G0 Stage – Some cells in the adult animals do not appear to exhibit division (e.g., heart cells) and many other cells divide only occasionally, as needed to replace cells that have been lost because of injury or cell death. These cells that do not divide further exit G1 phase to enter an inactive stage called quiescent stage (G0) of the cell cycle. Cells in this stage remain metabolically active but no longer proliferate unless called on to do so depending on the requirement of the organism
🧬 G₀ Phase – Quiescence in the Cell Cycle In adult animals, not all cells…

A gene is defined as the functional unit of inheritance.The DNA sequence coding for tRNA or rRNA molecule also define a gene.Inheritance of a character is also affected by promoter and regulatory sequences of a structural gene. Hence, sometime the regulatory sequences are loosely defined as regulatory genes, even though these sequences do not code for any RNA or protein. The DNA sequence coding for tRNA or rRNA molecule also define a gene
What is a Gene? A gene is the functional unit of inheritance. It carries the…
Bacteria like E. coli divide every 20 minutes. But their DNA — about 4.6 million base pairs — takes about 38 minutes to replicate at 2000 base pairs per second. So how do they manage it?

Kingdom Monera -NCERT-NEET-Bacteria are the sole members of the Kingdom Monera. They are the most abundant micro-organisms. Bacteria occur almost everywhere. Hundreds of bacteria are present in a handful of soil. They also live in extreme habitats such as hot springs, deserts, snow and deep oceans where very few other life forms can survive. Many of them live in or on other organisms as parasites
