I believe research has many benefits for an application. First of all, it can demonstrate motivation in the sense that you are going beyond what is expected from you. At many schools, research/thesis is not required to graduate, but doing so can set you apart from your peers. In my opinion, going that extra mile speaks volumes. Also, you will establish an important relationship with your advisor, which can benefit you when it comes time to request letters of recommendations. My advisor got to know me beyond a student-professor level. I dined with his family and talked with him about career decisions. I'm sure our relationship helped him write a more personal letter of recommendation. Also, research has helped develop my technical writing skills, critical reading skills, oral presentation skills, and hand-eye coordination. It really has. While I admit it's not fun writing a 60 page thesis or a publication with strict length restrictions, I cannot overlook the fact that writing and reading comes much more easily to me. And this may seem a little lame, but I'm really proud of the research I've done. I like the feeling knowing that I was the first to do this and the first to do that, and get recognition of my work through patents, publications, and presentations.
These are the benefits research has given me. Also, in my experience, every interviewer asked me about my research experiences, and I was happy and proud to explain. AADSAS specifically asks you about it and the schools that I applied to that had secondaries specifically ask about research experiences. I cannot comment on how admission committees feel about no research experience, but I can say in my case, my experience made me stand out among the many qualified applicants this year.
Obviously, I am encouraging you to further investigate research opportunities. And research doesn't have to be in a lab doing "scut" work, as suggested. (Although, I must say that there are many opportunities to work in a lab and do valuable work.) You can research the literature on a specific topic, for example, and write a comprehensive paper. And research isn't limited to chemistry and biology. Maybe you'll have the opportunity to study anthropology in Egypt or research the use of mathematics in codes. I really think there is a research topic out there that can pique your interest!
