A geneticist outlines the protocol for analyzing a prehistoric specimen. Arrange the following steps of the laboratory procedure in the correct chronological order, ensuring the sequence maintains parallel structure throughout the list.
- 1to extract the ancient DNA from the fossilized bone,
- 2to amplify the recovered DNA fragments using polymerase chain reaction,
- 3and to sequence the resulting genetic data for evolutionary comparisons.
Cevap
The correct sequence of steps in the laboratory procedure is first extracting the DNA, then amplifying the fragments, and finally sequencing the genetic data.
The correct order follows the chronological progression of a scientific workflow: first, isolating the DNA ('to extract'); second, multiplying the sample ('to amplify'); and third, analyzing the genetic sequence ('to sequence'). Each action is phrased using an infinitive, satisfying the requirements of parallel structure.

Anahtar Kavram
Parallel structure requires that all items in a list or sequential process use the same grammatical form (such as infinitives, gerunds, or clauses) to maintain clarity and rhythm.
