The task of transcribing nuclear genes is shared between three RNA polymerases in eukaryotes: RNA polymerase (pol) I synthesises the large rRNA, pol II synthesises mRNA …
New types of small RNAs distinct from microRNAs (miRNAs) are progressively being discovered in various organisms. In order to discover such novel small RNAs, a library of 17 …
Gene transcription in the cell nucleus is a complex and highly regulated process. Transcription in eukaryotes requires three distinct RNA polymerases, each of which employs …
RNA polymerase is a ratchet machine that oscillates between productive and backtracked states at numerous DNA positions. Since its first description 15 years ago, backtracking—the …

▪ Abstract Ubiquitous in eukaryotic cells, the La protein associates with the 3′ termini of many newly synthesized small RNAs. RNAs bound by the La protein include all nascent …
The small ribonucleoproteins recognized by anti-La sera consist mainly of RNA polymerase Ill products complexed with an antigenic cellular protein of 50 kd. A biochemical procedure …
