Question

parts of the sphenoid bone include the ________.zygomatic processsquamous portionglabellasella turcicaquestion 162 ptsduring what phase of the cell cycle does dna replication occur?s phaseprophase of mitosismitosisg2 phase

Explanation:

• For the first question:
• The sphenoid bone has a sella turcica which is a saddle - shaped depression that houses the pituitary gland.
• The zygomatic process is part of the temporal bone.
• The squamous portion is part of the temporal bone.
• The glabella is part of the frontal bone.
• For the second question:
• DNA replication occurs during the S (synthesis) phase of the cell cycle.
• Prophase of mitosis is the first stage of mitosis where chromatin condenses, not a time for DNA replication.
• Mitosis is the process of cell division (nuclear division) and not the phase for DNA replication.
• The G2 phase is a gap phase after DNA replication where the cell prepares for mitosis.

Answer:

• First question: sella turcica
• Second question: S phase
