The Bucyrus RH400, now owned by Caterpillar, is said to hold the title of the world's biggest hydraulic excavator. This monster is a front shovel excavator and weighs in at around 980 tonnes. This mine chewer has an undercarriage width of 8.6 meters and crawler length of 10.98 meters.

avanturin [10]

Answer:

The correct answer is option E. "nucleotides can only be added to an available 3'-OH group on the transcript terminus".

Explanation:

RNA synthesis is catalyzed by an enzyme called RNA polymerase. RNA polymerase always catalyze the synthesis of new RNA from 5' to 3' because nucleotides can only be added to an available 3'-OH group on the transcript terminus. This has been confirmed in labeling experiments with γ-32P substrates which establish the presence of a triphosphate moiety in transcripts with either pppG or pppA.
