Answer: DNA is kind of like the "blueprint" for the creation of a protein. It holds all the information for the making of a protein cell
Explanation: mRNA is a copy of the DNA and this copy then leaves the nucleus, into the cytoplasm, and to the ribosomes where the mRNA is then translated by tRNA codons to turn it into amino acids, and these amino acids are then raveled up into a protein cell. You can't have a protein cell without your DNA.

Answer:
The correct answer will be option-A
Explanation:
Colchicine is the drug that prevents the assembly of the mitotic spindles which halts or stops the cell cycle.
The colchicine acts by inhibiting the microtubule polymerization thus mitotic spindles which takes place after the condensation of the chromosomes during prophase and pre-metaphase.
This acts as checkpoint which can halt the cell cycle at the phase of chromosome condensation.
Thus, option-A is the correct answer.
