九州大学は、極限環境がリボ核酸(RNA)の前生物化学に与える影響を調査し、「アデノシン一リン酸」(AMP)がRNA鎖へ繋がる重合反応を起こす証拠は発見できず、逆に多様な有機化合物へ分解・再編成されることを発見したと発表した。
The ability to evolve is a key characteristic that distinguishes living things from non-living chemical compounds. The construction of an evolvable cell-like system entirely from non-living molecules ...
複数のワクチンが世界で承認され、有効性が報告される一方、安全性に対する懸念も出始めている。独ビオンテックと米ファイザーのワクチン接種が広がったことで、名前を聞く機会の増えているのがワクチンの材料である「RNA」だ。 筆者は医療関連の ...
A 45-nucleotide strand of RNA can now synthesize both its mirror-image complement and a copy of itself, bringing scientists ...
Your DNA is continually damaged by sources both inside and outside your body. One especially severe form of damage called a double-strand break involves the severing of both strands of the DNA double ...
RNA(リボ核酸)で全遺伝情報(ゲノム)を持つウイルス。新型コロナやインフルエンザ、エイズなどのウイルスがある。DNA ...
Researchers identified how the poxvirus protein VITF-3 forms a molecular ring that clamps onto DNA with viral RNA polymerase, bending it by 90 degrees to initiate gene copying.
A strand of RNA just 45 nucleotides long has been discovered to perform two key reactions required for self-replication. The ...
Scientists discover QT45, a self-replicating RNA molecule, offering insights into the origins of life on Earth.
