This base-to-base bonding is not random; rather, each A in one strand always pairs with a T in the other strand, and each C always pairs with a G. The double-stranded DNA that results from this ...

Genes exist in most cells. Inside a cell is a long strand of the chemical DNA (deoxyribonucleic acid). A DNA sequence is a specific lineup of chemical base pairs along its strand. The part of DNA ...

excess flexibility of the DNA strand and the subsequent mispairing of bases is another. Environmental exposure to certain chemicals, ultraviolet radiation, or other external factors can also cause ...

But various combinations of those four bases -- say ... it makes a copy of its DNA instructions for the new cell. The twisted double strand structure -- the famed double helix -- unwinds and ...

Researchers have revealed new details about the CRISPR-Cas5-HNH/Cascade complex, a variant of the type I-E CRISPR-Cas system, ...

Specifically, instead of the four bases from which DNA is constructed linking to each other like normal (adenine to thymine on the opposite strand, cytosine to guanine) cytosines on the same ...

Researchers have uncovered a way to manipulate DNA at the atomic level using electric field gradients to control nitrogen ...

During DNA replication, the complementary base pairing of thymine with adenine ensures the accurate copying of genetic information. DNA polymerase enzymes use the existing DNA strand as a template and ...

These mechanisms can detect and correct different types of DNA damage, such as base mismatches, single-strand breaks, and double-strand breaks. DNA repair is essential for preventing the accumulation ...

Forensic DNA profiling uses polymerase chain reaction (PCR) to amplify short tandem repeats (STRs), which are highly variable DNA regions, typically with four repeating bases. This variability ...

Through base editing, drugs replace single nucleotide in the DNA strand with another, without making double-strand breaks (DSBs) in the gene. Other CRISPR-based therapies generate a DSB at a ...
