Question

why is g1 important?
without this process, youd end up with two tiny and ineffective cells.
without this process, new cells would not have their own copy of dna.
without this process, cells would never completely divide into two cells.
without this process, cells would never stop dividing.

Explanation:

G1 is a phase in the cell cycle where the cell grows in size, synthesizes proteins and organelles. If a cell skips G1, it won't grow properly. When cell division occurs (like in mitosis), without proper growth in G1, the two daughter cells would be tiny (due to lack of growth) and might not function effectively (as they lack sufficient cellular components for normal cell - related processes).

• The second option is about DNA copying which occurs in S - phase.
• The third option about complete division is related to cytokinesis.
• The fourth option about stopping division is related to cell - cycle checkpoints (not specifically G1 function in terms of cell size for division outcome).

Answer:

Without this process, you'd end up with two tiny and ineffective cells.
