If a repressor protein attaches to the operator, RNA polymerase cannot proceed to transcribe key enzymes needed by the organism. This can be seen in the trp operon in E .coli bacteria.
Shorter mRNA will be found in the ribosomes when comparisons are made
with the mRNA from inside the nucleus.
<h3>Ribosomes</h3>
Ribosomes are organelles which acts as sites for protein synthesis. This is
where the mRNA gets converted into polypeptides which have longer
chains.
Ribosomes have a shorter mRNA in the ribosome which becomes longer in
the nucleus after synthesis of larger polypeptides. this is the reason why
there is a variation in the size of the mRNA found in the ribosome and
nucleus.

Answer:
B) Absence of native grasses
Explanation:
The grasses, which acted as a windbreak and whose roots anchored the soil in place, were overgrazed and/or removed to allow for farming. Once a few years of severe drought affected the area, any wind storm was able to blow the topsoil away, rendering the farm land of the Great Plains virtually unusable in many areas. Ground cover is an essential part of sustainable agriculture.
