Watson and Crick's discovery of DNA structure in 1953 revealed a possible mechanism for DNA replication. So why didn't Meselson and Stahl finally explain this mechanism until 1958 ...

Whether it is a microbe, a rose, or a dolphin, any form of life gets its building and operating instructions from the molecule of life, DNA ... by a combination of three of the chemical bases ...

This forms two replication forks that move along the DNA, replicating as they go. DNA is always synthesized in the 5'-to-3' direction, meaning that nucleotides are added only to the 3' end of the ...

And each time this happens, your entire genetic library—your genome, which totals more than 3 billion base pairs ... to ...

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

A study links the loss of DNA methylation across the genome—as is common in cancer—to the disruption of the 3-D compartments that organize the genome and to the timing of DNA replication. Cell lines ...

An article by UAB professor Joan-Ramon Daban analyzes in depth the physical problems associated with DNA packaging that have ...

1916) and Rosalind Franklin were also studying DNA. The Cambridge team's approach was to make physical models to narrow down ... and can only be shared among three winners. Were she alive, would ...

There are four different types of nitrogen bases in DNA. They include: adenine (A) cytosine (C) guanine (G) thymine (T) The two strands of DNA form a 3-D structure called a double helix.
