In reality, there is much more to the RNA story ... Inside the eukaryotic nucleus, the nucleolus is the structure where rRNA processing and ribosomal assembly take place. Molecules called small ...

which binds to specific promoter regions on the DNA and initiates the synthesis of the complementary RNA strand. The resulting primary transcript, known as pre-mRNA in eukaryotes, undergoes several ...

Immediately after a gene in a eukaryotic cell is transcribed, the new RNA molecule undergoes several modifications known as RNA processing. These modifications alter both ends of the primary RNA ...

The 30S subunit contains a 16S ribosomal RNA (rRNA) molecule, while the 50S subunit harbors 23S and 5S rRNA molecules. In contrast, eukaryotic cells have 80S ribosomes, which are larger and more ...

In most eukaryotic cells, two types of spliceosome ... information—called introns—from the precursors of messenger RNA (pre-mRNA), the molecule responsible for transferring genetic information ...
