Credit: Kateryna Kon/Science Photo Library/ What is DNA, and how does it work? You don't need a degree in genetics to understand. Here, we'll give an overview of DNA and answer questions ...

The sequence of base pairs in DNA determines the genetic code, which is read in triplets to specify the amino acid sequence of proteins. The complementary nature of base pairing allows for the ...

Accessing DNA wrapped into basic units of packaging, called nucleosomes, depends on the underlying sequence of DNA building blocks, or base pairs. Like Christmas presents, some nucleosomes are ...

Ultraconserved elements are DNA sequences, hundreds of base pairs long, that are 100-percent identical in mice, rats and humans. Their perfect conservation for over 80 million years was thought ...

Sequencing DNA is very, very simple: there's a molecule, you look at it, you write down what you find. You'd think it would be easy -- and it is.

Here we describe 55.8 million base pairs of highly accurate finished sequence representing 99.9% of the euchromatin portion of the chromosome. Manual curation of gene loci reveals 1,461 protein ...

In 1953, scientists proposed that DNA is structured as a double helix, with the chemical bases—adenine (A), cytosine (C), guanine (G), and thymine (T)—stacked up in pairs between two ...

The technique uses a long strand of DNA with a set sequence—the template—and a bunch of shorter, premade DNA molecules that can base pair with specific spots on the template—the bricks.

Building off the powerful gene-editing technology known as CRISPR, researchers have created a new tool that can target and change a single letter in a sequence of DNA.

He’s now shown, in a Nature paper published Wednesday, that cells can not only hold on to the new base pairs, but they can use custom RNA sequences to transcribe codons with these new base pairs into ...

DNA data from Africans reveals sequences that we’d missed ... Sherman and her colleagues looked for sequences more than 1,000 base pairs long that didn't match the reference and found a lot of ...
