Undoing a hairpin doubles gene activity
Male fruit flies have one X chromosome per cell, females have two. So genes on the male X must work twice as hard to produce the same amount of protein as its female counterparts. An LMU team has found a ...
Hairpin turn: Micro-RNA plays role in wood formation
For more than a decade, scientists have suspected that hairpin-shaped chains of micro-RNA regulate wood formation inside plant cells. Now, scientists at NC State University have found the first example and mapped out key ...
Molecular twist helps regulate the cellular message to make histone proteins
Histone proteins are the proteins that package DNA into chromosomes. Every time the cell replicates its DNA it must make large amounts of newly made histones to organize DNA within the nucleus.
A pathway to bypass DNA lesions in the replication process is experimentally shown
DNA lesions are really common —about one million individual molecular lesions per cell per day— because its long strands usually have one missing base or are damaged. These lesions can stall the DNA replication ...
Molecular motors of nucleic acid: Researchers work to improve screening of helicase-targeting drugs
European scientists investigated the dynamic unfolding of DNA during replication by generating a tool that could subsequently be applied to screen helicase-targeting drugs for infection and oncologic applications.
Botany student proves 'New England Banksia' a distinct species
The New England Banksia is largely restricted to the eastern edge of the New England Tableland, and is common in places along Waterfall Way. Ms Stimpson's research has raised this flowering plant, until now cl ...
New historic finds help paint picture of lime workers' lives
(PhysOrg.com) -- The hairpin may have held a woman's hair back long ago, but now it holds a wealth of information.
