A Biologist Used Microarrays to Examine How Gene Expression in a Fish

question 196

Short Answer

A biologist used microarrays to examine how gene expression in a fish changes with temperature.Refer to the table showing the expression levels of four (of several thousand) genes at varying temperatures.Values for expression have been normalized such that the expression at 15°C for any particular gene is always 100. The expression of gene(s) _______ steadily increase(s) as temperature increases.
