BIO 302 Lecture Notes - Lecture 1: Heredity, Meiosis, Chromosome
Document Summary
The iceland experiment- decode is using the isolated population of iceland in order to determine the function of speci c genes. Genetics: scienti c study of heredity attempt to understand what genes are and how they are passes on. Gene- fundamental unit of heredity made up of dna sequences of nucleotides in dna. Genealogy- the study of families and the tracing of their lineages and history. Genetic code- a,t,c,g, nucleotides codes for amino acids trait- observable property of an organism. Recombinant dna technology- dna fragments are linked to self replicating vectors and replaced in a host cell. ex. Dna fragments from di erent species placed in a host to create new genetic combinations. 75% processed foods in gracer contain ingredients from genetically modi ed plants modi ed to be resistant to herbicides, create novel organisms. Clone- genetically identical molecules all derived from a single source/parent. Gene therapy- normal genes transplanted into humans with defective genes to treat genetic diseases.
