I had a question about how the RNA processing occurs. I know that the RNA is transcribed off the DNA, and then the introns are removed(sometimes in different orders), and then the capping occurs. My question is whether or not different segments of RNA can fuse together before during the processing. My idea is that you have all these RNA segments, and say apart of the RNA becomes interacted with another, which is possible. So with this complex say part of the RNA breaks, and maybe a ligase comes and recombines the RNA. In essence your final product is an mRNA that is made from multiple genes. Is this possible?
