    candidates to explain multiple pituitary hormone deficiency (MPHD) (Chapter 550). There are several distinctive heritable forms of MPHD. Mutations of transcription factor genes that are only expressed in the anterior pituitary lead to simple phenotypes with varying combinations of anterior pituitary hormone deficiencies. Mutations of transcription factor genes that are also expressed in other embryonic tissues give rise to more complex phenotypes that include multiple congenital anomalies. |

    the survival of organisms at all levels. This is much more complex in eukaryotes than in prokaryotes. A major difference is the presence in eukaryotes of a nuclear membrane‚ which prevents the simultaneous transcription and translation that occurs in prokaryotes. Initiation of protein transcription is started by RNA polymerase. The activity of RNA polymerase is regulated by interaction with regulatory proteins; these proteins can act both positively‚ as activators‚ and negatively as repressors. An example

    viruses are called model systems because of their use in studies that reveal broad biological principles. Microbiologists provided most of the evidence that genes are made of DNA‚ and they worked out most of the major steps in DNA replication‚ transcription‚ and translation. Techniques enabling scientists to manipulate genes and transfer them from one organism to another were developed in microbes. In addition‚ viruses and bacteria have unique genetic features with implications for understanding
