DNA --> RNA --> protein. Both DNA and RNA can be replicated (i.e. DNA is synthesized from DNA‚ and RNA from RNA). RNA can be made or transcribed from DNA. It is called transcription since the same type of "language" is used in DNA and RNA -- i.e. nucleic acids. In some cases RNA may be used to make DNA (i.e. "reverse transcription") using a particular enzyme called reverse transcriptase. Protein is synthesized from RNA by translation. It is called translation‚ because essentially a different "language"

GENETICS OF DEVELOPMENT. FLOWER DEVELOPMENT REPORT (ARABIDOPSIS THALIANA) INTRODUCTION. Arabidopsis thaliana is the scientific name used to identify a tiny weed whose common name is ‘mouse ear cress’. It is a dicotyledonous angiosperm since its mature embryo carries two leaves (dicotyledonous) and its seeds are contained in an ovary within the flower (angiosperm). Like many other plants‚ Arabidopsis thaliana is an autotrophic plant capable of producing its own food through photosynthesis

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. |

INFORMATION PROCESSING Difference between data and Information Data is raw unprocessed information where as information is data that has been to processed to provide a meaningful value. Information processing is when a machine or processor interacts with the outside world and acts on the input it receives. ADVANTAGES OF INFORMATION PROCESSING * Tasks can be completed faster * Computers can process large amounts of data and generate error-free results. * Computing storage devices

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
