ribonucleic acid / RNA
RNA is often compared to a copy from a reference book, or a template, because it carries the same information as its DNA template but is not used for long-term storage. Each ribonucleotide base ...

RNA Functions
The central dogma of molecular biology suggests that the primary role of RNA is to convert the information stored in DNA into proteins. In reality, there is much more to the RNA story. However ...

New imaging method enables detailed RNA analysis of the whole brain
Researchers at Karolinska Institutet and Karolinska University Hospital have developed a microscopy method that enables detailed three-dimensional (3D) RNA analysis at cellular resolution in whole ...
RNA-targeting CRISPR reveals that hundreds of noncoding RNAs are essential—not 'junk'
Genes contain instructions for making proteins, and a central dogma of biology is that this information flows from DNA to RNA ...

RNA editing is the next frontier in gene therapy—here's what you need to know
What makes it special is the fact the therapy targets RNA, instead of DNA. So, what does that mean, and why should we be excited? Genes are made up of DNA, or deoxyribonucleic acid. Nearly all ...

Statistical analysis supports pervasive RNA subcellular localization and alternative 3' UTR regulation
Analysis of genome-wide spatial transcriptomics data reveals cell-type specific subcellular RNA localization, and a subset of genes show significantly high correlation between spatial patterning and 3 ...
Cellular RNA plays key role in antiviral defense, study finds
Scientists have uncovered a new role for a cell's own RNA in fending off attacks by RNA viruses. Some of the cell's RNA ...

Study reveals RNA's unknown role in DNA damage repair
But Storici's team found that RNA can also help cells repair a severe form of DNA damage called a double-strand break, or DSB. A DSB means both strands of the DNA helix have been severed.

Reproduction, the genome and gene expression - Edexcel
When a gene is to be expressed, the base sequence of DNA is copied or transcribed into mRNA (messenger RNA). This process takes place in the nucleus and occurs in a series of stages. The two ...
