The free end of the second RNA is uncapped and thus can be distinguished from genuine transcripts. This new RNA is recognized by an RNase called, in yeast, _ and in humans_ that is loaded onto the end of the RNA by another protein that binds the CTD of RNA polymerase.

Several transport steps are involved in the movement of photosynthate from the mesophyll chloroplasts to the sieve elements of mature leaves; The following steps are invoved with sucrose transportation is given;

a) During the day, triose phosphate is transported from the chloroplast to the cytosol, where it is converted to sucrose.

b) During the night, carbon from stored starch exits the cytosol primarily in the form of maltose and is converted to sucrose

c) Sucrose moves from the mesophyll cells to the sieve elements in the smallest veins of the leaf. This is called short-distance transport pathway

d) With respect to unloading, sucrose and other solutes are translocated away from the source through the vascular system to the sink is referred to as long-distance transport

Which of the following combination is correct?
