An aquatic plant breathes through pores in the atmosphere, creating a bacterial loop cycle. Harmful toxins and pathogens invade the foreign substrate and recessive genes. The purpose of this study is gene editing and gene expression containing information to produce proteins and fight back pathogens. The Methodology of this study is the biosphere of RNA involved in the transcription and translation of DNA to detect several diseases. It is a narrative review of DNA biosynthesis in identifying the mutations for genes, chromosomes, or proteins. Genetic alterations in cancer development have urged many researchers to continue their expedition to find prevention strategies and treatments that are curable for the disease. Thus, gene therapies include gene augmentation, gene slicing, gene suicide, and gene editing by treating certain diseases. The momentum of replacing a damaged gene with a healthy gene using gene therapy in treating a wide range of diseases is quite impressive. An inborn child will have a healthy gene by inheriting it from the parent to the infant for further development. Circular RNAs are meant for protein synthesis. The nutrients are the building blocks of amino acids. The regrowth of new tissues is used to rejuvenate organ transplants. It is highly apprehensive for microbial cells to produce on their own. Not all bacteria are good, but the ones that fight off pathogens in the circular loops of plasmids. The DNA of bacterial cells is composed of chromosomal traits of inheritance in providing nutritious meals and becoming an antibody.

Effect of the use of ovaprim® on the spawning of kissing gourami (Helostoma temminckii) at UPR Doa Mandeh, Ogan Ilir

2025-02-03T10:09:37+00:00

The kissing gourami (Helostoma temminckii) is a freshwater species increasingly cultivated in controlled aquaculture systems. However, its production is hindered by the limited availability of broodstock and fry, which still heavily depend on natural catches that fluctuate seasonally. To address this challenge, controlled environment aquaculture offers a sustainable solution to boost the kissing gourami population. One effective method is semi-natural spawning through gonadotropin hormone induction using Ovaprim^®, which promotes year-round reproductive readiness in broodstock. This study aims to apply and evaluate the semi-natural spawning technique of kissing gourami using Ovaprim^® at UPR Doa Mandeh, Ogan Ilir. Conducted between August and September 2024, the research compared two treatments: natural spawning (P0) and semi-natural spawning (P1). The findings demonstrated promising results, with a fecundity of 9,619 eggs, a fertilization rate of 90.4%, a hatching rate of 94%, and a survival rate of 95%. Water quality parameters remained within optimal ranges, with broodstock pond temperatures between 30–30.6°C and pH levels of 7.27–7.53, while the rearing aquarium maintained a temperature of 31°C and a pH of 7.62–7.66. These results highlight the potential of semi-natural spawning using Ovaprim^® as a viable approach for enhancing kissing gourami reproduction, reducing dependency on wild populations, and supporting sustainable aquaculture practices.

Critical thinking is a crucial 21st-century skill that enables students to analyze information, evaluate arguments, and make logical decisions. However, assessments in Biology education often focus more on factual knowledge rather than higher-order thinking skills. This research aimed to develop an assessment instrument for measuring students' critical thinking skills in diffusion and osmosis. This study used the ADDIE model, which consists of five stages: analysis, design, development, implementation, and evaluation. The research was conducted with 46 students from the XI MIPA class at MA Nurul Huda Munjul. The assessment instrument consists of multiple-choice questions designed to evaluate six components of critical thinking: interpretation, analysis, evaluation, inference, explanation, and self-regulation. Validation results indicate that 20 out of 24 test items are valid, while four require revision or replacement. Reliability testing using the split-half method shows a coefficient of 0.672, which falls into the moderate reliability category and is still acceptable for educational assessment purposes. The developed instrument provides teachers with a tool to evaluate students’ critical thinking skills better and tailor their teaching strategies accordingly. This study contributes to improving Biology education by promoting a more contextual and problem-solving-based approach to assessment.
