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).

In Biology 101, we learn that RNA is a single, ribbon-like strand of base pairs that is copied from our DNA and then read ...

Their model, called Difface, applies single DNA nucleotide differences to 3D facial point clouds, or sets of data points that represent the exterior surface of a face. When tested on a Han Chinese ...

Article continues after sponsor message On the cultural front, April 25, 1953, is notable for the publication of the discovery of the DNA double helix structure by James Watson and Francis Crick.

Abstract: A fiber-optic DNA biosensor with temperature compensation for the specific detection of label-free deafness gene is proposed and demonstrated. The biosensor is fabricated by splicing a ...

We therefore proposed that a reduced level of FEN1 in the striatum would contribute to the high level of TNR instability seen in the striatum of HD animals, because of impaired coordination between ...

is asking for new DNA testing. Conahan is also believed to be investigated as a serial killer who murdered men from North Port to Fort Myers. He was labeled the “Hog Trail Killer,” and ...

Within DNA is a unique chemical code that guides your growth, development, and function. The code is determined by the arrangement of the following four chemicals known as nucleotide bases ...

This process slows down degradation and preserves their structure in a "glassy" state. To explore the mammoth's genome architecture, Rodríguez and his colleagues extracted DNA from a piece of ...

Each nucleotide contains a phosphate, a 5-carbon sugar molecule and a nitrogenous base. RNA only has one strand, but like DNA, is made up of nucleotides. RNA strands are shorter than DNA strands. RNA ...
