Scientists have finally captured footage of the microscopic machinery that allows our cells to copy DNA—a fundamental process ...

Every day, billions of cells in your body divide, helping to replace old and injured cells with new ones. And each time this ...

Mitochondrial deoxyribonucleic acid (mtDNA) is essential for cellular energy production and overall cell function. Abnormalities in mtDNA are linked to various diseases and are also implicated in ...

DNA replication is one of the most basic processes that occurs within a cell. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information ...

Aa Aa Aa Eukaryotic genomes are replicated with almost absolute fidelity every time cells divide. However, conditions for DNA replication are rarely ideal. For example, environmental toxins or ...

Nucleotides are abundant in the cell's nucleus. Nucleotides are the units which, when linked sugar to phosphate, make up one side of a DNA ladder. During DNA replication, special enzymes move up ...

Researchers have now uncovered the role of mitochondrial transcription elongation factor in maintaining the balance between ...

Since HIV’s discovery in the 1980s, scientists have come a long way in understanding the different steps required for its assembly and maturation. Researchers knew, for instance, that HIV wraps its ...

If you've looked at the activity (or even the text version of the activity), you know how a section of DNA instructs a cell how to make a protein. Actually, that's DNA's main purpose: to make ...

The emergence and persistence of highly pathogenic avian influenza (HPAI) A(H5N1) viruses in terrestrial mammals, particularly dairy cattle, demand urgent attention from the scientific community and ...

A study links the loss of DNA methylation across the genome—as is common in cancer—to the disruption of the 3-D compartments that organize the genome and to the timing of DNA replication. Cell lines ...
