- 生物信息学是一种生物信息学.
- 分子生物学分子生物学
背景情况:
- 短读测序成本下降,导致基于测序的生物研究增加.
- 细菌3'-end测序数据正在迅速积累,但缺乏标准化分析方法.
- 目前的方法通常集中在非编码区域,缺乏系统方法,阻碍了结果的比较.
研究的目的:
- 引入PIPETS (Poisson从Term-Seq数据中识别峰值),这是一个用于分析3'-end测序数据的新R包.
- 为3'-end测序数据分析提供统计学知情和基因注释不可知论的方法.
- 提供一个广泛适用的平台,用于探索和分析跨不同生物体的3端测序数据集.
主要方法:
- 开发了PIPETS,这是一个在Bioconductor上可用的R包.
- 实施了基于统计的,基因注释不可知论的方法.
- 将PIPETS应用于来自不同细菌物种的两个不同的数据集.
主要成果:
- 与现有方法相比,PIPETS在更广泛的基因组环境中发现了显著的3'-end终结信号.

Sanger Sequencing
754.2K
DNA sequencing is a fundamental technique that is routinely used in the biological sciences. This method can be applied to a range of questions at different scales - from the sequencing of a cloned DNA fragment or the study of a mutation in a gene up to whole-genome sequencing. However, despite the widespread use of sequencing today, it was not until 1977 that Fredrick Sanger and his collaborators developed the chain-termination method to decode DNA sequences. It relies on the separation of a...

Next-generation Sequencing
88.7K
The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.
