The nucleus is the control center of a cell. The nucleus controls the cell's growth and reproduction and contains the cell's DNA.Know More
The nucleus of a cell contains most of that cell's genetic material. Its job is to maintain the integrity of the cell while controlling its activities. The nucleus is separated from the cytoplasm by a membrane called a nuclear envelope.This helps to protect the cell's chromosomes which is where the DNA is located.
The nucleus was first discovered by microscopist Antonie van Leeuwenhoek in the mid-1600s while he was examining the red blood cells of salmon. The nucleus was again observed in 1804 by Franz Bauer and botanist Robert Brown, who described the nucleus in great detail in 1831.Learn More
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 controls protein synthesis in a cell's cytoplasm in the sense that the genetic codes contained in the nucleus determine the sequence of amino acids that are assembled to build the proteins. This is the only aspect of protein assembly directly controlled by the nucleus, while other mechanisms and structures in the cell are responsible for detecting which proteins are needed. The nucleus serves as a protein code database.Full Answer >
Prokaryotic cells lack a nucleus. Bacteria and members of the domain Archaea are prokaryotes, while plants, animals, protists and fungi are eukaryotes. Prokaryotic cells lack the membrane-bound organelles found in eukaryotic cells.Full Answer >
Transcription occurs in the nucleus of the cell. The process involves making a strand of messenger ribonucleic acid (RNA) using deoxyribonucleic acid (DNA) as a template. Transcription is the first step in making a protein.Full Answer >
