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

DNA is a complex molecule that consists of two strands coiled around each other to form a double helix structure. Comparison of a single ... The double helix unwinds, and each strand serves as a ...

Researchers have mapped 50,000 of DNA's mysterious "knots" in the human genome ... on the same DNA strand pair with each other, creating a four-stranded, twisted structure protruding from the ...

DNA transcription is the vital first step needed for switching on our genes. For a gene to be switched on, it must be acted upon by an enzyme called RNA polymerase. This is a molecular machine which ...

Nature provided the model that gave scientists their first glance into the unique structure ... round of DNA replication, DNA polymerase and the DNA repair enzymes fill in the other strand.

Inside a cell is a long strand ... DNA. It is also frequently used for other benefits, like wildlife studies, paternity testing, body identification, and in studies pertaining to human ...

the helix structure is unwound special molecules break the weak hydrogen bonds between bases, which are holding the two strands together this process occurs at several locations on a DNA molecule ...

When a cell divides, it makes a copy of its DNA instructions for the new cell. The twisted double strand structure -- the famed double helix -- unwinds and the strands separate. The nucleotides (A ...

During cell division the two strands separate and on each strand a new "other half" is built, just like the one before. This way DNA can reproduce itself without changing its structure -- except ...

The enzyme RNA polymerase attaches to the DNA in a non-coding region just before the gene. RNA polymerase moves along the DNA strand ... acids to finalise the structure.
