BLUEPRINT OF LIFE: CHAPTER 2 GENETICS Gregor Mendel’s experiments helped advance our knowledge of the inheritance of characteristics 2.1 GREGOR MENDEL AND THE BIRTH OF GENETICS Gregor Mendel (1822-84) – ‘the father of genetics’ Born in Austria He was an Augustinian monk He worked as a teacher and as an investigator He observed the growth of peas He recorded the ratios of characteristics that appeared in the offspring His discovery stated he observed a pattern in the inheritance of characteristics

that get breast cancer‚ a small amount‚ but there are a few. There are many causes to this cancer‚ which come from inherited genes (DNA) that can cause normal breasts to become cancerous because the developing cancer and cause run through families. For instance‚ BRCA1 and BRCA2 are tumor suppressor genes‚ which keep the cancer tumors from forming‚ but when mutated‚ these genes die and cancer is more likely to develop [ (Learn About Cancer‚ 2010) ]. Although scientists do not know the exact reason

Undifferentiated carcinoma: Cancer cells that do not look like normal cells and multiply uncontrollably. What is lung cancer? Lung cancer is the accumulation and uncontrolled growth of abnormal cells in the lung. This wild reproduction forms tumours that clog up the lung and stop it from functioning properly. Lung cancer is the leading cause of cancer deaths for both men and women in Canada. Exposure to substances such as Asbestos and Arsenic Drinking water high in substances such as arsenic

circular chromosome. Its genome has a total of 5.7 million base-pairs‚ with 2.8 million residing on its circular chromosome and 2.1 million residing on its linear chromosome and although most of the genes essential for its survival are located on the circular chromosome; through evolution some essential genes have migrated to the linear chromosome. Based on sequence analysis‚ it was determined that the linear chromosome was derived from a plasmid that was transformed into the bacteria. The ends of

The three popular aspects of biotechnology are IVF‚ Gene Therapy and Cloning and will be covered in relation to the future of us humans. One example of biotechnology is IVF (In Vitro Fertilization) which is a method where an egg is fertilised by sperm outside the body. This process takes several weeks

cyclin-CDK complexes. This activation triggers cell-cycle events. Cellcyclecontrol/ inhibitors: Two families of genes‚ the cip/kip family and the INK4a/ARF (Inhibitor of Kinase 4/Alternative Reading Frame) prevent the progression of the cell cycle. Because these genes are instrumental in prevention of tumor formation‚ they are known as tumor suppressors. The cip/kip family includes the genes p21‚ p27 and p57. They halt cell cycle in G1 phase‚ by binding to‚ and inactivating‚ cyclin-CDK complexes. p21

Cancer is a genetic disease‚ caused by changes to genes that control the way our cells function‚ especially how they grow and divide. Genetic changes that cause cancer can be inherited
