Astrain of yeast translates mrna into protein with a high level of inaccuracy. individual molecules of a particular protein isolated from this yeast have the following variations in the first 11 amino acids compared with the sequence of the same protein isolated from normal yeast cells. assuming that this abnormality results from a single mutation in the cell, what do you think is the most likely cause of this variation in protein sequence? why? normal sequence met thr ala ile val ser asn thr gln ile lys variants asn thr gln ile lys met thr ala gly val ser asn thr gln ile lys asn thr gln ile lys asn thr gln ala lys asn thr gln gly lys ser asn thr gln val lys met thr ala ala val ser met thr ala val val met thr ala ile val met thr ala ile val ser ser ser met thr ala ile val

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.
