[h] The authors conclude that if replication is defined by a subsequent study finding a sufficiently similar effect size to the original, replication success is not likely even if replications have very large sample sizes. Importantly, this occurs even if replications are direct or exact since heterogeneity nonetheless remains relatively high ...
Replication of DNA always begins at an origin of replication. In yeast, the origins contain autonomously replicating sequences (ARS), distributed throughout the chromosome about 30 kb from each other. They allow replication of DNA wherever they are placed. Each one is 100-200 bp long, and the A element is one of the most conserved stretches.
Slipped strand mispairing (SSM, also known as replication slippage) is a mutation process which occurs during DNA replication. It involves denaturation and displacement of the DNA strands, resulting in mispairing of the complementary bases. Slipped strand mispairing is one explanation for the origin and evolution of repetitive DNA sequences. [1]
Replication stress and its consequences in mitosis. DNA replication stress refers to the state of a cell whose genome is exposed to various stresses. The events that contribute to replication stress occur during DNA replication, and can result in a stalled replication fork. [1] There are many events that contribute to replication stress ...
This stoppage could be permanent or temporary, and could occur in any one of the four cycle phases (G1, S, G2 and M), depending on the status of cells or the activities they are undergoing. [1] During the process, all cell duplication process, including mitosis, meiosis as well as DNA replication, will be paused. [2]

Elton John is sharing a health update about his sight.. On Monday, Nov. 25, the singer-songwriter, 77, said in an interview with Good Morning America that he lost vision in his right eye in July ...
DNA replication is an all-or-none process; once replication begins, it proceeds to completion. Once replication is complete, it does not occur again in the same cell cycle. This is made possible by the division of initiation of the pre-replication complex. [citation needed]
