Amplicon sequencing of Tara Oceans DNA samples corresponding to size fraction...

Seawater was filtered from different depths to retain small and large cell sizes (Protists and bacteria Organisms). The DNA was extracted and amplified by PCR.研究人员对不同深度的海水样本进行过滤处理，以截留不同粒径的细胞，涵盖原生生物（Protists）与细菌类生物。随后提取样本中的DNA，并通过聚合酶链式反应（Polymerase Chain Reaction，PCR）进行扩增。
