Two molecular control factors play a decisive role in what is known as splicing, the cutting and assembly of mature messenger ...

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, in ...

The resulting primary transcript, known as pre-mRNA in eukaryotes, undergoes several processing steps before becoming a mature mRNA molecule: After processing, the mature mRNA is transported from the ...

A different nucleic acid molecule, known as messenger RNA, makes a copy of the gene sequence and carries it outside the nucleus. The message encoded in the messenger RNA is read by structures ...

Messenger RNA carries genetic information from DNA in the highly protected nucleus out to the rest of the cell, where structures called ribosomes can build proteins according to the DNA blueprint.

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 ...

In addition to exporting materials out of the nucleus, the protein, called Exportin-1 (also called Xpo1 or Crm1), seems to play a role in promoting gene transcription, the process that creates RNA ...

This core performs non-radioactive, RNA in situ hybridization (ISH) on tissue sections ... Co-transmitting neurons in the lateral septal nucleus exhibit features of neurotransmitter switching. IBRO ...

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