PLB 113 – Lecture 2 II. Genome Organization and Gene Expression A. Plants have big (and small genomes) B. Genomes consist of single (LOW) copy and repeated DNA C. How are SC and repeated DNA organized? * Clicker = bonus 100 pt for each question ------------------------------------------------------------------------------------------------ How plants operate the unit? Whole plants <= organs <= tissues <= cell types If we can understand the function of every single cell types in plants, we will be able to understand how plants operate. what the cell does depends on particular set of proteins present in the cell - based on the central dogma (DNA-RNA-protein), it’s the gene expressed in the cell determine how the cell look likes “Differential gene activity underlies cellular and organismal function.” = if we can under all the different genes expressed in different cells, we can understand how the cell works, and by extension, how the organism works. = to know how organism functions, we should know how many genes are expressed What determine what the size of the genome is? What does the nuclear genome (all the DNA present in the nucleus) contain? GENES Does genome contain all the genes expressed in the cell? Yes. Does genome contain all the genes expressed throughout that organism? Yes. (with some exceptions) Genome: has to have all genes in organism. “Differential gene activity underlies cellular and organismal function.” If this statement is accepted as a reasonable statement, the complexity of organisms should be reflected by the number of the genes. More complex the organism is = more number of the genes it has Organismal complexity : number of morphological, behavioral, and physiological parts. Ex. Bacteria < yeast < worm < human
