The discovery of DNA is attributed to the research of three scientists in 1951; Francis Crick‚ Maurice Wilkins‚ and James Dewey Watson. They were all later accredited with the Nobel Prize in physiology and medicine in 1962. Thanks to their discovery‚ science has been able to research and learn from DNA blueprints and use recombinant DNA technology to discover answers‚ vaccines and build immunity for many viruses. In recent years science has been using this new technology to genetically modify animals

functions do transcription and translation carry out‚ and where are they carried out in the cell? Transcription: process of creating an equivalent RNA copy of a sequence of DNA Transcription is the first step leading to gene expression. The stretch of DNA transcribed into an RNA molecule is called a transcription unit and encodes at least one gene. Occurs in nucleus of the cell Translation: Translation is the production of proteins by decoding mRNA produced in transcription. Translation occurs in the

Summary [icon] | This section requires expansion. (March 2012) | During the Nazi occupation of the Netherlands‚ Anne Frank received a diary as one of her presents on her 13th birthday. She began to write in it on June 14‚ 1942‚ two days later‚ and twenty two days before going into hiding with her father Otto‚ mother Edith‚ older sister Margot‚ and another family‚ Hermann van Pels‚ his wife Auguste‚ and their teenage son Peter. The group went into hiding in the sealed-off upper rooms of
