ANT 100 Lecture Notes - Lecture 4: Macroevolution, Nucleic Acid Double Helix, Nuclear Dna
Document Summary
Recognizes human societies and cultures as biological beings and the social, cultural, physical environments we inhabit. Necessary to understand the process of inheritance (process in which genetic information is passed on from one generation to the next) Microevolution: changes in gene frequencies within a population; smaller scale. Macroevolution: genetics is reason for evolutionary change from one generation to the next, speciation over millions of years; larger scale. Genetics is not the only way humans pass down information, can be passed down through oral and social traditions. Provides genetic code and means to translate code. Provides info for building and operating organisms. Contained in nucleus of cells (ndna) and mitochondria (mtdna) Double helix formed by nitrogenous base pairs which spell out genetic code. Alleles: multiple version of genes coded differently from mother and father. Structures made of protein and dna located in nucleus of a cell. 23 pairs, one from mom and one from dad.
