Question

14- properly draw and label a chromosome and its parts on the space provided.

1. one half of a duplicated chromatid

Explanation:

A typical replicated chromosome (metaphase stage) has the following key parts to draw and label:

1. Sister Chromatids: Two identical, rod-shaped structures making up the duplicated chromosome.
2. Centromere: The constricted region that holds the sister chromatids together.
3. Short Arm (p arm): The shorter segment of each chromatid extending from the centromere.
4. Long Arm (q arm): The longer segment of each chromatid extending from the centromere.
5. Telomeres: The protective, repetitive DNA sequences at the very ends of each chromatid arm.

Answer:

A labeled chromosome diagram should include:

• Two parallel sister chromatids connected at a central centromere
• Labeled short (p) and long (q) arms on each chromatid
• Labeled telomeres at the tips of all chromatid arms
