Students were asked over to answer a question at school and to claim what is most important for them to succeed. Out of the many responses, one which that stood out was practice. Persons who usually are successful do not become successful by being born. They work hard and dedication their lives to succeeding. This is how you can complete your goals. just below some question and answer examples that you might possibly benefit from to supercharge your knowledge and gain insight that will guide you to sustain your school studies.
Match each checkpoint with the action it checks for. Checks whether the microtubules have attached to the centromeres of the chromosomes checks for cell size and DNA damage checks whether DNA has doubled and repairs it if damaged
The cell cycle is mainly regulated with the help of three checkpoints: G₁ checkpoint, G₂ checkpoint, and M checkpoint.
G₁ checkpoint checks for
- Size of the cell
- Nutritional availability
- Growth factors and
- DNA (deoxyribonucleic acid) damage.
Hence, it can be correctly matched with checks for cell size and DNA damage.
Only after passing through this check point the cell enters the S or synthesis phase where the DNA content is doubled.
The G₂ checkpoint is present between G₂ phase and M phase. It checks the cell for its protein reserves as well as if the DNA has replicated accurately or not.
If cell passes this checkpoint then it enters into the M phase.
Hence, it can be correctly matched with checks whether DNA has doubled and repairs it if damaged
Lastly, the M checkpoint checks if spindle microtubules are properly attached to the centromeres of all the chromosomes.
This checkpoint allows the progression from metaphase to anaphase.
Hence, it can be correctly matched with microtubules have attached to the centromeres of the chromosomes.
They can easily hopefully assist the student answer the question by make use of the questions and answer examples. You could potentially then have a discussion with your classmate and continue the school learning by studying the topic together.
