chromosomes
Genes that encourage cell division are typically referred to as proto-oncogenes. These genes promote normal cell growth and division by producing proteins that drive the cell cycle and facilitate cellular proliferation. When proto-oncogenes undergo mutations or are overexpressed, they can become oncogenes, potentially leading to uncontrolled cell division and cancer development.
Genes such as cyclins, cyclin-dependent kinases (CDKs), and tumor suppressor genes like p53 play essential roles in regulating the proteins necessary for cell division. These genes ensure that the cell cycle progresses accurately by controlling checkpoints and cell division processes. Mutations in these genes can lead to uncontrolled cell division and contribute to conditions like cancer.
Cell division is primarily controlled by genes that encode various proteins, including cyclins and cyclin-dependent kinases (CDKs), which regulate the cell cycle. DNA polymerase plays a critical role in DNA replication during cell division but does not directly control the process itself. Instead, it is the interactions and activities of these proteins, guided by the genetic information in DNA, that orchestrate the complex regulatory mechanisms of cell division. Thus, genes and their protein products are key regulators in this process.
Abnormalities in genes that control cell growth and division, such as mutations, can cause a cell to divide out of control. This uncontrolled division can lead to the formation of a tumor.
Chromosomes contain genes, which are sequences of DNA that provide instructions for making proteins. These proteins are essential for controlling and participating in various cell processes, such as cell division, growth, and metabolism. When a cell needs to carry out a specific process, it can activate the genes on its chromosomes to produce the necessary proteins.

when cell division occurs chromosomes segregate & also the genes present in pairs on then as the genes store genetic information it is kept constant though cell division
Your question is not clear. If you meant to ask, "Do chromosomes and genes remain the same in the original cell? (i.e. after cell division)" then yes.
proto-oncogenes
Genes called proto-oncogenes stop a cell from dividing too often.

The two types of cell cycle genes that, when mutated, can lead to uncontrolled cell division and cancer are oncogenes and tumor suppressor genes. Oncogenes promote cell division and growth; mutations can lead to their overactivity, driving excessive proliferation. In contrast, tumor suppressor genes normally inhibit cell division or promote apoptosis; mutations can inactivate these protective functions, allowing unchecked cellular growth. Both types of mutations disrupt the delicate balance of cell cycle regulation, contributing to cancer development.
Disruptions in the cell cycle can lead to uncontrolled cell division, which is a hallmark of cancer. Mutations in genes regulating the cell cycle, such as tumor suppressor genes or oncogenes, can promote the growth of cancer cells. This uncontrolled division allows cells to accumulate additional mutations that can lead to tumor formation and cancer development.
