Question

A molecule that can be used as a molecular clock has a neutral mutation rate of one mutation per 10 million years. How many years ago did two species share a common ancestor if the molecules found in these two species differ by a total of six mutations?

6 million years

30 million years

10 million years

60 million years ---- not the answer

Answer 1

Answer 2

it's 20.........

Answer 3

but not in option so i will go with 30 i guess but not sure. but i am quite sure it should be 60 other wise ( number of mutations by the rate at which mutations occur to get the number of years since the species diverged.)

Answer 4

can you help me with one more
What makes mitochondrial DNA useful as a molecular clock?

Answer 5

It is only found in select organisms, making it easier to compare relationships between species that have it.

A large portion of the DNA ring is not vital to structure or function, allowing it to accumulate neutral mutations.

Its rate of mutation increases over time as organisms continue to evolve and differentiate from each other.

A slow mutation rate makes it useful for determining evolutionary relationships between ancient species.

A slow mutation rate makes it useful for determining evolutionary relationships between ancient species....

Answer 8

its not, none of them
maybe first is 30
and secnd i dont know

Answer 9

yes it was 30

Answer 10

great genius!!! @laurisve
