Classification of genes

Thesis: Genes can be divided into separate groups by various features and functions and this helps in analyzing the aging processes.

Type of classification

• Flat tree - all classes belong to the same level, no super classes and subclasses.
• Nested tree - several levels of hierarchy.

Nested tree example:

• Nuclear genes
  • RNA genes
    • rRNA genes
    • tRNA genes
    • miRNA genes
  • Protein genes
    • Protein type1 genes
    • Protein type2 genes
    • ...
• Mitochondrial genes

Classifications

• By sequence similarity (Dayhoff, 1978)
• By protein function
• By location on chromosomes (suggested - denis.s)
• By localization in cell of the end protein (suggested - denis.s)
• By the end product - protein or RNA (suggested - denis.s)
