Why are molecular clocks important in the construction of cladograms? they compare the frequency of reproduction to determine wh
ich traits evolved through mutations. they compare the genes inherited by a species to determine descendants. they compare the number of mutations to determine how long ago species separated and evolved?
They compare the number of mutations to determine how long ago species separated and evolved.
Explanation:
Molecular clocks compares the total number of different nucleotides present in genome of two organisms to estimate the time of their divergence from each other. The average rate at which the specific gene evolves tells about the dates of evolutionary branch points. In this way, the molecular clocks compare the number of mutations to determine how long ago species separated and evolved.
In the presence of oxygen, pyruvate is transformed into an acetyl group attached to a carrier molecule of coenzyme A. The resulting acetyl CoA can enter several pathways, but most often, the acetyl group is delivered to the citric acid cycle for further catabolism.
