1. DNA replication - This is the process where a cell makes an identical copy of its DNA before gene expression can occur.
2. Transcription - This step involves the synthesis of RNA molecules from the DNA template using the enzyme RNA polymerase.
3. Splicing - This is the process where non-coding regions called introns are removed from the initial RNA transcript, leaving only the exons.
4. mRNA export - After splicing, the mRNA molecule is exported from the nucleus to the cytoplasm, where it can be used for translation.
5. Translation - This step takes place in the cytoplasm and involves the conversion of the mRNA sequence into an amino acid chain using ribosomes and tRNA molecules.
6. Folding - Once the amino acid chain is formed, the protein must undergo a specific folding process to adopt its functional shape.
