Why bacteria gene was found in a ligation after transformation analysis?

Hi everyone, I am doing a conventional cloning ligation procedure using double digestion (BamHI and EcoRI) using pGEX-6P-1 vector with my purified PCR product of 393bp. After ligation in 6:1...

Is multicollinearity a problem in regression model with big data?

I asked this because according to Gujarati (1995), one of the remedial measures to mitigate the problem of multicollinearity is to increase the sample size. Thus, can we say that multicollinearity...

Physics: Why do we describe light by referring to its wavelength, but microwaves and radar pulses by referring to their frequency?

In physics, the description of the properties of light generally refers to its wavelength (nm), while in the range of microwaves and radio waves we refer to the frequency of a signal (e.g. kHz or...

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...

Why almost every element would be metallized in sufficiently high pressure and low temperature?

(This statement is from wikipedia, BTW). What is so special about metallic bond that is limiting high-P low-T state of a matter (as long as individual atoms exist, not white dwarf of neutron star...

What is the state of the drug inside solid lipid nanoparticles (SLNs)?

I am a little confuse with the mechanism of solid lipid nanoparticles (SLNs). The main point of encapsulating drugs into SLNs is because some drugs have low solubility in water. Therefore, SLNs...

Should we reduce the standard unit of length to 0.31951540592 meter ?

The reasoning behind this question is to align the ratios of the proton potential in energy per charge to the speed of light in distance per time. As these two dimensions appear to be related,...

No streamlines present in a small region inside a flow. This means exactly what?

No streamlines present means whether the flow is getting obstructed there and the velocity inside the region is zero? Or else, the fluid is trapped inside that region with a nonzero velocity?...
