Luciferase is a protein (enzyme) that is produced by fireflies and catalyzes a reaction allowing them to “glow” at night.
why might it be useful to scientists to learn the genetic code for the production of luciferase?

Luciferases are widely used as reporter gene in the study of promoter sequences of genes, they are also at the origin of the method of ATPmetry. as well as in pyrosequencing: ATP sulfurylase then converts this pyrophosphate (PPi) to ATP which is then used, coupled to a luciferin, by a luciferase. Oxyluciferin and a light signal are then produced.

the answer is z.

the human body has five levels of organization. level 1: cells. cells are the basic units of life and form the first level of organization. cells in the human body have specific functions. examples include nerve cells, blood cells, liver cells, and so on.
