QUESTION 1
Which of the following genetic techniques does NOT use labelled DNA probes?
Molecular clocks B. TAKE ADVANTAGE OF THE FACT THAT ALL MUTATIONS HAPPEN AT A STEADY RATE.
The molecular clock is a technique used involving the mutation rate of biomolecules to deduce when in prehistoric times have two or more lifeforms diverged.
If the mutation is beneficial, the mutated organism survives to reproduce, and the mutation gets passed on to its offspring. In this way, natural selection guides the evolutionary process to incorporate only the good mutations into the species, and expunge the bad mutations.
