== Vakinformatie ==&lt;br /&gt;
Dit vak wordt gegeven door Prof. Arnout Voet. Er zijn enkele dingen veranderd in 2022 vergeleken met de ECTS fiche. Doorheen het semester zijn er enkele verplichte sessies waarbij je de basis leert van werken in UNIX en een molecular dynamics simulation uitvoert, voor aanwezigheid krijg je dan ook punten (ik dacht 1 of 2 op 20, niet zeker). Je moet ook een taak indienen (5/20 punten) waaraan gewerkt wordt tijdens de lessen.&lt;br /&gt;

&lt;br /&gt;
2. You have the structure of a receptor and a few active ligands that inhibit a receptor. There is no structure of the complex. The ligands inhibit the receptor but can not be used as drug.

&#039;&#039;&#039;Exam of 16/01/2023&#039;&#039;&#039;&lt;br /&gt;
&#039;&#039;   (This exam was written instead of oral, due to the Covid-19 restrictions. One open question was replaced by multiple choice questions.)&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
1. 15 multiple choice questions about the entire course. There was one question for each of the papers. (15)&lt;br /&gt;
&lt;br /&gt;
2. You have the structure of a receptor and a few active ligands that inhibit a receptor. There is no structure of the complex. The ligands inhibit the receptor but can not be used as drug.

Gedoceerd door Professor Nies en Professor Koeckelberghs. Lessen zijn altijd in het Engels. De verdeling is 2/3 op het deel van Nies en 1/3 op het deel van Koeckelberghs. Bij Nies zijn er ook verplichte assignments tijdens het jaar, die meetellen voor een fractie 4/(12-N) van de punten van zijn deel (met N aantal assignments, doorgaans 2). Nies zijn examen is gesloten boek en er moet maar één vraag bij hem mondeling besproken worden (deze wordt op voorhand aangeduid). Bij Koeckelberghs zijn alle vragen mondeling te bespreken.&lt;br /&gt;
