What are specialized proteins that both regulate the cell cycle and cause it to occur?
Proteins called internal regulators and external regulators control the cell cycle. Internal regulatory proteins allow the cell cycle to proceed only when certain events have occurred in the cell itself. External regulatory proteins direct cells to speed up or slow down the cell cycle.
What are the 3 things that regulate the cell cycle?
Cyclins and regulatory proteins. Regulatory proteins include internal regulators and external regulators
What is the internal regulatory proteins effect?
mitoconderia
What does it mean when a cell enters anaphase before all of its chromosomes have attached to the spindle?
This indicates that the cell is not responding to the internal regulators inside the cell.
Which does not control the cell cycle?
The cell cycle is controlled by specific cyclins, which are proteins that regulate the cell cycle.
In the cell cycle external regulators direct cells to?
speed up or slow down the Cell Cycle
What are the two types of regulators in the cell cycle?
Meiosis: Meiosis produces daughter cells that have one half the number of chromosomes as the parent cell. (Also the sexual cell cycle that requires to different cells) Mitosis: Mitosis produces two daughter cells that are identical to the parent cell. (Also the asexual cell cycle that requires only the one parent cell)
How do external regulators respond to events outside the cell?
External regulators direct cells to speed up or slow down the cell cycle.
How is the cell cycle regulated?
By injecting a protein found from a cell in mitosis into a non-dividing cell, a mitotic spindle forms. The protein was later called cyclin. Cyclins regulate the timing of the cell cycle.

What are internal regulate?
Internal Regulators Proteins that respond to events inside the cell are called internal regulators. Internal regulators allow the cell cycle to proceed only when certain processes have happened inside the cell. For example, several regulatory proteins make sure that a cell does not enter mitosis until all its chromosomes have been replicated. Another regulatory protein prevents a cell from entering anaphase until all its chromosomes are attached to the mitotic spindle.

Internal regulators are proteins that respond to activity within a cell.
What arte the 3 things that regulate the cell cycle?
The 3 things are cyclins, internal regulators, and external regulators. I'm not sure though thats what it says in my bio book...
What are external regulators?
External regulators are proteins that respond to events outside the cell. These proteins direct cells to speed up or slow down the cell cycle, like traffic lights. For example, growth factors are one of the most important external regulators, and they stimulate the growth and division of cells. These differ from internal regulators in the fact that they respond to events inside the cell. Internal regulators allow the cell to proceed only when certain processes have happened inside the cell. Hope this helps! : )

What has the author Eric Marmor written?
Eric Marmor has written: 'The role of cell cycle regulators P53 and P161INK4A in the pathogenesis of primary brain tumours'
What is the internal regulatory proteins effect?
mitoconderia
What is the importance of internal regulators in a cell?
it does stuffage
