Multiple Choice
Which of the following is true of kinetochores during cell division?
A
Kinetochores are involved in the synthesis of proteins.
B
Kinetochores are the sites where spindle fibers attach to chromosomes.
C
Kinetochores are responsible for the replication of DNA.
D
Kinetochores are the structures that form the nuclear envelope.
Verified step by step guidance1
Understand the role of kinetochores in cell division: Kinetochores are protein structures located at the centromere of each chromosome.
Recognize the function of kinetochores: They serve as attachment points for spindle fibers during mitosis and meiosis.
Differentiate kinetochores from other cellular components: Kinetochores do not synthesize proteins, replicate DNA, or form the nuclear envelope.
Identify the correct statement: Kinetochores are crucial for the movement and segregation of chromosomes by connecting them to the spindle apparatus.
Conclude that the correct answer is: Kinetochores are the sites where spindle fibers attach to chromosomes.
