What is the difference between transcriptional and translational fusion?
As I understand it, transcriptional fusion places a reporter, like lacZ, downstream of the promoter of your gene of interest (so it does not include your entire gene). Is this the same thing in a translational fusion...
An asteroid with a diameter of 500km has an impact strength of 4000J/kg. What is the largest sized crater diameter which can be formed without melting the asteroid? The asteroid has a density of 3.5 g/cm^3 and the impact velocity is 5km/sec
I have a few formulas:
The asteroid will...
When the free-radical bromination of propane is carried out in the presence of chlorine, the bromination selectivity (ratio of 1-bromopropane to 2-bromopropane) is much lower than it is when chlorine is omitted from the reaction (In other words, chlorine changes the observed ratio of...
You are visiting a new planet with radius of 5000km. You set up a seismic network and detonate a test chare at the north pole at time T=0. At time T=24minutes your instruments detect S-waves at a latitude of -60 degrees. No S-waves are detected south of -60 degrees.
what is the size and...
You find a meteorite and measure a rubidium-strontium age of 4.5 billion years. However, the gas retention age of the meteorite is 1.5 billion years, and the cosmic ray exposure age of the meteorite is 10 million years. When did the meteor form? How can you reconcile the three different age...
You are traveling through space and come upon a solar system having a star like the Sun, but with planets being extremely rich in calcium, aluminum, titanium. How were the formation conditions different from our solar system?
Attempt at solution: The supernova that created this solar...
I'm given the six orbital parameters for a comet and am asked to find how close it comes to earth, but I'm not sure how to go about this...
Should I calculate the position of the comet and Earth and the comet's perihelion passage? If so, are there equations for this type of thing?
The...
