5. A gene has a base sequence of GTC. Due to a mutation, the base sequence changes to GTG. Answer the following questions using the codon table below.
e) Is this a silent mutation or a missense mutation?
f) What is the difference between a missense mutation and a silent mutation?
g) If the strand of DNA with the sequence GTA mutated to GTG, would this be a silent or missense mutation?
h) If the strand of DNA with the sequence TTA mutated to TTG, would this be a silent or missense mutation?
i) If the strand of DNA with the sequence TGA mutated to GGA, would this be a silent mutation or a missense mutation?

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.

a. an idea which cannot be disproven!
