Donald Coffey, a longtime professor at Johns Hopkins University, discovered the nuclear matrix within cells and its role in DNA replication. Telomeres are repetitive, noncoding sequences that cap the ...

How cells respond to mitochondrial DNA (mtDNA) damage is not fully understood. This study uncovers a mechanism of mtDNA ...

The DNA repair and replication pathways converge on a common final step in which the continuity ... The viral ligases do not form stable complexes with the following ligands: (i) DNA containing a ...

Each nucleotide consists of alternating sugar and phosphate sections with one of the four different bases attached to the sugar.

Replication of DNA DNA replication is the process by which ... Genomic sequencing Genomic sequencing is the process by which the sequence of nucleotide bases is determined for individual genes ...

In later stages, more concerned with differentiation than proliferation, it is thought that epigenetic marking restrains most potential origins and restricts the speed of DNA replication and cell ...

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 ... so that the wrong nucleotide is placed in position.

The reliability of the DNA replication process depends on genome ... the researchers detected multiple structural variations, including nucleotide deletions, duplications and translocations ...

DNA mutations are changes in the nucleotide sequence of the DNA molecule. Mutations can occur spontaneously due to errors during DNA replication or as a result of exposure to mutagens (e.g., UV ...

During DNA replication, the double helix unwinds ... NAD + is a coenzyme that plays a crucial role in cellular metabolism. It consists of an adenine nucleotide joined to a nicotinamide nucleotide. NAD ...
