PPT-15.1 – Genetic Comparisons Using DNA

Learning objectives Students should understand the following Genetic comparisons can be made between different species by direct examination of their DNA or of the proteins encoded by this DNA Comparison of DNA base sequences is used to elucidate relationships between organisms These comparisons have led to new classification systems in plants. Comparing more than two means and figuring out which are different. Analysis of Variance (ANOVA). Despite the name, the procedures compares the means of two or more groups. Null hypothesis is that the group means are . “. Engineering. ”. for Crop Improvement. Xiwen Cai. North Dakota State University, Fargo, ND. Outline. Definition of genetic engineering. Genetic engineering at the whole . plant level. Genetic engineering at the cell level. Mutation. Permanent change in the genetic material of an organism. All mutations in gametes are inheritable because they are copied during DNA replication. Somatic cell mutations occur in body cells. . Content. Comparisons using: ‘the same as’, ‘similar (to)’, ‘different (from)’. Comparisons using ‘like’ and ‘alike’. The comparative using ‘-er’ and ‘more’. The superlative using ‘est’ and ’most’. 7.
