What is a ligand?
A molecule that binds to a specific site on a target protein, often resulting in a conformational change that can influence the protein's activity and function.
How can a mutation lead to cancer?
By causing a halt in the G2 checkpoint or stopping cyclin receptors.
Where does a signal need to reach to be expressed as protein?
The nucleus, which stores information to make protein.
What is the difference between chromatid and chromatin?
Chromatid refers to one half of a duplicated chromosome, while chromatin is uncondensed DNA.
What type of signaling occurs if a ligand is connected to a membrane?
Long-distance signaling protein. because the ligand directly interacts with a receptor on an adjacent cell through cell-to-cell contact (ligand=long)
Why is the S phase important?
Because it is the stage of DNA replication where 2n turns into 4n.
What is cancer?
A mutation that causes a cell to spend too much time in mitosis, leading to uncontrolled mitosis.
