Draw a restriction map of the multiple cloning site of pUC18 that shows how luxAB is expected to ligate into the vector (the map only needs to show the restriction sites used for this set of experiments). For bioluminescence activity to be observed, the genes must get transcribed before they gets translated. Transcription is typically initiated by a transcriptional promoter. What is the difference between what serves as the promotor for lux operon expression in the lux colonies and what serves as the promoter for luxAB expression in luxAB colonies

answer; lower are;

1. the geologists have established a set of principals that can can be used o determine the relative ages of rock. this principal is applied to sedimentary and volcanic rocks. the rocks exposed to wall of grand canyon has layers and by studying the number of horizontal layers in the rock(strata) the relative age can be determined. the layer first formed will appear at the bottom and the the layer of strata last formed appear at the top. by using this information the approximate age of rocks can be determined.

2. carbon dating is used to find the relative age of rock in numbers which means for the rocks that has age between 1-70,000 years.

3. for the rocks of age range between 1,000 - billion of years potassium-argon dating is used.
