The phrase "a expression which" is not correct.
It should be "an expression which." You can use it when introducing a specific expression or phrase that you want to explain or elaborate on.
Example: "I came across an expression which perfectly captures the essence of the situation."
Alternatives: "a phrase that" or "a term which".
Our study is fundamentally different from those previous studies, as we neither studied the total amount of cyclin E in the tissue nor just the number of cells staining for cyclin E. Instead, we focused on how cyclin E is expressed in relation to cyclin A expression, which is likely to be related to how cyclin E is expressed over the cell cycle.
Future studies should elucidate whether the alteration of GABA A expression, which is observed during CHC infection, has an impact on the development of hepatocellular carcinoma.
On the other hand, the channel with the size of 500 μm enhances VEGF-A expression, which benefit the development of large vessels.
An alternative hypothesis is that stable cell lines have undergone long-term adaptation to altered CENP-A expression, which has led to re-equilibrated centromeric levels.
PANC-1, LPC006, LPC028 and LPC167 cells were selected for further studies due to their levels of LDH-A expression, which were representative of high, low, extremely high and median mRNA values, respectively.
The reader may be accustomed to thinking of a formula as an expression which plays the role of an assertion in a formal language, and of a term as an expression which designates an object.
If they were a person they would be wide-eyed, with a slacked jaw and a mouth in an O-shape, an expression which aforementioned series stalwart Kenneth Williams regularly found himself in.
A waste of space is an expression which means a thing is completely without value.
That is, it is given by an expression which is a rational function of its argument and some of the derivatives of the argument.
The purpose of developing this approximation is to estimate BER with an expression which is a computationally simple function of the equalizer weights.
In this programme we have an expression which means 'to make a great effort to achieve something'.
