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 ...

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 ...

Cells are the smallest units of life. But even within the same tissue or organ, they are not all identical. New variations arise continuously during cell proliferation. While genetic mutations alter ...

In this type of pairing, adenine (A) forms two hydrogen bonds with thymine (T) in DNA or uracil (U) in RNA, while guanine (G) forms three hydrogen bonds with cytosine (C). These base pairs are highly ...
