'Jumping genes' key to evolution, researchers reveal - Deccan Chronicle


Deccan Chronicle
Washington: Turns out, almost half of our DNA sequences are made up of jumping genes, which are also known as transposons. Transposons is a DNA sequence that changes its position within a genome, sometimes creating or reversing mutations and ...

Mouse artificial 'embryo' created from stem cells - BioNews


BioNews
The researchers had previously worked on a simpler structure of a mouse embryo consisting of two types of stem cells and a 3D jelly scaffold. In the new study – published in Nature Cell Biology – they used all three types of stem cells: embryonic stem ...

Structure of Memes
Belgium

The main criticism that can be raised against the memetic approach is that memes are difficult to define. What are the elements or units that make up a meme? Does a meme correspond to a complete symphony, or to a symphonic movement, a melody, a musical phrase, or even a single note?

Chromatin Structure
United States

Chromatin is the substance which becomes visible chromosomes during cell division. Its basic unit is nucleosome, composed of 146 bp DNA and eight histone proteins. The structure of chromatin is dynamically changing, at least in part, depending on the need of transcription. In the metaphase of cell division, the chromatin is condensed into the visible chromosome. At other times, the chromatin is less condensed, with some regions in a "Beads-On-
