Is it ok to take a job now and quit within the first week if a better job comes along later? I work in biotech

This week I got offered a job in biotech I like alot. However, another job, one that I like even better, wants to interview me tommorow. The first job needs to hear back by tommorow as well, so I don't have enough time to go to the interview and then call the first job to tell them if i accept. Should I risk it and take the first job and quit if I do really well with the interview tommorow and they want me to join? I don't want to lose this opportunity for that great job, but I'd be happy with the one that already wants me THANKS!
