B iology lectures teach students that when a cell’s replication machinery comes together, DNA polymerase takes off down the ...

Meiotic recombination generates genetic diversity and promotes proper chromosomal segregation of parental chromosomes. This ...

and it therefore can inhibit recombination by blocking Rad51's access to the single strand needed for invasion. In yeast, however, binding of Rad51 to ssDNA is enhanced by the proteins Rad52 and ...

Focusing on the schematic illustration in a, two DNA polymerase molecules are active at the fork at any one time. One moves continuously to produce the new daughter DNA molecule on the leading ...

The single stranded mRNA (2) is translated into protein in the cytoplasm ... MHC I complexes are presented on the cell surface (6), binding cytotoxic CD 8+ lymphocytes, and inducing a cell ...

RNA is usually single-stranded but can form complex secondary structures through base pairing within the same strand. DNA serves as the repository of genetic information in cells. It encodes the ...

The advent of "mass cytometry" in 2009 allowed the simultaneous quantification of 50 proteins in single cells, and a more ...

2020) we found that the dsDNA strands are separated on binding to the filament ... This intermediate shows a mini filament, with its nine RecA proteins in gold and its single-stranded DNA in brown, ...

Dendritic cells—the immune system's best antigen-presenting cells—carry proteins on their surfaces ... and co-delivers them with single-stranded RNA so that the dendritic cells can be ...

This innovative approach involves reading the ionic current response as a single molecule passing through a nanoscale pore, which can be either a biological protein assembly embedded in a lipid ...

STOCKHOLM: This year’s Nobel Prize for Medicine (Physiology) honoured two scientists, Victor Ambros and Gary Ruvkun, for ...

In the late 1980s, Ambros and Ruvkun were postdoctoral researchers in the laboratory of Robert Horvitz, who received the ...
