The genetic blueprint for all life forms is in the form of nucleic acid, the most common being deoxyribonucleic acid (DNA). This chemical carries within its structure the ability to encode all the ...

Life on Earth reached a decisive turning point about 2.6 billion years ago. An international team of researchers has just ...

Comparisons of human chromosome 19 and mouse DNA sequences confirm extensive coding and non-coding conservation with 4,586 discrete fragments showing conservation (> 70% identity with a score of ...

It was once thought that non-coding regions were effectively “junk” DNA. 1 Using very different technologies ... but the glut of new research in the field shows that the complete sequence was only a ...

DNA (100 ng) was used in PCR reactions (25 μl ... 1 (Na-DeNe) has now been sequenced. He carries sequence G.

Non-coding DNA variants contribute to acute lymphoblastic ... containing the variant or reverted the mutation to the original sequence, they could alter the cells' sensitivity to the ...

The rest — 98.5 percent of DNA sequences — is so-called “junk DNA” that scientists long thought useless. The non-protein-coding stretches looked like gibberish sentences in a book draft — useless, ...

When a gene is transcribed from DNA, it often contains many parts that must be removed, or spliced out of the gene sequence. Once the cellular machinery ... This work revealed that such mutations in ...

Much of the "junk" DNA in Drosophila shows signs of either negative or positive selection, according to a study in this week's Nature. An analysis by Peter Andolfatto of the University of California, ...

In future, a more ambitious version of this project could attempt to understand how non-protein coding DNA sequences regulate genes by building chunks of synthetic DNA from scratch and ...

Sorting through non-coding DNA to find the root of chemotherapy resistance ... the variant or reverted the mutation to the original sequence, they could alter the cells' sensitivity to the ...
