Despite the name, the primary modern flavoring ingredients in a cola drink are sugar, citrus oils (from oranges, limes, or lemon fruit peel), cinnamon, vanilla, and an acidic flavorant. Manufacturers of cola drinks add trace ingredients to create distinctively different tastes for each brand.
Features of inbred mice. A strength of the laboratory mouse as a model system results from the availability of hundreds of inbred strains which harbor different characteristics, including some that are prone to develop specific types of cancers.
The retinal degeneration 1 mutation (Pde6brd1, phophodiesterase 6B, cGMP, rod receptor, beta polypeptide) is present in a number of common inbred strains of mice, including some of those used to make transgenic mice (B6SJLF1/J, B6CBAF1/J and FVB/NJ).Pde6brd1 is recessive and causes blindness by weaning.he hybrid mice (B6SJLF1/J and B6CBAF1/J) segregate Pde6brd1 contributed by SJL or CBA. Unless a transgene integrates close to Pde6b, both blind and sighted transgenic progeny may be produced when B6SJLF1/J and B6CBAF1/J are used.
