41. C.DNA is made up of proteins, which tells a cell how to function
42. <span>C. So they can move materials from one area of the cell to another quickly
A DNA is made of proteins which was synthesized by ribosomes of the cell to produce protein and these proteins are churned into mRNA and then these mRNA and used to catalyse the DNA production. DNA of a cell in the nucleus is the programmed individuality that controls, manages and organises the entire cell to function and initiate cellular activities.
It is more efficient, thus, to move materials quickly.

I am an online student, this was a question on my quiz and I got it right.
You're welcome.

Answer:
G1 checkpoint
Explanation:
The cell cycle consists of the series of activities that occurs from the replication of DNA to the actual division of the cell in an organism's cell. However, the cell has been internally programmed to ensure that all conditions are in place/favorable before allowing progression into the next stage of the cell cycle. This internally controlled mechanism ia called CHECKPOINTS. This checkpoint occurs at three main stages of the cell cycle;
after G1 phase, G2 phase and during M phase.
In the G1 checkpoint, the cell ensures that the cell is in the right shape to proceed into the Synthesis phase of the cell cycle where it will double it's DNA. The checkpoint checks majorly for damage or change to the DNA before replicating it. If any error is found, that cell is halted and prevented from proceeding to the S-phase of the cell cycle.
This is the case in the question, the cell has been halted and prevented from entering the S-phase. Hence, its DNA is still the same as it started. However, the DNA of the cells surrounding it has been doubled as they have undergone DNA replication during S-phase.
A psychological disorder or a mental disorder is compose of behavioral and psychological symptoms impacting on areas of one's life causing further problems. When a psychiatrist like Dylan works on the causes of the disorder such as chemical imbalances, he is now working on the Biological perspective of the treatment.
