Identify the plasmid that must contain the CD3γ core promoter sequence but the fewest or no negative regulatory sequences. Based
on the data in Figure 2, describe the most likely cause of the variation in luciferase activity among the cells that contain plasmids pCD3γ-419 , pCD3γ-309 , pCD3γ-239 , and pCD3γ-199 . Calculate the approximate percent increase in luciferase activity between cells containing plasmid pCD3γ-59 and cells containing plasmid pCD3γ-149 . Round to the nearest whole number.
The plasmid that must contain the CD3y core promoter sequence is PCD3γ-15, and the most likely cause in variation is due to the differing regulatory sequences in the cell.
Out of the choices given, active and passive transport of solutes across a membrane typically differ because active transport always involves the utilization of cellular energy, whereas passive transport does not require cellular energy. The correct answer is B.
Answer: A positron or antielectron is the antimatter counterpart to an electron. A positron has the equal or same mass as an electron and a spin of 1/2, but it has an electrical charge of +1.
Protozoa have been classified into three trophic categories: the photoautotrophs which harness the sun's radiant energy in the process of photosynthesis; the photoheterotrophs, which although phototrophic in energy requirements, are unable to use carbon dioxide for cell synthesis and must have organic carbon compounds
