A new study published in Nature Structural & Molecular Biology reveals how the fundamental enzyme called DNA polymerase delta operates during DNA replication, making a copy of the genetic code that ...

For all species, the process of DNA replication requires the use of multiple different DNA polymerase enzymes. The primary function of these unique multisubunit enzymes is to ensure optimal DNA ...

Sometimes a replicating cell must choose the lesser of two evils. For example, when a replicating cell is stressed, it may struggle to pair bases against its single-stranded DNA (ssDNA) template, even ...

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified. A protein that is involved in determining which enzymes cut or unwind DNA ...

Failures in DNA replication can lead to cancer, birth defects or other harm Video shows single pieces of double-helix DNA being copied Single-molecule view gives new insights into this process ...

Almost all life on Earth is based on DNA being copied, or replicated. Now for the first time scientists have been able to watch the replication of a single DNA molecule, with some surprising findings.

32 P-label is introduced by incoming dGT 32 P molecule. The arrows indicate the sites of enzymatic hydrolysis. The bases of the template DNA strand are designated as clear boxes, and the bases in the ...

This video shows replication of individual pieces of double stranded DNA. This is the first time DNA replication -- arguably, the fundamental process of life on Earth -- has been observed directly.
