A quasi-category is a concept from the field of category theory, specifically in homotopy theory. It is used to formalize the notion of "weak n-categories" where we want to study spaces that behave like categories, but where the laws of composition and associativity are only satisfied up to higher homotopies. Quasi-categories are defined in a more relaxed way compared to ordinary categories.

In genetics, "coverage" refers to the extent and depth of sequencing of a particular region of DNA in a genomic analysis. Coverage can be described in two primary ways: 1. **Read Coverage (or Depth of Coverage)**: This metric indicates how many times a particular nucleotide in the genome has been sequenced during a sequencing experiment. For example, if a specific region of DNA has been sequenced ten times, it is said to have a coverage of 10x.
DNA ligase is an essential enzyme in molecular biology that plays a critical role in DNA replication and repair. Its primary function is to join together two DNA strands by forming phosphodiester bonds between the sugar and phosphate groups of adjacent nucleotides. This process is crucial for the following reasons: 1. **DNA Replication**: During DNA replication, the enzyme aids in the joining of Okazaki fragments on the lagging strand, creating a continuous DNA strand.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
