Study Notes

Genetics

  • Genetics is the study of genes, including how they carry information, how that information is expressed, and how genes are replicated
  • It involves understanding the composition and function of genetic material

Chromosomes and Genes

  • Chromosomes are structures that physically carry hereditary information
  • Chromosomes contain genes, which are segments of DNA
  • Genes encode functional products, such as proteins, that perform specific functions in an organism
