Question

1. what stage of the cell cycle is responsible for cell growth? a) g2 phase b) interphase c) s phase d) g1 phase 9. which of the following cell - cycle descriptions is correct? a) chromosomes are replicated during the g1 phase b) interphase is when the cell spends most of its time performing its cell function c) the s phase consists of prophase, metaphase, anaphase, and telophase d) mitosis phase 10. which of the following is incorrect? a) g1 phase is responsible for cell growth b) g2 phase is responsible for preparation for mitosis c) m stage is for cell division d) s phase is for cell growth

Explanation:

1. The G1 phase is when the cell grows in size, synthesizes proteins and organelles, and performs its normal metabolic functions. It is the primary phase for cell - growth in the cell cycle.
2. During the S phase, DNA replication occurs. Chromosomes are replicated during this phase. Interphase is the part of the cell cycle where the cell spends most of its time performing normal cell functions, and it includes G1, S, and G2 phases. Mitosis consists of prophase, metaphase, anaphase, and telophase.
3. The G2 phase is responsible for preparing for mitosis. It synthesizes proteins needed for cell division and checks for DNA damage. The M phase is for cell division. The S phase is for DNA replication, not cell - growth. The G1 phase is for cell - growth, not preparation for mitosis.

Answer:

1. a. G1 phase
2. b. Chromosomes are replicated during the S phase
3. c. G2 phase is responsible for preparation for mitosis
