Cancer is fundamentally a disease of genes, as it arises from mutations in the DNA that alter normal cell function. These genetic changes can lead to uncontrolled cell growth and division, which are hallmarks of cancer. While environmental factors and lifestyle choices can influence these genetic changes, the underlying mechanisms of cancer are rooted in the genetic alterations that affect cellular behavior. Hence, it can be said that cancer is a disease of both genes and DNA, as the mutations in DNA within genes drive the disease.

A disease caused by a mutation in genes that control the cell cycle?
Cancer is a disease caused by mutations in genes that regulate the cell cycle, leading to uncontrolled cell growth and proliferation. These mutations can disrupt the normal processes that control cell division and growth, allowing cancer cells to multiply uncontrollably and form tumors.
What is the relationship between chromosomes and genes and between genes and DNA?
Chromosomes are structures made of DNA that carry genes. Genes are segments of DNA that contain the instructions for making proteins. DNA is the molecule that carries the genetic information needed for the development, functioning, and reproduction of living organisms.
Are genes and proteins both made of DNA?
Genes are the units of heredity, and are made up of segments of DNA
What is the primary cell structure that when damaged starts the process of cancer formation?
The primary cell structure involved in the initiation of cancer formation is the DNA within the cell nucleus. When DNA is damaged due to factors like radiation, chemical exposure, or replication errors, it can lead to mutations. If these mutations affect genes that regulate cell growth and division, such as oncogenes or tumor suppressor genes, it can result in uncontrolled cell proliferation and tumor formation. Thus, DNA integrity is crucial for preventing cancer development.
How are genes are protein related?
Genes are made up of DNA. DNA have codes to form proteins
Cancer is a disease of which of these?
Genes
Cancer is a disease of which of these genes DNA hormones?
Cancer emerges by DNA mutations. DNA = genes. The mutations lead to protein aberations in the cell. But, some proteins are hormones as well and some of these can cause cancer. To summarize it, let's say that cancer is a disease of genes and DNA in 95% cases and cancer is a disease of hormons in 5% cases. (very roughly, but it is true)
What type of disease is cancer?
Genes on A+
How does chemestry affect cancer?
Chemicals that do not cause cancer by themselves but can act with another chemical to cause cancer (cocarcinogens). Damage to DNA in cells can lead to cancer. ... Unrepaired DNA damage can lead to mutations, or changes, in genes, and mutations in certain genes can cause cancer. You can also inherit mutations.
Are genes in DNA or are DNA in geans?
genes are in DNA
What does BRCA mean?
BRCA1 and BRCA2 are two genes in your DNA which when altered or mutated, leads to Breast cancer.
A disease caused by a mutation in genes that control the cell cycle?
Cancer is a disease caused by mutations in genes that regulate the cell cycle, leading to uncontrolled cell growth and proliferation. These mutations can disrupt the normal processes that control cell division and growth, allowing cancer cells to multiply uncontrollably and form tumors.
How do tumor suppressor genes work to prevent the development of cancer?
Tumor suppressor genes help prevent cancer by regulating cell growth and division. They can repair damaged DNA, trigger cell death, or stop cells from dividing uncontrollably. When these genes are mutated or inactive, cells can grow out of control, leading to the development of cancer.
What do DNA Profiling and Captive Breeding programs to help Tasmanian Devils?
DNA profiling can help determine the particular genes which are active in the deadly cancer cells. This inturn can help scientist find a cure for the disease. Captive breeding ensure that there are a population of healthy devils which can be sustainably released into the wild.
What is the relationship between chromosomes and genes and between genes and DNA?
Chromosomes are structures made of DNA that carry genes. Genes are segments of DNA that contain the instructions for making proteins. DNA is the molecule that carries the genetic information needed for the development, functioning, and reproduction of living organisms.
How much of your DNA contains genes?
20.3% of your DNA contains genes
Cancer can be caused by changes in this?
Cancer can be caused by changes in the DNA of cells. The development of cancer is often associated with genetic mutations or alterations in the DNA sequence of certain genes. These changes can disrupt the normal regulatory mechanisms that control cell growth, division, and death. The key factors related to cancer development include: Genetic Mutations: Mutations in specific genes can lead to uncontrolled cell growth and the formation of tumors. Mutations can be inherited (germline mutations) or acquired during a person's lifetime (somatic mutations). Oncogenes: Oncogenes are normal genes that, when mutated or activated, can promote the development of cancer. These genes are involved in regulating cell growth and division. Tumor Suppressor Genes: Tumor suppressor genes normally prevent the uncontrolled growth of cells. Mutations that inactivate these genes can contribute to cancer by allowing cells to evade normal growth controls. DNA Repair Genes: DNA repair genes are responsible for fixing errors or damage in the DNA sequence. Mutations in these genes can lead to the accumulation of genetic abnormalities and an increased risk of cancer. Epigenetic Changes: Epigenetic modifications, such as alterations in DNA methylation or histone modifications, can influence gene expression without changing the underlying DNA sequence. Abnormal epigenetic changes can contribute to cancer development. Environmental Factors: Exposure to certain environmental factors, such as tobacco smoke, ultraviolet (UV) radiation, certain chemicals, and infectious agents, can cause DNA damage and increase the risk of cancer. Lifestyle Factors: Unhealthy lifestyle choices, including poor diet, lack of physical activity, and excessive alcohol consumption, can contribute to DNA damage and increase susceptibility to cancer. Heredity: Inherited genetic mutations passed down from one generation to the next can increase the risk of certain cancers. However, most cancers are not directly inherited but result from a combination of genetic and environmental factors. Understanding the genetic and molecular changes associated with cancer is crucial for developing targeted therapies and personalized treatment approaches. Early detection and intervention are also essential for improving outcomes in cancer patients.
