Protein synthesis is a fundamental process by which cells generate new proteins. It occurs in two main stages: transcription and translation.
Transcription is the first step, where the DNA template is used to create mRNA in the nucleus. This mRNA then carries the genetic code to the ribosome for translation.
Translation takes place in the cytoplasm, where the ribosome reads the mRNA sequence and, with the help of tRNA, assembles the appropriate amino acids into a polypeptide chain.
- Transcription involves copying genetic information from DNA to mRNA.
- During translation, mRNA is decoded to build proteins.
- Ribosomes facilitate the binding of mRNA and tRNA.
Together, these processes allow the cell to produce proteins that are essential for various biological functions and structures.
