Which of the following statements about the removal of introns is correct? spacer dna is removed from primary transcripts at the same time as introns. if introns are not removed by snrnps, catalytic ribosomes are also able to recognize the coding sequence and can cleave out the introns. introns are removed in the nucleus prior to the export of the mrna into the cytoplasm. although the number of introns to be removed can vary from gene to gene, the size of the excised introns is approximately equal from gene to gene. since snrnps cleave in the interior of the primary transcripts to remove introns, this is an example of exonuclease activity.

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
