RNA synthesis and processing involves several key steps:
- Synthesis: RNA synthesis, or transcription, occurs when RNA polymerase binds to the DNA template at a promoter site, initiating the formation of a new RNA strand. This process includes initiation, elongation, and termination2.
- Processing: Newly synthesized mRNA, known as precursor mRNA, undergoes significant modifications, including the addition of a 5' cap and a poly-A tail, as well as splicing to remove introns. These changes are essential for the maturation of mRNA before it can be translated into proteins4.
- Types of RNA: In addition to mRNA, RNA synthesis also produces ribosomal RNA (rRNA) and transfer RNA (tRNA), which play crucial roles in protein synthesis and cellular functions2.
This comprehensive overview highlights the essential processes involved in RNA synthesis and processing.

Binding of RNA polymerase enzyme to the template at a promoter site on DNA. 2. Initiation of new strand. 3. Elongation. 4. Termination and release. Length of mRNA chain depends upon the length of polypeptide chain it codes for.www.biologydiscussion.com/rna/synthesis-of-rna-tr…he synthesis of RNA, is called transcription. Transcription produces messenger RNA (mRNA), which is translated into sequences of amino acids (proteins), and ribosomal RNA (rRNA), transfer RNA (tRNA), and additional RNA molecules that perform specialized structural, catalytic, an
learning.medicine.wsu.edu/wp-content/uploads/site…Newly synthesized mRNA is called primary transcription or precursor mRNA. It is quite different from the mRNA that takes part in protein synthesis. Large-scale changes take place in precursor mRNA. These changes are called processing of mRNA. Both 5′-end 3′-end of mRNA are modified.www.biologydiscussion.com/rna/rna-processing-eu…In eukaryotes, synthesis, cutting, and assembly of rRNA into ribosomes takes place in the nucleolus region of the nucleus, but these activities occur in the cytoplasm of prokaryotes. Within the nucleolus region, ribosome assembly requires the activity of numerous snoRNAs.wou.edu/chemistry/courses/online-chemistry-textbo…- People also ask

DNA Transcription (RNA Synthesis)- Article, Diagrams and Video
- In prokaryotic cells, the entire mechanism of transcription is summarized in three stages: Initiation, Elongation, and Termination.
- At the end of the termination in prokaryotes, the mRNA formed is ready for translation.
- Unlike in eukaryotes, after termination, an immature mRNA is formed, and therefore, more processes are needed to form a mature mRNA which is then translated into proteins.
