Protein synthesis is the cellular process through which genetic information is translated into functional proteins, essential for cellular structure and function. It involves two main stages: transcription, where DNA is converted into mRNA, and translation, where mRNA is decoded by ribosomes to assemble amino acids into polypeptide chains.
Concept
Transcription elongation is a phase in the process of transcription where RNA polymerase moves along the DNA template, synthesizing RNA by adding nucleotides to the growing RNA strand. This stage is crucial for accurate gene expression and is regulated by various factors to ensure proper mRNA synthesis and processing.
