The signal peptides are … Web31 mei 2024 · In prokaryotes, protein synthesis, the process of making protein, occurs in the cytoplasm and is made of two steps: transcription and translation. …. Translation occurs at the same time that transcription is happening in prokaryotes. Ribosomes attach to the mRNA and tell tRNA to go get the correct amino acids.

WebThe process of protein synthesis does not occur constantly in the cell, but rather at intervals followed by periods of genetic “silence.” Thus, the process of gene expression is regulated and controlled by the cell. The control of gene expression can occur at several levels in the cell. For example, genes rarely operate during mitosis.

WebOne key step for regulation is translation initiation. In order for translation to begin, the ribosome, an RNA-and-protein complex that houses translation, must assemble on the … WebDNA is the molecule which controls the synthesis of proteins. Proteins are used for growth and repair and also as enzymes, in which form they catalyse all other cellular activities. Thus DNA is able to exert a controlling influence over the whole cell and ultimately, the whole organism.

WebGenetic Control of Enzyme Production in Prokaryotes O Genes control protein synthesis. Some proteins are required all the time by cells whilst others are only needed in specific circumstances and so are not made all the time.
