The Central Dogma. This hypothesis was described by Crick in 1958. In 1953‚ Watson and Crick were the first to determine the true crystalline structure of DNA‚ using model building and then X-ray crystallography. Once the DNA structure was determined‚ the mechanisms behind inheritance‚ information flow‚ and gene function fell into place. Overall the flow of information is depicted as: DNA --> RNA --> protein. Both DNA and RNA can be replicated (i.e. DNA is synthesized from DNA‚ and RNA from RNA)

This opposed many traditional views as it was generally accepted that the beginning inhabitants of the world had no mutations in their genetic composition. His publication had two major points.

Clinton and Richmond’s (2009) publication defines Transgenic Animals as those animals that have had their genome altered deliberately to help serve a better purpose to mankind. A review of the literature covering the process provides insight into the wide use of these animals and the five main categories and their specific and important use. Such animals assist

A ’tropism’ is a growth in response to a stimulus. Plants grow towards sources of water and light‚ which they need to survive and grow. Auxin is a plant hormone produced in the stem tips and roots‚ which controls the direction of growth. Plant hormones are used in weedkillers‚ rooting powder and to control fruit ripening. Tropisms The direction of plant growth Plants need light and water for photosynthesis. They have developed responses called tropisms to help make sure they grow towards sources

It has a number of characteristics: It is a triplet code- three bases code of an amino acid It is a degenerate code- All amino acids bar one have more than one code Some codes don’t code for amino acids

The language of science actively constructs scientific reality‚ i.e. a way of looking at the world‚ the roles assigned to readers and the way of organizing information (LING337-nominalisation).
