Cell division is an essential process by which cells replicate to ensure growth, development, tissue repair, and reproduction in living organisms. The two primary types of cell division are mitosis and meiosis. Mitosis leads to the formation of two genetically identical daughter cells, while meiosis results in four genetically distinct […]
Transcription is the biological process where the genetic information in DNA is copied into messenger RNA (mRNA) for protein synthesis. It is the first step in gene expression and occurs in the nucleus of eukaryotic cells and the cytoplasm of prokaryotic cells. Transcription involves several key enzymes and regulatory mechanisms […]
DNA replication is the biological process by which a cell duplicates its genetic material before cell division, ensuring that each daughter cell receives an identical copy of the parent DNA. This process is semiconservative, meaning each new DNA molecule consists of one original strand and one newly synthesized strand. DNA […]
The cell cycle is a series of events that take place in a cell leading to its growth, replication, and division into two daughter cells. It is divided into two major phases: interphase and the M phase (mitosis or meiosis). Interphase is further divided into the G1, S, and G2 […]
Post-translational modifications are chemical changes made to proteins after translation, which affect their function, stability, and localization. These modifications include processes such as phosphorylation, glycosylation, acetylation, and ubiquitination. They can activate or deactivate enzymes, alter protein interactions, or target proteins for degradation. Such modifications are crucial for regulating protein activity, […]
