Nucleic acids play a vital role in the process of protein synthesis, which is the core of genetic regulation in cells. This process involves a complex mechanism of DNA, RNA, and ribosomes working in a coordinated manner. DNA (deoxyribonucleic acid) functions as a genetic blueprint that stores information for protein synthesis. Through the process of transcription, DNA is transcribed into messenger RNA (ribonucleic acid) (mRNA) in the cell nucleus. mRNA carries the genetic code to the cytoplasm, where ribosomes act as translation centers. Ribosomes, together with transfer RNA (tRNA), read the codon sequence on mRNA to determine the sequence of amino acids that will be assembled into polypeptides. This process, called translation, involves complex interactions between mRNA, tRNA, and ribosomes to ensure that the resulting protein is in accordance with genetic instructions. In addition, the role of non-coding RNA, such as microRNA and riboswitches, is also important in regulating gene expression post-transcriptionally. A deep understanding of the mechanisms of DNA, RNA, and ribosomes has opened up great opportunities in biotechnology and medicine, such as gene therapy and RNA-based drug development. Thus, the analysis of the role of nucleic acids becomes an important foundation in the exploration of molecular biology and genetics.

This study aims to analyze the relationship between macrozoobenthos Gafrarium pecinatum density and water quality at two water stations determined based on the turbidity of the research location on Sunday, May 26, 2024 in Pengudang waters and Monday, May 27, 2024 in Dompak waters. Field data analysis was carried out in the Marine Biology laboratory of the Faculty of Marine Science and Fisheries UMRAH. This study used a random sampling method with sample collection carried out at two predetermined research stations. The results showed that Gafrarium pecinatum is a macrozoobenthos species found in both research locations, with differences in the number of individuals between stations. Evaluation of water quality showed that most of the chemical and physical parameters were still within the established quality standard limits, but the temperature parameter at station 2 slightly exceeded the quality standard limits. Nonetheless, the water conditions at both sites can still be considered suitable to support the life of marine biota. Further monitoring is required to maintain the sustainability of the coastal ecosystem.
