Fruit fly body cells have 8 chromosomes. After mitosis, you would expect a resulting fruit fly daughter cell to have ...

8 chromosomes.

Answer explanation

After mitosis, the number of chromosomes in daughter cells remains the same as in the parent cell. Since fruit fly body cells have 8 chromosomes, each daughter cell will also have 8 chromosomes.

FLASHCARD QUESTION

Front

Structure (a) is a ____.

Media Image

Back

chromosome

Answer explanation

Structure (a) is a chromosome because it represents a complete DNA molecule that contains genetic information. Chromatids are the duplicated forms of a chromosome, and a centromere is the region where two chromatids are joined.

Back

centromere

Answer explanation

Structure (b) is a centromere, which is the region of a chromosome where the two sister chromatids are joined. It plays a crucial role during cell division, ensuring proper segregation of chromosomes.

Back

chromatid

Answer explanation

Structure (c) is a chromatid because it represents one half of a duplicated chromosome, which is connected at the centromere. Chromatids are formed during the S phase of the cell cycle when DNA is replicated.

Anaphase

Answer explanation

Anaphase is the phase where sister chromatids are pulled apart to opposite poles of the cell. This distinguishes it from the other phases, where chromosomes are aligned or the cell is preparing to divide.

FLASHCARD QUESTION

Front

What is the next phase of mitosis?

Back

Telophase

Answer explanation

The next phase of mitosis after anaphase is telophase. During telophase, the chromosomes begin to de-condense, and the nuclear envelope re-forms, leading to the final stages of cell division.
