What happens during anaphase of mitosis?

Back

Paired chromatids will separate, and the new daughter chromosomes will move toward opposite poles of the cell.

Front

What are plasmodesmata?

Back

Direct contact communication channels between plant cells that allow for the transport of materials and signaling.

Front

What is the purpose of phosphorylation cascades in cellular signaling?

Back

They are often used for amplification of the signal within the cell.

Front

What type of signaling occurs in synaptic signaling?

Back

Local signaling where neurotransmitters are released from one neuron to affect another neuron.

Front

Which graph represents DNA content throughout the cell cycle?

Back

Graph B represents the amount of DNA present in a normal cell throughout the cell cycle.

Front

What is the role of kinetochores during cell division?

Back

Kinetochores are protein structures on chromatids where the spindle fibers attach to pull chromatids apart.

Front

Define interphase in the cell cycle.

Back

Interphase is the phase of the cell cycle where the cell prepares for division, including DNA replication.

Front

What is the function of the nuclear envelope during mitosis?

Back

The nuclear envelope breaks down to allow the chromosomes to be separated during cell division.

Front

What is the difference between local signaling and long-distance signaling?

Back

Local signaling occurs between nearby cells, while long-distance signaling involves hormones traveling through the bloodstream.

Front

What are gap junctions?

Back

Gap junctions are specialized intercellular connections that allow direct communication between animal cells.
