BIOL 155 Lecture Notes - Lecture 4: Sickle-Cell Disease, Meiosis, Mitosis
Document Summary
A one base-pair mismatch causes sickle cell anemia: normal red blood cells, pro, glu, glu, sickled red blood cells, pro, val (gug instead of gag, glu, one nucleotide mistake in dna. What is biotechnology : use of living organisms to manufacture or modify helpful and functional products for a specific purpose. Biotechnology is everywhere: household products, enzymes in detergent genetically modified, agricultural industry, genetically modify plants, countries that cannot grow crops, medicine, manufacture: wine, beer, cheese, concern of misuse, bad intentions. The evolution of gene manipulation: humans have been using selective breeding for centuries to manipulate genes. Dna technology: dna contains information, editing the information is dna technology, advances in dna technology allow, understanding of mechanisms of life, solving crimes, creating solutions in healthcare. Pcr has revolutionized many fields of biology: scientific research in medicine, diagnosis of genetic defects, detection of aids virus (hiv) in human cells, research in evolution, amplify trace amounts of dna from fossils.
