You are excited because your lab is studying the first microorganisms retrieved from mars! interestingly, their genetic material consists of a single-stranded nucleic acid with six different nitrogenous bases. like organisms from earth, segments of the nucleic acid contain the code for making proteins. if the genetic code in these organisms was read in groups of 2 bases instead of 3, what is the maximum number of amino acids that could be coded for assuming that only one codon functioned as a stop codon?

Ascientist is investigating the effects of salinity on fish development. he places fertilized fish eggs in an aquarium that contains low salinity and observes their development. what factor would improve experimental design the most? place the fish eggs in the open ocean because that is the natural habitat include another aquarium that has normal salinity to compare to the low salinity aquarium include an aquarium that replaces salt with sugar to confirm that the effects are specific to salt grow algae with the fish eggs in order to provide adequate nutrients to the developing embryos
