Bio 9.2 and 3 Flashcard

Front

What is the phase of cell division in which chromatin condenses into chromosomes?

Back

Prophase

Front

What structures are lined up at the center of a cell during metaphase?

Back

Chromosomes

Front

What are the functions of cyclin and cyclin-dependent kinases in the cell cycle?

Back

They regulate the progression of the cell cycle by activating cyclin-dependent kinases (CDKs) that phosphorylate target proteins.

Front

What are substances known to cause cancer called?

Back

Carcinogens

Front

What does the spindle apparatus contain?

Back

Spindle fibers, centrioles, and aster fibers.

Front

What is the role of spindle fibers during cell division?

Back

They help separate chromosomes during anaphase.

Front

What is the significance of cyclins in the cell cycle?

Back

Cyclins are proteins that regulate the timing of the cell cycle in eukaryotic cells.

Front

What is the difference between chromatin and chromosomes?

Back

Chromatin is the relaxed form of DNA found in the nucleus, while chromosomes are the condensed form of DNA that is visible during cell division.

Front

What is the function of centrioles in cell division?

Back

Centrioles help organize the mitotic spindle and are involved in the formation of cilia and flagella.

Front

What is the purpose of the aster fibers during mitosis?

Back

Aster fibers help anchor the spindle apparatus to the cell membrane.
