What if we told you that we’re all related? Mitochondrial DNA shows that everyone alive today shares the same two ancient ancestors from hundreds of thousands of years ago.

The Y chromosome’s genetic puzzle is finally complete

                                        INTRODUCTION: Mitosis is a type of cell division that takes place in living organisms and it is commonly defined as the process of duplication of chromosomes in eukaryotic cells and distributed during cell division.  The process where a single cell divides resulting in two identical cells, each resulted cell contains the same number of chromosomes and…

silly edit in anatomy/physiology video

Put sound on!! (please, that's like the whole joke...)

Was looking at stuff for my Anatomy, Fysiology and Pathology class and this edit just sends me. I had to share. You get used to the guy talking and explaining then suddenly...!! This is the first of this kind of edit in the video too, it comes so unexpected.

OG video: https://www.youtube.com/watch?v=izOa3-AX8zQ

@venterry Hi! You know, funny coincidence, when I went to share this silly video editing choice the first thing I saw was your reblog of another wacky edit, so... I thought maybe you'd appreciate this too. Sorry if you don't like to be mentioned I just thought you might like it and the coincidence was too strong to resist...

artfight friendly fire for my twinnie (metaphysics on af) of her bizarre character created during middle school

page 194 - am I in one of those police dramas, a single bulb hanging over me handcuffed to a table in the interrogation room. No one is asking anything of me, questions or actions. Am I meant to be doing something to show my worth, sharing something so they know I'm peaceable and can be left alone, or just staying in the bright light's cone so I can't see what's outside? So I can't see who is outside it, who I might talk to or collaborate with.

Ever lick a mystery bear after eating a mystery fungus and hours into the trip you wonder. See lights and wonder, metaphorically.

Women have two x chromosomes. Men have one y chromosome and one ex chromosome. The very ideal that women can understand the male experience is fucking laughable at this point isn't it.

FISH Hybridization System

A FISH (Fluorescence In Situ Hybridization) Hybridization System is a specialized laboratory instrument used for detecting and analyzing specific DNA or RNA sequences within cells or tissues. Highly-efficient, stable and convenient operation.

Bundles of Joy

Breaking a cell exactly in half requires huge feats of tiny engineering. Hundreds of proteins oversee the process of mitosis – but arguably the most crucial job, separating the precious DNA, still holds a few mysteries. Here scientists using super-resolution microscopy watch as microtubules – somewhere between fishing lines and microscopic scaffolding – (highlighted in green) first reach out from opposite sides of the cell towards the DNA (purple). The tubules meet in a criss-cross network seen from two different angles (top and bottom rows, left). Later in mitosis (middle and right) the tubules form thick bundles that bridge the gap between the different sides of the cell as the DNA lines up in the centre. Researchers believe kinetochores, linkers between DNA and microtubules, help to coordinate these overlap bundles,, which in turn guide the overall machinery as it begins the careful job of pulling the DNA apart.
