Answer:
Interphase (Synthesis stage)
Explanation:
Before a cell can undergo division (mitosis), it must first make a copy of its genetic material which each daughter cell will have. This process of DNA replication takes most of the time of the cell cycle, making the interphase, specifically the S phase, the longest phase of the cell cycle. The interphase stage occurs in three steps:
1. G1 phase: This is also called the first gap phase. The cell is biochemically active at this stage, hence it grows physically larger and makes copies of its organelle. The cell also accumulates building blocks of DNA molecules.
2. S phase: Also called Synthesis phase, the cell makes a copy of its DNA in its nucleus. DNA material (uncoiled chromatin) is replicated into two identical pairs. The centrosomes, which gives rise to the mitotic spindle, is also replicated. These spindles separate the sister chromatids during mitosis.
3. G2 phase: This is also called the second gap phase. It is the last step of interphase before mitosis begins. The cell makes protein and prepared for mitosis by rearranging its contents. It ends when mitosis begins.
Pollination is a reproduction process foundi in plants where the pollen of one flower is transferred to another flower.
In a more detailed explanation, pollination is a process in which pollinators are protagonists. These (normally insects) go from flower to flower collecting nectar, and during that collection, pollen sticks on to them, and then falls in another flowers interior.
What is pollen?
Pollen are fine particles, of something you might call "dust", produced by the male organs in a plants flower.

Answer:
Involve changes in one or few nucleotides/ bases
Explanation:
Point mutations most commonly involve the substitution of one base for another (which changes the complementary base as well in DNA). The term point mutationt also includes insertions or deletions of a single base pair.
