Why must DNA replicate from 5' to 3'? Why does DNA replicate? How does DNA replication begin? Why does DNA supercoiling happen? How are DNA replication and protein synthesis different? Why does DNA require an RNA primer during replication?
Although replicating cells in development may be less responsive to neurotoxicants than differentiated neurons, the cell replication process is a major target for neurotoxic damage in other ways. For instance, developing cells must maintain a fixed pattern of mitosis until differentiation is triggered ...

Cell Cycle and DNA Replication: How Does DNA Replicate in Preparation for Cell Division?What Is the Cell Cycle? Cells are structural and functional units of organisms. All cells contain DNA, which encodes all the genetic information of an organism. The DNA in each cell can be transmitted to ...
Replication primarily occurs at the synthesis phase (S phase) of the cell cycle, when the cell must copy the millions of nucleotides (nts) that form its genome with precision. This is facilitated by orchestrated replication of clustered DNA termed replication units, which are activated at ...
Accurate chromosomal DNA replication is essential to maintain genomic stability. Genetic evidence suggests that certain repetitive sequences impair replication, yet the underlying mechanism is poorly defined. Replication could be directly inhibited by th
DNA replication initiates from replication origins firing throughout S phase. Debate remains about whether origins are a fixed set of loci, or a loose agglomeration of potential sites used stochastically in individual cells, and about how consistent thei
Every time a cell divides, its entire genetic and epigenetic information must be accurately replicated. In eukaryotic cells this occurs during the S-phase of the cell cycle through the activity of hundreds to thousands of replication origins (ORIs) distributed along their large genomes, in a conte...
The Cell Cycle:The cell cycle, or cell-division cycle, is the series of events that take place in a cell resulting in the duplication of the cell's DNA and the division of cytoplasm and organelles to produce two identical daughter cells. The cell-division cycle is a vital ...
What must happen before meiosis can begin? What happens directly after prophase? What happens during prophase? What happens to the zygote of Charophytes? In mitosis in human cells are all 46 chromosomes duplicating concurrently to yield 92 chromosomes before cell division? And in what phase of mi...
