telophase
telophase

what happens to a cell prior to metaphase in mitosis?

the chromosomes lined up in the middle and started separating
the dna wouldve been replicated chromosomes separated
the dna wouldve been replicated, chromosomes formed, and the nuclear membrane broken down
the nuclear membrane re-forms and the chromosomes triple in size

Explanation:

Analyze Question 39

Using the Mitosis Stages and Cell Cycle Phases knowledge points

• Anaphase is the specific stage of mitosis where sister chromatids (referred to as chromosomes once separated) are pulled apart by spindle fibers toward opposite poles of the cell.
• Interphase is the preparatory phase before division.
• Telophase is the final stage where nuclei reform around the separated chromosomes.

Analyze Question 40

Using the Mitosis Stages and Cell Cycle Phases knowledge points

• Prior to metaphase, the cell must complete interphase (specifically S phase for DNA replication) and prophase (where chromatin condenses into visible chromosomes and the nuclear envelope breaks down).
• The option "the DNA would've been replicated, chromosomes formed, and the nuclear membrane broken down" accurately summarizes these pre-metaphase events.

Answer:

Question 39

• interphase
• anaphase (Correct answer)
• telophase
• telophase

Question 40

• the chromosomes lined up in the middle and started separating
• the DNA would've been replicated chromosomes separated
• the DNA would've been replicated, chromosomes formed, and the nuclear membrane broken down (Correct answer)
• the nuclear membrane re-forms and the chromosomes triple in size
