CHAPTER 21 AP BIOLOGY D) the ability to produce both egg and sperm E) knowledge of the organism 7) Of the following, which has not proven to be a useful model organism in the study of developmental genetics? A) Caenorhabditis B) humans C) mice D) Arabidopsis E) Drosophila 8) The nematode Caenorhabditis elegans is used as a model organism for genetic studies. One of the key advantages of using Caenorhabditis elegans for study is that A) its genome is as large as ours. B) it has a great variety of somatic cells. C) early stages of development proceed quickly. D) it is hermaphroditic, making it easy to detect recessive mutations. E) morphogenesis and growth occur throughout life. 9) The process of cellular differentiation is a direct result of A) cell division. B) morphogenesis. C) differences in cellular genomes. D) differential gene expression. E) induction. 10) The cloning of a plant from somatic cells is consistent with the view that A) the differentiated state is normally very unstable. B) genes are lost during differentiation. C) differentiated cells retain all the genes of the zygote. D) differentiated cells contain masked mRNA. E) cells can be easily reprogrammed to differentiate and develop into another kind of cell. 11) The ability of a transplanted nucleus to support development A) depends on the DNA base sequence. B) only occurs in plants.
