The mass of an atom is contained in the nucleus.
Answer:
It would alter ecosystems.
Explanation:
If ice were to sink and liquid water were to float on top of ice, then that means that all ice would deposit at the bottom of the ocean. This means that the temperatures of all oceans would be reduced significantly. If this is the case, then marine biology would look very different than it normally looks today. Also, because there is a theory that life originated from microorganims in underwater volcanoes, we have to realize that It would have made life much more complex.
p16 is a tumour suppressor protein that functions as a cyclin-dependent kinase inhibitor and is required for cell cycle regulation. Because p16 inhibits cyclin-dependent kinases that phosphorylate Rb, it can slow down the cell cycle.
<h3>Tumor suppressor genes encode which type?</h3>
Tumor suppressor genes, also known as anti-oncogenes, encode proteins that transduce negative cell growth regulatory signals such cell cycle arrest and death.
The TP53 gene codes for the production of a protein known as tumour protein p53 (or p53). This protein functions as a tumour suppressor, which means it controls cell division by preventing cells from growing and dividing (proliferating) too quickly or uncontrollably.
Cyclins and cyclin-dependent kinases are two types of proteins that promote the cell cycle.
