People also ask, where is the gene expressed?
The ribosomal complex in eukaryotes is larger and more complicated than in prokaryotes. In addition, the processes of transcription and translation are divided in eukaryotes between the nucleus (transcription) and the cytoplasm (translation), which provides more opportunities for the regulation of gene expression.
In this way, are all genes expressed?
always expressed Certain key genes are made at all times under all circumstances. – E.g. Ribosomal proteins, tRNAs, RNA polymerase, glycolysis enzymes – These are called constitutive genes. Other genes are made only at certain times or in certain conditions.
Messenger RNA (mRNA) Messenger RNA (mRNA) is a single-stranded RNA molecule that is complementary to one of the DNA strands of a gene. The mRNA is an RNA version of the gene that leaves the cell nucleus and moves to the cytoplasm where proteins are made.
