So-called Alu elements are repetitive DNA sequences that can generate bits of RNA, a molecular cousin of DNA, that can convert back to DNA and then insert themselves randomly into the genome. These ...

However, when the TBXT gene produces RNA, the repetitive nature of Alu sequences causes them to bind together, resulting in the removal of an entire exon during RNA splicing. Experimentation ...

L1, Alu and SVA elements also substantially shape human evolution at the RNA level by modulating the expression of nearby genes, RNA editing and epigenetic regulation. Their ability to move within ...

One of the more famous of these devices is the 74181, a cascadable 4-bit arithmetic logic unit, or ALU. An ALU is the heart of a microprocessor, performing its operations. The 74181 appeared in ...

Wave Life Sciences said today its alpha-1 antitrypsin deficiency (AATD) candidate WVE-006 succeeded in the first-ever clinical demonstration of RNA editing in humans by achieving positive proof-of ...

记者10月10日从中山大学获悉，中山大学医学院施莽教授团队与阿里云李兆融团队在《细胞》杂志（Cell）发表的论文报告了全球范围的180个超群、16万余种的RNA病毒发现，大幅扩展了全球RNA病毒的 ...

Overview of RNA repair – There is an emerging appreciation of the existence of “RNA repair” pathways that rely on RNA ligases to maintain or manipulate RNA structure in response to purposeful RNA ...

微小RNA（micro RNA）是一种很小的RNA分子。em，长度约为22nt（21-23nt）。micro RNA有几个特点： ①没有开放阅读框， 是非编码RNA，顾名思义就是 ...

Researchers say they have successfully completed a trial of a personalised cancer vaccine that uses the same messenger-RNA technology as Covid jabs. The experimental vaccine, made by Moderna and ...

The remaining positions are occupied by carbon atoms, forming the backbone of important nucleobases in DNA and RNA. (Image: Public Domain) Types of Pyrimidines in Nucleic Acids There are three types ...

上世纪90年代，美国科学家维克托·安布罗斯和加里·鲁夫坎找到了“生命指南”的关键——微小核糖核酸（微小RNA）及其在转录后基因调控中的作用 ...

Several antiviral and anticancer drugs target the incorporation of adenine into DNA or RNA. For example, some nucleoside analog drugs, such as vidarabine and fludarabine, mimic adenine and interfere ...
