Nucleic acids (DNA or RNA) are polymers of nucleotides ... Now, a photoswitchable DNA structure-specific, small-molecule ligand enables reversible, light-controlled regulation of gene expression ...

Levene made his initial proposal in 1919, discrediting other suggestions that had been put forth about the structure of nucleic acids. In Levene's own words, "New facts and new evidence may cause ...

If DNA bridges persist between chromosomes during cell division, chromosomes are abnormally segregated, leading to genetic ...

Researchers utilized recently published telomere-to-telomere genomes of humans, chimpanzees, bonobos, gorillas, and two orangutans to predict where DNA sequences might form alternative structures ...

The yeast nuclear endonuclease Rnt1 has a well-characterized role in the maturation of many ncRNA precursors. However, the scope and consequence of its function in mRNA degradation pathways is much ...

Somatic hypermutation (SHM) of immunoglobulin variable (V) regions modulates antibody-antigen affinity is initiated by activation-induced cytidine deaminase (AID) on single-stranded DNA (ssDNA).

If DNA bridges remain between chromosomes after cell division, chromosomes become improperly segregated, resulting in genetic ...

Ivy: Dull dull dull dull dull dull dull dull dull dull dull dull dull. Posey: No, you're not. Ivy: Not me! The flowers. I planted all these carnations months ago and I thought they'd be colourful ...
