Data obtainable from this type of labeling paradigm are origin position, interorigin distance, timing of firing of neighboring origins, fork speed, and obstacles to fork progression.
By repressing expression of the genes encoding these CDK inhibitors, c-Myc eliminates two major obstacles to cycle progression.
Bulky lesions, such as those induced by UV, pose obstacles to the progression of the replication fork (Sale et al. 2012).
Supplementary origins and low inter-origin distance ensure faster and more efficient replication in embryonic systems, facilitating the bypass of eventual obstacles to replication progression (Woodward et al, 2006).
If we assume that the only possible obstacles to replication progression in oppositely oriented rrn are R-loops and RNA Pol, then the growth defect and the high level of non-migrating Inv-fragment in InvA dinG uvrD and InvBE dinG uvrD mutants that overproduce RNaseH can logically be interpreted as the occurrence of collisions of replication forks with RNA Pol.
Such a delay may, for example, occur in response to DNA damage, or other obstacles to cell-cycle progression.
But in Full Throttle, the first major obstacle to your progression is dealt with by grabbing a dude's nose-ring and slamming his head against a bar.
Second, duplicated segments could adopt a complex secondary structure that can impose an obstacle to the progression of replication forks [ 116, 117].
These adducts create covalent bonds linking the two DNA strands in a duplex, generating an abnormal structure that poses a physical obstacle to the progression of cellular machinery like DNA replisomes [1,2].
If you don't evaluate honestly and sincerely, then this recollection gives little benefit or meaning, will seem dull and pointless or even worse, it can make your mind simply unable to investigate and understand the mind and the body which for a practitioner dedicated to the path will be a major obstacle to further progression.
Mouse prostate cancer modeling presents unique obstacles to the study of spontaneous tumor initiation and progression due to the anatomical location of the tissue.
