在细胞的转录过程中，rRNA（核糖体 RNA）和 mRNA（信使 RNA）展现出不同的转录方向，这一现象背后蕴含着深刻的分子机制与生物学意义。 从分子结构 ...

The main types of rRNA include: Small Subunit rRNA: In prokaryotes, the small subunit contains the 16S rRNA, while in eukaryotes, it contains the 18S rRNA. These rRNAs are involved in mRNA binding and ...

Generally, those RNA molecules that do not take the form of mRNA are referred to as noncoding ... the nucleolus is the structure where rRNA processing and ribosomal assembly take place.

Many antibiotics target specific differences in prokaryotic ... Shine-Dalgarno sequence and the 16S rRNA helps position the ribosome correctly on the mRNA, ensuring accurate translation initiation.
