What enzymes are involved in gene expression?

Enzymes involved in gene expression include RNA polymerase, which synthesizes RNA from a DNA template during transcription. Additionally, various transcription factors and coactivators modulate RNA polymerase activity, facilitating or inhibiting the transcription process. After transcription, enzymes such as splicing factors and RNA ligases modify the RNA transcript, while ribosomes and associated factors are crucial for translation, the process of synthesizing proteins from mRNA.
