In a study published in Nature, researchers report the successful in vitro reconstitution of meiotic DNA double-strand breaks ...

Biology lectures teach students that when a cell’s replication machinery comes together, DNA polymerase takes off down the double-helix like a car on a highway ...

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

The DNA repair and replication pathways converge on a common final step in which the continuity of the repaired DNA strand is restored by DNA ligase, an enzyme that converts nicks into phosphodiester ...

RNA polymerase moves along the DNA strand. Free RNA nucleotides form hydrogen bonds with the exposed DNA strand nucleotides by complementary base pairing to form a strand of mRNA: Note - RNA ...

For the first time, the team has mapped the activity of repair proteins in individual ... Such damage can lead to breaks in the DNA strand. If DNA damage is not properly repaired, mutations ...

Different cells have different activities. By controlling protein synthesis within each cell, the genes that make up DNA control the ... can be working on a single strand of mRNA at once.

A study published in Nature Communications and conducted by researchers from the Institute of Physics of the Chinese Academy of Sciences revealed new ...
