DNA molecules are large and complex. They carry the genetic code that determines the characteristics of a living organism. The diagram shows the relationship between the cell, its nucleus, the ...

In the late nineteenth century, a German biochemist found the nucleic acids, long-chain polymers of nucleotides, were made up of sugar, phosphoric acid, and several nitrogen-containing bases.

Genes are the blueprints of life. Genes control everything from hair color to blood sugar by telling cells which proteins to make, how much, when, and where. Genes exist in most cells. Inside a ...

The basic pattern of genomic DNA methylation is established at the time of embryo implantation through a wave of de novo methylation, but CpG islands are protected through a mechanism that ...

In most cells, DNA is wrapped around proteins called histones, allowing it to be loosely packed and accessible for gene activity. However, in sperm cells, histones are replaced by protamines, which ...

A novel technique to visualize gene-active and gene-repressive DNA regions in living cells, developed by a ...

Research shows UV radiation modifies 3D genome structure, affecting DNA damage response and gene activity, offering insights ...

This image depicts the chemical structure of cytosine. It shows a hexagonal ring with nitrogen atoms at positions 1 and 3, and a primary amine group attached to carbon 4. The two remaining positions ...

Chemical structure of guanine, showing its double-ring purine structure and the functional groups involved in hydrogen bonding with cytosine. (Image: Public Domain) Guanine has the chemical formula ...

A new study in the journal Human Gene Therapy indicates that DNA impurities derived from plasmid and host cell DNA are ...

The small study in patients with a rare disorder that causes liver and lung damage showed the potential for precisely targeted infusions. By Gina Kolata Researchers have corrected a disease ...
