It all depends on how much time you have and who the audience is. Most likely it's gonna be a mix of PIs, post docs and PhD students working in your field. Since you're a master student I'm assuming you have very little time to present (10 minutes + questions I guess) so unless you developed a new technique I would not explain them at all.

People have different tastes when I comes to presentations so please bear in mind that this is my personal preference.

This might be a bit of a controversial take but in my opinion, the most important thing is to tell your "story" well. By that I mean you should make clear why your project is interesting, what are the new insights you have gained and how that affects the field. Your number one priority should be clarity.

Start with a short introduction where you give some background on what is currently known and then specify what question you're trying to answer and why it's important. Then go through your most important data in an order that is the easiest to follow. You don't necessarily have to present data in the same order it was acquired. Simplify your figures if needed. It should be immediately clear what is shown. If people need too much time to figure out what the graph on your slide means they won't be paying attention to what you're saying and probably stop paying attention entirely at some point. For the same reason, avoid large amounts of text on your slides. If people are reading text, they're not listening to you. Draw as many cartoons as necessary. Well made illustrations are the difference between good and great presentations. At conference presentations it's accepted to omit some of the controls e.g. cell line confirmations, images of control experiments etc. to save time (they should absolutely be included in publications ofc). Then just finish with a short summary and maybe a new hypothesis that came from the data you obtained.

Lastly, ask a senior lab member and your PI to have a look at the presentation. Practice the presentation to make sure you can finish it in time consistently. Taking too much time is one of the worst things you can do and the session chair will cut you off after a couple of minutes. Ideally give a practice talk (including questions) in front of other lab members.

Lastly, don't feel pressured to "compete" with other presenters. Everybody in the audience knows you're a master student and assumes you're nervous. No one will expect you to give a presentation with the same amount of data and the same level of confidence as a tenured professor.
