Transcription elongation checkpoint discovered

Northwestern Medicine scientists have identified a critical checkpoint in transcription elongation, the process of synthesizing RNA from a DNA template, according to findings published in Molecular Cell.

Examining mRNA transcription difficulties

The corona pandemic has ensured that the term "mRNA" is now also known to a large public beyond laboratories and lecture halls. However, the molecule is much more than an important component of a successful vaccine against ...

How cells 'read' artificial ingredients tossed into genetic recipe

If the genome is the recipe of life, base pairs are the individual ingredients listed. These chemical structures form DNA, and every living organism on Earth has just four. The specific arrangements of these four base pairs—A, ...

New discovery shows human cells can write RNA sequences into DNA

Cells contain machinery that duplicates DNA into a new set that goes into a newly formed cell. That same class of machines, called polymerases, also build RNA messages, which are like notes copied from the central DNA repository ...

A protein with a dual role: Both repair and mutation

Using a specialized protein, all bacteria are capable of rapidly and effectively repairing damage to their DNA from UV. However, this mutation frequency decline (Mfd) protein plays another role and causes mutations. A team1 ...

Lab one step closer to understanding how life started on Earth

How did life begin on Earth and could it exist elsewhere? Researchers at Simon Fraser University have isolated a genetic clue—an enzyme known as an RNA polymerase—that provides new insights about the origins of life. ...
