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 remain between chromosomes after cell division, chromosomes become improperly segregated, resulting in genetic ...

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 ...

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 ...

DNA is susceptible to damage caused by errors committed during replication and by environmental factors ... DNA ligases catalyze the joining of a 5’-phosphate-terminated strand to a ...

During DNA replication, the double helix unwinds ... It consists of an adenine base, a ribose sugar, and three phosphate groups. The hydrolysis of ATP releases energy that is used to drive various ...
