Answer:
Colchicine inhibits the formation of microtubules by inhibiting tubulin, a protein required for microtubule synthesis. Microtubules in the form of spindle fibers during cell division pull the DNA from the center of the mother cell into the new daughter cells. If microtubules are not formed DNA will not move into new cells. Hence new cell formation will be inhibited in the metaphase stage. Thus the correct answer is option D.

Answer- cell X
Explanation- prokaryotes doesn’t have a Nucleus nor chloroplasts
Answer: Very unlikely
Explanation:
Generally, point mutation can be easily reversed by another point mutation, so
before any changes occur in the amino acid sequence, it would have been corrected.
However, when point mutation occurs within the protein coding region of a gene it may results in the change of a single nucleotide to cause the substitution of a different amino acid (which renders the protein non-functional) as in the case of sickle-cell disease.
And this kind of point mutation is specifically called Missense mutation.
Above all, because point mutation is easily reversible, it is very unlikely to change the amino acid sequence of a protein
Answer: C.) Leaf
Explanation: Leaves are the main sites for photosynthesis which is the process by which plants that synthesize food. Most leaves are usually green, due to the presence of chlorophyll in the leaf cells.
