Summary
The genome
Area of Science:
- Genetics and genomics
- Molecular and cell biology
Background:
- Genome duplication, or replication program, involves the spatial and temporal organization of replication initiation sites.
- Changes in replication profiles correlate with cell fate during development and in diseases.
- The significance of distinct replication programs during S phase is not well understood.
Purpose of the Study:
- To investigate the role of the replication program in genome maintenance.
- To explore how DNA replication organization influences the response to replication stress.
Main Methods:
- Focus on the interplay between replication program and genome maintenance.
- Analysis of the ATR/Rad3 checkpoint pathway's role in mediating replication stress response.
Main Results:
- The organization of DNA replication directs the cellular response to replication stress.
- This response is mediated by the ATR/Rad3 checkpoint pathway.
- Replication program influences the pattern of genome instability across chromosomes.
Conclusions:
- The replication program plays a crucial role in genome maintenance and stress response.
- Understanding the replication program offers new insights into genome instability and associated pathologies.
- This research highlights the biological importance of specific S phase replication programs.

DNA Replication
59.2K
DNA replication involves the separation of the two strands of the double helix, with each strand serving as a template from which the new complementary strand is copied. After replication, each double-stranded DNA includes one parental or “old” strand and one “new” strand. This is known as semiconservative replication. The resulting DNA molecules have the same sequence and are divided equally into the two daughter cells.

The DNA Replication Fork
40.9K
An organism’s genome needs to be duplicated in an efficient and error-free manner for its growth and survival. The replication fork is a Y-shaped active region where two strands of DNA are separated and replicated continuously. The coupling of DNA unzipping and complementary strand synthesis is a characteristic feature of a replication fork. Organisms with small circular DNA, such as E. coli, often have a single origin of replication; therefore, they have only two replication...

Chromosome Replication
10.6K
Before a cell can divide, it must accurately replicate all of its chromosomes, including the DNA and its associated histone and non-histone proteins. This process begins at numerous origins of replication during the S phase of the cell cycle in each of a cell’s chromosomes simultaneously. Certain nucleotides can act as origins of replication, but these sequences are not well defined - especially in complex, multi-cellular, eukaryotic species. The length of DNA that spans an origin...

S-Cdk Initiates DNA Replication
5.7K
The cell cycle is a series of events leading to DNA duplication followed by the division of cell content to form two daughter cells. The cell cycle progresses in four stages—the cell increases in size (gap 1 or G1-phase), duplicates its DNA (synthesis or S-phase), prepares to divide (gap 2 or G2-phase), and divides (mitosis or M-phase).

Genomic DNA in Prokaryotes
48.6K
The genome of most prokaryotic organisms consists of double-stranded DNA organized into one circular chromosome in a region of cytoplasm called the nucleoid. The chromosome is tightly wound, or supercoiled, for efficient storage. Prokaryotes also contain other circular pieces of DNA called plasmids. These plasmids are smaller than the chromosome and often carry genes that confer adaptive functions, such as antibiotic resistance.
