Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNA replication is one of the most basic processes that occurs within a cell.

undergo a type of cell division known as binary fission. This process involves replication of the cell's chromosomes, segregation of the copied DNA, and splitting of the parent cell's cytoplasm.

Whenever a cell divides -- whether to repair damaged ... scientists lack the ability to closely observe the intricate process of replication. Attempts to do so have relied on chemicals that ...

Often this copying process makes errors, so that the wrong nucleotide is placed in position. The cell can correct these errors, called mutations, but some inevitably get through. How often these ...

When cells express specific ... a required protein. The process is made up of the transcription and translation of DNA sequences. Genome and mutations DNA replication is carefully controlled ...

This fundamental role in cell life makes topoisomerase I an important target for cancer therapies: its inhibition leads to ...

When they applied drugs that damage DNA or target other steps of the nucleic acid replication process, glucose limitation was not an advantage, and the cancer cells died. Under normal conditions, a ...

Whilst the ultimate outcome of the lytic cycle is production of new phage progeny and death of the host bacterial cell, this is a multistep process involving precise coordination of gene transcription ...

In a hair follicle cell, a protein called keratin is made. Lots of it. Many ribosomes can be working on a single strand of mRNA at once. Protein synthesis isn't a slow process, either. A protein ...

Whether archaea or eukaryotes have a similar process also remains an open question. “Eukaryotic cells are much more complicated in different ways,” Sheng said. They have multiple, larger chromosomes, ...
