Question

one difference between a cancer cell and a normal cell is that
cancer cells cannot make copies of dna
cancer cells divide uncontrollably
normal cells cannot make copies of dna
normal cells divide uncontrollably
what specific stage is dna replicated?
g1 phase of interphase
anaphase of mitosis
s stage of interphase
s stage of mitosis
prophase of mitosis

Explanation:

• For the first question: Cancer cells have the characteristic of uncontrolled division. Normal cells have regulated division processes. Both cancer and normal cells can make copies of DNA (as they need to replicate for cell division).
• For the second question: DNA replication occurs in the S (synthesis) stage of interphase. In the G1 phase of interphase, the cell grows and prepares for DNA replication. In mitosis (prophase, anaphase etc.), the focus is on cell division (like chromosome separation in anaphase) not DNA replication. There is no S stage of mitosis.

Answer:

• First question: Cancer cells divide uncontrollably
• Second question: S stage of interphase
