DNA replication cannot begin until specific checkpoints are passed during the G1 phase of the cell cycle.
DNA replication occurs in the nucleus of the cell.
The origin of replication in an expression plasmid is a specific DNA sequence that allows the plasmid to replicate, or make copies of itself, within a host cell. This sequence is essential for the plasmid to be maintained and passed on to daughter cells during cell division.
Based on how it occurs, it is said to be 'semi-discontinuous' replication.
Activites within the cell cycle are monitered and controlled at specific stages, or checkpoints. Checkpoints in the life of a cell are like checkpoints during a mountain bike race. Officials monitor racers to ensure that competitors have enough water and food and that no one is hurt. If an official thinks a racer cannot compete the race because of injury, the racer will be removed from the race. Checkpoints during the cell cycle have a similar function. Special proteins at these checkpoints monitor cell activities and send this information to the nucleus. The nucleus then instructs the cell whether or not to divide. Cellsb will not divide if: - There are not enough nutrients to support cell growth. - DNA within the nucleus has not been replicated. - DNA ia damaged. Overall, it could create some uncontrolled cell division and mutations which could create huge problems.
Yes, mutations are passed on to new cells during replication. If a mutation occurs in a cell's DNA, it will be present in all daughter cells that are produced through replication. This can lead to genetic variation and evolution over time.
So that the genes can be passed on.

More DNA which can be passed on to the resultant cells of mitosis.
Segregation ended after Brown vs. Board of education was passed, when MLK made his speech, when the jim crow laws were killed, etc. There are many different checkpoints, but there was never a specific date of the end.

Replication refers to the process of copying genetic material, such as DNA or RNA, to produce an exact replica of the original molecule. In the context of biology, replication is a fundamental process that ensures genetic information is accurately passed on to daughter cells during cell division.
No, chlamydia cannot be passed from cats to humans.
Cell cycle checkpoints are used by the cell to monitor and regulate the progress of the cell cycle. Checkpoints prevent cell cycle progression at specific points, allowing verification of necessary phase processes and repair of DNA damage. The cell cannot proceed to the next phase until checkpoint requirements have been met. Several checkpoints are designed to ensure that damaged or incomplete DNA is not passed on to daughter cells. Two main checkpoints exist: the G1/S checkpoint and the G2/M checkpoint. G1/S transition is a rate-limiting step in the cell cycle and is also known as restriction point. An alternative model of the cell cycle response to DNA damage has also been proposed, known as the postreplication checkpoint. p53 plays an important role in triggering the control mechanisms at both G1/S and G2/M checkpoints. Impaired spindle checkpoint function has been found in many forms of cancer. The BRCA1 tumor suppressor plays a role in the activation of human chk1, therefore the posreplication checkpoint may prevent the genetic changes that lead to cancer. Mutations in factors contributing to cell cycle arrest at the restriction point are thought to be the main contributors of cancer. hope this helps!
