WebMany genes are controlled by several different transcription factors, with a specific combination needed to turn the gene on; this is particularly true in eukaryotes and is … WebFigure 9.22 Eukaryotic gene expression is regulated during transcription and RNA processing, which take place in the nucleus, as well as during protein translation, which takes place in the cytoplasm. Further regulation may occur through post-translational modifications of proteins. WebIn eukaryotic cells like photoreceptors, gene expression is often controlled primarily at the level of transcription. However, that doesn't mean transcription is the last chance for regulation. Later stages of gene expression can also be regulated, including: RNA processing, such as splicing, capping, and poly-A tail addition signs of infection in your body

How most eukaryotic genes are controlled

WebLong answer: Most eukaryotic cells only divide in the presence of mitogens. Mitogens stimulate cell division by increasing the amount of G1 cyclins, which trigger cells to enter Start (i.e., the point in G1 which cells commit to divide). G1 cyclins regulate entry into Start by turning on expression of G1/S and S cyclins.
