RNA polymerase II terminates after a short distance; small oligonucleotides of 4–5 nt are unstable; crystal structures of these RNA/DNA hybrids are unordered. Only longer hybrids have proper base pairing. The short RNA products are degraded rapidly. The suggestion is that this abortive initiation is a form of promoter proofreading.

Cyclic electron transport pathway is catalyzed by the NADH dehydrogenase‐like (NDH) complex in the thylakoid

membrane. This large complex is similar to mitochondrial Complex I,

There are two classes of snoRNPs involved in rRNA processing in nucleolus. 

The box H/ACA snoRNPs are involved in pseudouridylylation, and box C/D snoRNPs function in 2-O-methylations.
