This article is written in British English, which has its own spelling conventions (colour, travelled, centre, defence, artefact, analyse) and some terms that are used in it may be different or absent from other varieties of English. According to the relevant style guide, this should not be changed without broad consensus.

Compressed Representation[edit]

Does anyone have information about the recent news that DNA is in a compressed form and that the "junk" is actually part of the decompression mechanics? (kind of like a zip file) That would be an important addition to this article. Actually, it makes sense that the genome would be in the most compressed state to make reproduction efficient.

Under "Base Pairing"

add: (or "Watson–Crick–Franklin") to "Watson-Crick base pair", to match current terminology in DNA science. Vecchionis (talk) 18:17, 16 November 2022 (UTC)[reply]

Not done: please provide reliable sources that support the change you want to be made. Actualcpscm (talk) 23:09, 16 November 2022 (UTC)[reply]

Reviewers laud authors for updating the terminology of the base pair to "Watson-Crick-Franklin" in the ACS journal "Biochemistry".

Editing.[edit]

Hey. Can I edit this page. Because I want to make it simpler. 129.126.35.127 (talk) 00:54, 16 May 2023 (UTC)[reply]

"first sequencing of DNA from animal remains": seems to be wrong as stated.[edit]

Section "Evolution" says

In February 2021, scientists reported, for the first time, the sequencing of DNA from animal remains, a mammoth in this instance over a million years old, the oldest DNA sequenced to date.

Haven't scientists have been sequencing DNA from animal remains for quite a while before 2021?

Should this say something like "scientists reported, for the first time, the sequencing of DNA from subfossil animal remains" or "the sequencing of DNA from the remains of an extinct animal" or something along those lines?

- 189.60.49.251 (talk) 04:57, 8 November 2023 (UTC)[reply]

Presumably this should refer to the fact that DNA has been recovered from ancient organisms on a timescale where evolutionary change can be observed. At present it reads like random clickbait for the referenced studies. Would suggest changing:

" In February 2021, scientists reported, for the first time, the sequencing of DNA from animal remains, a mammoth in this instance over a million years old, the oldest DNA sequenced to date. "

to

" Ancient DNA has been recovered from ancient organisms at a timescale where genome evolution can be directly observed, including from extinct organisms up to millions of years old, such as the woolly mammoth^[1]. "

There are also issues with first paragraph of the section (which relies on very outdated references for DNA degradation) but will see if any action happens with the above before taking more time to suggest re-drafts for this. 130.226.236.6 (talk) 17:47, 28 May 2024 (UTC)[reply]

Book "How Life Works" (2023) worth considering?[edit]

A review by scientist Denis Noble of a new book entitled "How Life Works: A User’s Guide to the New Biology" (2023) by Philip Ball (editor of the journal Nature) may be worth considering?^[2] - iac - Stay Safe and Healthy !! - Drbogdan (talk) 04:40, 6 February 2024 (UTC)[reply]
