202221 · Abstract Lead sulfide (PbS) is the main component of galena. The traditional method used to prepare metal lead from galena is disadvantaged by high energy consumption and severe pollution. In this paper, an eco-friendly yet simple process is proposed to prepare high-purity metal lead directly from lead sulfide. According to …

It is vital for cell growth, repair, and reproduction in organisms as it helps with the transmission of genetic information. The replication process follows several steps involving multiple proteins called replication enzymes and RNA, or ribonucleic acid.
