Revolutionary novel method can manipulate the shape, packing of DNA: Study
Updated : 2 years, 9 months ago IST
A human cell contains around 2 metres of DNA, which contains an individual's important genetic information. If all the DNA contained within a single person were unwound and stretched out, it would cover an astonishing distance - enough to reach the sun and back 60 times over. The cell compac

Study finds how worm embryos produce specific, pluripotent cells
Updated : 2 years, 11 months ago IST
Researchers have discovered how specific proteins within roundworm chromosomes enable their offspring to produce specialised cells generations later, a startling discovery that challenges the conventional wisdom that hereditary information for cell differentiation is primarily ingrained with

Study reveals how whole genome doubling drives cancer
Updated : 2 years, 12 months ago IST
Two to three metres of DNA can fit inside a single cell, thus it can only be stored by being wound tightly into coils. The answer is chromatin, a compound of DNA encased in histone-like proteins. This complex gradually folds into the multi-layered arrangement of loops, domains, and compartme

Scientists make breakthrough by sequencing endangered sharks' genomes
Updated : 3 years, 2 months ago IST
It's a startling image that describes a milestone in conservation science for sharks. Professor Shivji, Professor Michael Stanhope and their collaborators have glanced back in history by sequencing to chromosome level the genomes (entire genetic blueprint) of great hammerhead and shortfin ma

Maryland [US], October 7 (ANI): The arrangement of human retinal cell chromatin, the fibres that wrap 3 billion nucleotide-long DNA molecules into compact structures that fit into chromosomes within each cell's nucleus, was mapped by National Eye Institute researchers. The resultant complet

Portsmouth [England], September 27 (ANI): A genetic mutation causes Duchenne muscular dystrophy (DMD), which affects one in every 5,000 boys born. Because the affected gene is located on the X chromosome, girls are carriers of the mutant gene but only very rarely develop the disease (one

Scientists discover new kind of synapse in neurons' tiny hairs
Updated : 3 years, 6 months ago IST
Washington [US], September 3 (ANI): Scientists have discovered a new kind of synapse in the tiny hairs on the surface of neurons. The commonly overlooked protrusions called primary cilia contain special junctions that act as a shortcut for sending signals quickly and directly to the cell's n

Researchers find oldest case of rare genetic condition
Updated : 3 years, 6 months ago IST
Washington [US], August 29 (ANI): Researchers have found evidence of a super rare genetic condition that gives men an extra X chromosome, reporting the oldest clinical case of Klinefelter Syndrome to date.

Study reveals the reasons why many IVF embryos fail to develop
Updated : 3 years, 7 months ago IST
New York [US], July 21 (ANI): A fertilised egg does not ensure successful reproduction in humans. Within days following fertilisation, the majority of embryos stop growing and die, typically due to an abnormally high number of chromosomes. The majority of these faults, according to new resea

Loss of male sex chromosome leads to earlier death for men: Study
Updated : 3 years, 8 months ago IST
Washington [US], July 16 (ANI): New research shows the loss of the male sex chromosome as many men age causes the heart muscle to scar and can lead to deadly heart failure. The finding may help explain why men die, on average, several years younger than women.
