Calculate the energy in J of a photon of light with a wavelength of 295.1 nm (show work for full credit) c = 3 x 108 m/s              h = 6.626 x 10-34 J s/photon

Once transcription has initiated, RNA polymerase transcribes until it reaches the end of the chromosome and releases.

Solve the logarithmic equation for x. Give an exact solutionlog3(x + 6) – log3(x – 2) = 3

1.00 L of water initially at 25 oC was heated to 50 oC. How much energy in kJ was absorbed by the water? The heat capacity for water is 4.18 J/goC.  (DensityH2O = 1g / mL)

Alternative RNA splicing can allow the production of proteins of different sizes and functions from a single mRNA.

Which of the following is not used as a heterologous host for the expression of recombinant proteins?

Desirable features of a modern radiographic table consist of which of the following?1.   High-attenuation tabletop material2.   Variable height3.   Four-way floating tabletop4.   Radiolucent tabletop5.   Convenient and ergonomic-friendly controls6.   Foot control of table motions

The tRNA macromolecules contain the codons.

The genetic code is essentially the same for all organisms. From this, one can logically assume that the same codons in different organisms translate into different amino acids.

A 14-year-old presents to the clinic complaining that they have been having chest pain with accompanying shortness of breath and subsequent numbness in both arms. These events have occurred only at school prior to examinations and oral presentations. The patient states that they feel like they are going to “pass-out” during these events. The history and examination reveals a well, 14-year-old with no underlying family history of sudden cardiac death and no past medical history of underlying cardiac issues. What should the nurse practitioner explain to the patient and the parent about their symptoms?
