 Golden rice

The transgenic rice, popularly called "golden rice" contains good quantities of carotene, which gives the grains a golden colour. In one transgenic line, the β-carotene content was as high as 85% of the total carotenoids present in the grain.

In proteins, there are three types of chromophores relevant for UV/Vis spectroscopy:

peptide bonds (amide bond);

certain amino acid side chains (mainly tryptophan and tyrosine); and

certain prosthetic groups and coenzymes (e.g. porphyrine groups such as in haem).

Each DNA helicase moves along ssDNA in a defined direction. This property is referred to as the polarity of the DNA helicase. DNA helicases can have a polarity of either 5’->3’ or 3’->5’.
