Plsssss ooo I don't really know how this is done

<h2>Summary</h2>
<p>The currently accepted <a href="https://app.ulearngo.com/tutorials/history-of-life-ii/ring-of-life-models">model</a> of the double-helix structure of <a href="https://app.ulearngo.com/tutorials/introducing-genetics/dna">DNA</a> was proposed by Watson and Crick. Some of the salient features are that the two strands that make up the double helix are complementary and anti-parallel in nature. Deoxyribose sugars and phosphates form the backbone of the structure, and the nitrogenous bases are stacked inside. The diameter of the double helix, 2 nm, is uniform throughout. A purine always pairs with a pyrimidine; A pairs with T, and G pairs with C. One turn of the helix has ten base pairs.</p>
<p>During cell division, each daughter cell receives a copy of the DNA by a process known as DNA replication. Prokaryotes are much simpler than <a data-lesson="characteristics-of-eukaryotes" data-subject="biology" data-tutorial="protists" href="https://app.ulearngo.com/biology/protists/characteristics-of-eukaryotes">eukaryotes</a> in many of their features. Most <a data-lesson="needs-of-prokaryotes" data-subject="biology" data-tutorial="prokaryotes-bacteria-archaea" href="https://app.ulearngo.com/biology/prokaryotes-bacteria-archaea/needs-of-prokaryotes">prokaryotes</a> contain a single, circular chromosome. In general, eukaryotic <a data-lesson="chromosomes" data-subject="biology" data-tutorial="cell-biology" href="https://app.ulearngo.com/biology/cell-biology/chromosomes">chromosomes</a> contain a linear DNA molecule packaged into nucleosomes, and have two distinct regions that can be distinguished by staining, reflecting different states of packaging and compaction.</p>

Summarizing DNA Structure and Sequencing

Biology studies life and living organisms. Biology can be divided into different sections that cover the morphology, physiology, anatomy, behavior, and so on of living organisms.

Biology

Discover the history and structure of DNA, learn about DNA sequencing techniques, and explore the basics of DNA replication and repair.
