BIOL 2021 Chapter Notes - Chapter 1: Reverse Genetics, Dna Replication, Rna Splicing
Document Summary
All life begins as a single cell that is fertilized by an egg and sperm. All multicellular cells undergo fertilization of a zygote adult. When cells divide, they produce new cells that are physically and chemically different thus have different functions i. e. blood cells, secretory cells, nerve cells, etc. Events of translation is to occur in order to read out the gene. Genetics: study of diversity, replications, mutations, translation (the 4 properties above) 15th c. gregor mendel was the first to discover genetics: studied pea garden and noted that there were factors that were inheritable from parent to offspring. 20th c. information specifying development was contained in the chromos in nucleus. Crosses between differing variants which are inheritable correspond to chromo distribution into gametes at meiosis. Genes on chromo are responsible for information of characters: affects every aspect of structure and function of an organism.
