abstract：:The roles of 2'-OH groups in the binding of mRNA to human ribosomes were studied using site-directed cross-linking. We found that both mRNA and mDNA analogues bearing a cross-linker can modify ribosomal proteins (rps) S3e and S2e at the mRNA entry site independently on tRNA presence, but only mRNA analogues were capab...
