chromosomes
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.
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.
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.
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.
Genes that are located on the same chromosome are called linked genes. These genes tend to be inherited together during cell division because they are physically close to each other on the same chromosome.

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
proto-oncogenes
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.
Genes called proto-oncogenes stop a cell from dividing too often.

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.
Genes are composed of DNA. DNA bear the the information to guide he gene. Gene codes for proteins and maintain whole body. From the embryo the cell division depends on the enzyme that is encoded by the genes. Of the genes half is from father and half is from mother.
· 1) Genes involved in cell division · 2) Oncogenes o Dominant-acting stimulatory genes o Normally low levels or expression is turned off o Mutation causes increased/hyper expression · 3) Tumour suppressor genes o Recessive-acting genes o Normally expressed to inhibit cell division o Mutation causes defects in product or no expression
