messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). Although some RNA molecules are passive copies of DNA, many play crucial, active roles in the cell. For example, some RNA ...

Only recently has the ribosome—one of the oldest molecular machines in evolutionary terms—been recognized as an active ...

RNA polymerase controls the process of transcription, during which the information stored in a molecule of DNA is copied into a new molecule of messenger RNA. RNA polymerases have been found in ...

Genes are expressed when messenger RNA is made from DNA ... from the flawed mathematical assumptions of older tools. For example, different cell types have different total levels of RNA expression.

Twist Bioscience, for example, offers a rapid library preparation kit ... The kit protocol includes an optional depletion step for removing ribosomal and globin RNA, leaving only messenger RNA. It ...
