Known to be fine regulators of gene expression, microRNAs are small molecules that remain particularly stable in biofluids—blood, urine, etc. In humans, these molecules have revealed great potential as prognostic or diagnostic ...

After a gene is transcribed into RNA, modifications can occur to the subunits or "bases" that make up the RNA molecule, which can affect its structure and function. The study of these changes is known as "epitranscriptomics." ...

MicroRNAs are short RNA sequences that maintain a tight control on which genes are expressed and when. They do this by regulating which messenger RNA (mRNA) transcripts—the single-stranded templates for proteins—are actually ...

Only 1.1% of the nearly 3 billion molecules that make up our genome actually provide genetic instructions. When scientists first worked out what the sequence of letters in our genome was, they originally estimated that as ...
