Nucleic acids are complex biological molecules that store and transmit genetic information in all living organisms. They are essential for the survival and reproduction of life on Earth. The two main ...

During DNA replication, the unwinding of strands leaves a single strand vulnerable. How does the cell protect these strands from damage?

Researchers have discovered a plausible evolutionary setting in which nucleic acids – the fundamental genetic building blocks of life – could enable their own replication, possibly leading to life on ...

When people eat, they ingest the nucleic acids that reside in all living things. The compounds in these acids could inhibit the growth of cancer cells, according to findings published in PLOS ONE by ...

Changes in genes have been linked to the development of different diseases for a while. However, it's not exactly clear what ...

Synthetic nucleic acid analogues are known as xeno nucleic acids (XNAs), which is appropriate because “xeno” means “alien” or “strange.” To date, most XNAs have been just a little strange, containing ...

A new study has illuminated an important process that occurs during cell division and is a likely source of DNA damage under some circumstances, including cancer. A new study from scientists at the ...

Nucleic acids are long chains of nucleotides found in all living organisms. Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are two common nucleic acids responsible for providing genetic ...
