Learn about the purpose of the nucleus in a cell and see why the nucleus is important. Study the functions and roles of the nucleus and understand the DNA process. Related to this QuestionWhat does a nucleus do in a plant cell? What does a nucleus look like in a plant cell? What is ...
What impact does the type and quality of DNA or RNA have on transfection success? Genetic material with higher purity will routinely deliver better transfection outcomes. Identifying contamination by lipopolysaccharides (endotoxins) that are introduced by bacteria during the manufacturing process is critical...

Many question, “What does the Cell cycle have to do with cancer?”The cell cycle is a process in which cells develop and go on to divide.The cell cycle lies in the metaphorical heart of cancer. The cell cycle is a series of pathways by which a cell is signaled and continues to grow...
Cells can vary between 1 micrometer (μm) and hundreds of micrometers in diameter. Within a cell, a DNA double helix is approximately 10 nanometers (nm) wide, whereas the cellular organelle called a nucleus that encloses this DNA can be approximately 1000 times bigger (about 10 μm). Se...
