When entering new questions, KudoZ askers are given an opportunity* to classify the difficulty of their questions as 'easy' or 'pro'. If you feel a question marked 'easy' should actually be marked 'pro', and if you have earned more than 20 KudoZ points, you can click the "Vote PRO" button to recommend that change.
How to tell the difference between "easy" and "pro" questions:
An easy question is one that any bilingual person would be able to answer correctly. (Or in the case of monolingual questions, an easy question is one that any native speaker of the language would be able to answer correctly.)
A pro question is anything else... in other words, any question that requires knowledge or skills that are specialized (even slightly).
Another way to think of the difficulty levels is this: an easy question is one that deals with everyday conversation. A pro question is anything else.
When deciding between easy and pro, err on the side of pro. Most questions will be pro.
* Note: non-member askers are not given the option of entering 'pro' questions; the only way for their questions to be classified as 'pro' is for a ProZ.com member or members to re-classify it.

El patrón de expresión genética obtenido a través de tiempos puntuales
"time points" se puede traducir como "tiempos puntuales". Son momentos específicos en el tiempo en donde se toma una muestra....es un momento ó punto exacto en el tiempo. No confundir con intervalos de tiempo. Intervalo de tiempo es, y valga la redundancia, el tiempo que transcurre entre un tiempo puntual en que fue recogida una muestra y otro tiempo puntual.
Para darte una idea, esos "time points" los podemos llamar "tiempos específicos de recolección de la muestra" ó "puntos específicos entre intervalos de tiempo".
Un ejemplo:
To address the question whether DosR-regulated genes are induced all at once or in a temporal cascade, we exposed M. tuberculosis to a sudden drop of oxygen from a high level of 10% dissolved oxygen tension (DOT) to a low level of 0.2% DOT and extracted samples from chemostat culture to obtain gene expression values from DNA microarrays.
"Samples were taken at nine time points over a period of 25 minutes" and the corresponding DOT recorded. ...
Replicates at time points are often not available in sufficient numbers due to the difficulties in obtaining biological samples. Fortunately, in the case of time course data, regression based methods can borrow information for error estimation across time points [6,7].
Here we outline an analysis strategy based on fitting regression splines with step basis functions to time course data. This method allows us to detect at which time point and hence under which oxygen tension each DosR-mediated gene was induced, providing new insights into the genetic program of DosR mediated gene regulation.

Otra explicación:
"A time point is a point in real, historical time. It is independent of the observer and the context. A time point is not a measurement of time, nor is it a specification of time. It is the point in time. The timepoints at which events occur can be known with various degrees of precision and approximation, but conceptually time points are point-like and not interval-like."
Espero te sea de ayuda.
Saludos!

: "A través de tiempos puntuales" me suena muy mal. ¿Qué es un tiempo puntual? Yo diría "punto temporal", "momento" o, tal vez, simplemente, "intervalo de tiempo". En todo caso, con más contexto (párrafo completo) sería más fácil encontrar la mejor trad.
