Molecular Genetics

Molecular Genetics

1. rule of complementary base pairing

2. Genes

   • sequence of nucleotides
   • controls the production of one polypeptide

3. DNA

   • Role of DNA in protein synthesis
   • Nucleotides
     • Deoxyribose (Sugar)
     • Phosphate Group
     • Nitrogen containing base

4. Relationship

   • During cell division, chromatin threads coil tightly into structures called chromosomes in the cell nucleus
     • A molecule of DNA is wrapped around proteins to form a single chromatin thread
       • Each DNA molecule consist of two strands twisted around each other to form a double helix
         • A small segment of the Dna carries a gene that stores information to form a single plypeptides
