a geneticist was able to reconstruct a sequence of mitochondrial dna of a prehistoric insect that was encased in amber. a segment of this dna in species a was found to have the sequence aggtcctaag. this segment of dna has had one mutation every 100 million years. species b has the dna sequence aggtccgaag. how many years ago did these species diverge from a common ancestor? 1,000,000 years 200,000 years 50,000,000 years 60,000 years

Sagot :

The number of years ago at which specie A and B diverge from a common ancestor is 1,000,000 years. Option A is correct.

What is mitochondrial?

The mitochondrial is the structure in the cells whose main function is to convert the energy from the food in such a form that the cell can use.

A geneticist was able to reconstruct a sequence of mitochondrial dna of a prehistoric insect that was encased in amber.

A segment of this dna in species A was found to have the sequence AGGTCCTAAG. Species B has the dna sequence AGGTCCGAAG. Thus, the sequence is,

  • Species A- AGGTCCTAAG.
  • Species B- AGGTCCGAAG.

This segment of dna has had one mutation every 100 million years. The DNA sequence has only one mutation. For this, 100 million year is required.

Thus, the number of years ago at which specie A and B diverge from a common ancestor is 1,000,000 years. Option A is correct.
