sequence.
