At the DNA synthesis G2 checkpoint DNA replication is checked by 1 receptor proteins 2 Repair enzymes 3 electron transport chains 4 cell surface markers?
2 Repair enzymes. At the DNA synthesis G2 checkpoint, DNA replication is checked by repair enzymes that detect and repair any mistakes in the replicated DNA before the cell progresses to mitosis. Receptor proteins, electron transport chains, and cell surface markers are not directly involved in checking DNA replication at this checkpoint.
What are the three checkpoints where the cell divides?
The three checkpoints are...G1 (restriction) checkpoint: where the decision is made whether the cell will be divided, delayed division or enter the resting stageG2 checkpoint: which checks the success of DNA replication from the S phaseM checkpoint: the process of mitosis is assessed (whether it was a success)If at any time the cell doesn't pass the checkpoints, the cells stops and repairs so that it can continue along the cell cycle.
How many sets of instructions are there in the nucleus of an egg cell or sperm cell?
There is only one set of instructions in the nucleus of an egg cell or a sperm cell. This set of instructions contains the genetic information necessary for the development of a new organism if fertilization occurs.
Substances that can pass through cell membranes by diffusion include?
Small molecules such as oxygen, carbon dioxide, and water can pass through cell membranes by diffusion. Lipid-soluble molecules like alcohol and steroid hormones can also diffuse through cell membranes.
Through how many heart valves must a blood cell pass as it moves from the brain to the lungs?
A blood cell must pass through two heart valves to travel from the brain to the lungs. As it exits the brain through the superior vena cava, it passes through the tricuspid valve, then through the pulmonary valve to reach the lungs for oxygenation.
Before a cell can proceed to mitosis from the gap 2 stage of the cell cycle it must?
Undergo a series of checkpoints, including checking for DNA damage and ensuring that the cell has replicated its DNA correctly. If the checkpoints are passed, the cell will proceed to mitosis. If issues are detected, the cell may pause for repair or undergo programmed cell death.
What is the checkpoint?

In free rider 2 how do you place a checkpoint in a track?
When you select your checkpoint, simply just click where you want to add it.

Is it necessary to Unplug cell phone before answering?
NO you do not have 2 unplug a cell phone b4 answering it
How many phases are there in the eukaryotic cell cycle?
Cell cycle is defined as sequence of event between one cell division and the next . In eukaryotic , have 4 phase of cell cycle . 1. G1 - increase size, produce RNA, synthesis protein . - checkpoint to prepare enter S phase. 2. S phase - DNA replication. 3. G2 - contineu increase in size and produce protein. - Checkpoint to determine if cell can enter mitotic phase. 4. Mitotic phase - mitosis + cytokinesis
How do you respawnorama in Achievement Unlocked 2?
Respawn at every checkpoint.

How do you go to a special stage on sonic 2?

Is there a certain amount of time that mushers have to stay at a checkpoint?
yes. example: every musher in the iditarod race can spend 24 hours only once at a checkpoint. so it would be a good idea when they are tired to stop at a checkpoint for 24 hours since they only get to do it once. they all have limited time at checkpoint. if u r confused, go 2 the iditarod website.
