Amutation in a gene in the fruit fly drosophila was found to affect eye color. the protein affected was found to be completely normal in its molecular weight and amino acid sequence, although much less of the protein is made in mutant flies. the most likely reason for the change in levels of protein is that the mutation

The mutation did not affect amino acid sequence or the molecular weight (no evidence of amino acid substitution or protein truncation). Therefore, the mutation is not likely within the coding region of the gene.  Most likely the mutation is in the regulatory region of the gene such as the promoter region. Such mutation would interfere with transcription initiation and hence decreases the amount of mRNA and protein produced. 

well we can't tell you because we cant see the time give a screen shot or something.

"-the movement of carbon from the nonliving environment into living things and back to the environment

-carbon is the essential component of proteins, fats, and carbohydrates (which make up all organisms)

-carbon exists in air, water, and living organisms

-producers convert carbon dioxide in the atmosphere into carbohydrates during photosynthesis

-bacteria in the atmosphere cycles through the system in filtration units

-in cellular respiration, carbon is released back into the atmosphere as carbon dioxide

-some carbon is stored in limestone (forming one of the largest "carbon sinks" on earth)

-largest carbon reservoir on earth= limestone

-carbon stored in the bodies of organisms as fat, oils, or other molecules may be released into the soil or air when the organism dies

-this may form deposits of coal, oil, or natural gas (fossil fuels, which increased the atmospheric carbon dioxide)

-fossil fuels store carbon left over from bodies of organisms that died millions of years ago

-they are located in the surface of earth, deep within the earth and beneath the ocean floor."
