Understanding DNA and Genetics

Genes control how cells function, including growth, division, and lifespan.
Each cell contains 30,000 different genes located on chromosomes, with 46 chromosomes arranged in 2 sets of 23 inherited from parents.
Mutations in genes can cause cells to multiply uncontrollably, leading to cancer.
Genetic mutations can be acquired from factors such as tobacco, UV radiation, viruses, and age, or inherited through germ line mutations.
Tumor suppressor genes protect against uncontrolled cell growth, and oncogenes turn healthy cells into cancerous cells.
DNA repair genes fix mistakes made when DNA is copied, and mutations in these genes may lead to cancer.
Genetic testing can predict a person's risk of certain types of cancer and guide healthcare decisions.
Hereditary cancer syndromes are caused by inherited gene mutations and account for 5-10% of all cases of cancer.
DNA cloning involves isolating and copying DNA to investigate gene function, characteristics, and mutations.
Reproductive cloning creates genetically identical organisms, while therapeutic cloning produces embryonic stem cells for medical treatments.
DNA technology has advanced in fields such as forensics, bioinformatics, pharmacology, and archaeology.
DNA sequencing, PCR, DNA cloning, and gel electrophoresis are common forms of DNA technology used in research and applications.
