Identify the types of mutation depicted ggc to gga

When there is a mutation in the DNA nucleotide sequence where GGC passes into GGA, the mutation is a point mutation of the silent type.

Explanation:

A point mutation of DNA, where the cytosine nucleotide is changed to adenine, GGC to GGA, the resulting triplet mRNA is CCU, instead of GCC.

Codons CCG and CCU encode the same amino acid, which is proline (Pro), so despite the existence of a mutation, the protein that is synthesized will not have alterations in its number or sequence of amino acids.

Silent mutations are characterized by changes in a nucleotide in the DNA base sequence that do not affect changes in the coding protein, as happens in the change of GGC to GGA.

plate tectonics and volcanic euptions

over time, plate tectonic processes cause continents to move to different positions on the globe.

for example, britain was near to the equator 300 million years ago, and therefore was hotter than it is today. for further details look at our climate through time poster or online map.

the movement of the plates also causes volcanoes and mountains to form and these too can contribute to a change in climate.

mountain ranges formed by plate tectonics. large mountain chains can influence the circulation of air around the globe, and consequently influence the climate.   warm air might be deflected somewhere cooler by the mountains.
