biological replicateFeb 12, 2021 — Learn the difference between technical and biological replicates in experimental design and statistical power. Find out how to apply biological replicates .• Biological replicates are parallel measurements of biologically distinct samples that capture random biological variation, which may itself be a subject of study or a .Learn the definitions, purposes, and examples of biological and technical replicates in biomedical research. Explore the challenges and best practices of replication, such as .Apr 7, 2016 — Broadly speaking, biological replicates are biologically distinct samples (e.g. the same type of organism treated or grown in the same conditions), which show .Apr 7, 2015 — This Focus tackles the issue of technical versus biological replicates, what constitutes appropriate biological replicates, and appropriate statistical analysis for data with small sample sizes. Three biological entities or units have been proposed to better define where replication should occur 4,5.The first is the scientific or biological unit (such as a person, animal or cell), which . Biological replicates: a test performed on biologically distinct samples representing an identical time point or treatment dose; i.e., if there are triplicate non-treated samples, a biological replicate would be testing sample #1, . Broadly speaking, biological replicates are biologically distinct samples (e.g. the same type of organism treated or grown in the same conditions), which show biological variation; technical replicates are repeated measurements of a sample, which show variation of the measuring equipment and protocols. Use of biological replicates is much more common in RNA-seq studies, especially when multiple congenic individuals (e.g., mice) are available. Biological replicates can formally be used to . Generally, biological replicates are defined as measurements of biologically distinct samples that show biological variation . In contrast, technical replicates are repeated measurements of the same sample that show independent measures of the noise associated with the equipment and the protocols. Biological replicates are of paramount importance as they capture random biological variation and thus, reduce the possibility of detecting a false positive hit. With the advent of stem cell biology and routine differentiation of human embryonic stem cells (hESCs) or human induced pluripotent stem cells (hiPSCs) into a multitude of desired . Biologists determine experimental effects by perturbing biological entities or units. When done appropriately, independent replication of the entity–intervention pair contributes to the sample size (N) and forms the basis of statistical inference. If the wrong entity–intervention pair is chosen, an experiment cannot address the question of .生物重复和技术重复分别是什么？在一个实验中应该如何安排生物重复和技术重复？ 重复是实验设计的重要原则之一，实验重复无论对于实验结果的可重复性，还是对于最终实验结论的可靠性，都起着起决定性的作用。. 实验重复还可以进一步细分为生物重复(biological replicates)和技术重复(technical .
biological replicateA biological replicate is an individual of the same group in an experiment. For example, we want to test of drought on Pinus sylvestris. We need two groups of samples, Control and Drought, and .In molecular biology, [1] [2] [3] DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. [4] DNA replication occurs in all living organisms acting as the most essential part of biological inheritance.Biological replicates take into account variation within a defined group. For example, when examining the effect of drug treatment on the gene expression level of a mouse mRNA target, multiple mice are needed as samples to estimate the variation of that target in the population. In this example, a biological group might consist of a group of .
