DNA replication is the biological process by which an exact copy of a deoxyribonucleic acid (DNA) molecule is created and it is the basis for biological inheritance. Each of the two strands of the ...

Chromosomal inversions are an important class of genetic variation that link multiple alleles together into a single inherited block that can have important effects on fitness. To study the role of ...

Aluminum stress is an important factor limiting plant growth in acidic soil, and has significant effects on the growth, development and physiological metabolism of Mentha canadensis. However, the ...

Researchers at Tel Aviv University have achieved a breakthrough in drug delivery: they have successfully transported lipid nanoparticles encapsulating messenger RNA (mRNA) to the immune system of ...

If you'd like to learn more about your health, heritage and family history, an at-home DNA test can help you do just that. Justin Jaffe is the Managing Editor for CNET Money. He has more than 20 ...

eLife is a non-profit organisation inspired by research funders and led by scientists. Our mission is to help scientists accelerate discovery by operating a platform for research communication that ...

While most known types of DNA damage are fixed by our cells' in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows.

A team at Nagoya University experimented with ways to uncurl a DNA molecule using pressure applied to liquid flowing in a channel, with the pressure flow providing shear force that uncurled the ...

Researchers have previously tried sticking down one end of a DNA molecule to stretch it out, but found that the thermal fluctuations could still cause movement and blurring. "Stretching DNA refers ...

The authors used a combination of super-resolution imaging techniques and liquid pressure flow to fine-tune the stretch ratio of a DNA molecule, improving the lateral resolution of side-by-side ...

These are the chromosomes numbered 1 to 22 and the sex ... identical twins from two zygotes produced simultaneously. Each DNA molecule has two strands held together by bonds between compounds ...
