Apr 6, 2024 · The nucleolus is a structure within a cell's nucleus that plays a critical role in the life of a cell. This small but mighty organelle is responsible for several important functions, including the synthesis and assembly of ribosomes. In this article, we will explore the nucleolus, its structure and function, and its role in maintaining the health of animal cells.

Apr 8, 2024 · Transcription of DNA. DNA transcription is the process by which the genetic information contained within DNA is re-written into messenger RNA (mRNA) by RNA polymerase. This mRNA then exits the nucleus, where it acts as the basis for the translation of DNA. By controlling the production of mRNA within the nucleus, the cell regulates the rate of ...
Apr 19, 2024 · Definition. A cell cycle is a series of events that takes place in a cell as it grows and divides. A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.
