In a eukaryotic cell, the final stage of protein synthesis takes place in the cytoplasm after the initial stage, which happens in the nucleus. In a prokaryotic cell, there is no need for the second stage of the process.Continue Reading
The information on how to synthesize protein is contained in DNA. The DNA molecules constitute a set of instructions for each cell on how to consume energy, grow, reproduce and expel waste. However, DNA is only the code. To make these code into instructions that parts of a cell can read, ribonucleic acid, or RNA, is needed. Messenger RNA, or mRNA, plays a key part in the process of protein synthesis.
The first stage of protein synthesis is transcription. In a eukaryotic cell's nucleus, segments of the double-stranded DNA molecules are turned into single strands of RNA molecules called transcripts. These transcripts are then processed into mRNA. Prokaryotic cells are different in that their transcripts can serve as mRNA immediately.
The second stage of protein synthesis in a eukaryotic cell is called translation. This takes place in the cell's cytoplasm. During this stage, genetic information is transferred from RNA to protein. Peptide bonds between amino acids are formed and thus protein is synthesized.Learn more about Cells
The organelle that manages cell functions in a eukaryotic cell is the nucleus. Most eukaryotic cells have a single nucleus; however, some organisms may have several nuclei per cell.Full Answer >
The nucleus can be thought of as the control center of a eukaryotic cell because it contains most of the genetic material that carries the instructions for the cell's operations. Inside the nucleus, DNA directs the sequence of chemical steps needed for the synthesis of proteins and, by way of the proteins' action, it controls the metabolism of the rest of the cell.Full Answer >
The nucleus starts the process of maintaining cell homeostasis by generating the protein RNA, or ribonucleic acid, which is released into a cell's cytoplasm. The cytoplasm is the jelly-like substance that holds all the organelles in place. The RNA is gathered by the ribosomes, which replicate the protein as needed.Full Answer >
The basic components of a human cell are the cell membrane, the cytoplasm, the nuclear membrane and the nucleus. Within each of these parts are smaller structures, such as the organelles, which have specialized functions within the cell.Full Answer >
