In this chapter, we review mechanisms by which synonymous codon variations influence gene expression at the mRNA or protein levels. These changes may alter the structure and function of the encoded proteins, leading to diseases, altered disease phenotype
Therefore, the present invention also relates to transgenic plant cells containing a nucleic acid molecule of the invention whereby the same is linked to regulatory elements which ensure the transcription in plant cells. The regulatory elements are preferably heterologous with respect to the nucleic acid...
These are known as heavy elements because they are heavier than hydrogen and helium. Although all of these heavy elements are quite rare compared to hydrogen and helium, they are found just about everywhere. [#paragraph3][#highlight3]Heavy elements are continually being manufactured by stars and...
organisms must be buried rapidly to escape destruction by the elements and to be protected (5) agents of weathering and erosion Marine organisms thus are better candidates for fossilization than those living on the land because the ocean is typically the site of sedimentation, whereas the land is...
