Examples
-
In the counting project, which was published in the journal Science in May, Dr. Collins and his colleagues programmed bacteria to emit a fluorescent protein after being exposed three times to a sugar called arabinose.
-
The T7 RNAP primes the E. coli to create a different protein, T3 RNAP, when the bacteria are exposed to a second pulse of arabinose.
-
If the mixture contains arabinose and the indicator dye, the difference between Ara+ and Ara− is revealed, as if by heating invisible ink: they show up as white and red colonies, respectively.

They are rich in a mucilage, which on hydrolysis yields eight sugars, the pre dominant ones being d-galactose and l-arabinose in the ratio 8: 1.

Observations on the pure pentoses -- xylose and arabinose added to dextrose solutions, and then exposed to yeast action -- show that in a vigorous fermentation not unduly prolonged the pentoses are unaffected, but that they do come within the influence of the yeast-cell when the latter is in a less vigorous condition, and when the hexoses are not present in relatively large proportion.
