Plasmolysis in Onion Epidermal Cells – Biology Lab Techniques

First, cut a white onion into 4 to 6 sections. Onion is an ideal model organism to study plasmolysys because its epidermis is easy to peel off and quite resistant. Pick the third leaf from the outside, as it usually shows the best compromise between tissue maturity and integrity. Cut 5mm-wide square sections with a […]

Biological Significance of Mitosis (A’level biology)

hello everyone welcome to my channel I’m Sharmin Today I’m going to teach you biological significance of mitosis okay so growth the two daughter cells formed have the same number of chromosomes as the parent cell and are genetically identical clones these allows growth of multicellular organisms from unicellular zygotes and growth may occur over […]

How this disease changes the shape of your cells – Amber M. Yates

What shape are your cells? Squishy cylinders? Jagged zig-zags? You probably don’t think much about the bodies of these building blocks, but at the microscopic level, small changes can have huge consequences. And while some adaptations change these shapes for the better, others can spark a cascade of debilitating complications. This is the story of […]

12 molecular machines of Christmas | CSL-Notch-Mastermind transcription factor

My molecular machine of today is the CSL-Notch-Mastermind transcription factor complex. This is one of the many molecular machines or complexes which control which proteins are produced during the growth and development of an organism. This complex is extra special because it ensures that nematode worms have Christmas trees. So what do I mean by […]

MIT Engineers program Human Cells to store complex Histories in their DNA.

MIT biological engineers have devised a way to record complex histories in the DNA of human cells, allowing them to retrieve “memories” of past events, such as inflammation, by sequencing the DNA. This analog memory storage system — the first that can record the duration and/or intensity of events in human cells — could also […]
