What else can I help you with?
Is mutations that occur in body cells will always be threatening to the organism?
yes, true.
How radiation effect normal cell?
Radiation can damage normal cells by causing breaks in DNA strands or creating free radicals that lead to cellular dysfunction. This can result in cell death or mutations that may lead to cancer. Normal cells can often repair some of the damage caused by radiation, but high doses or prolonged exposure can overwhelm the repair mechanisms, causing harm.
What do you call genes that encode proteins that are always needed?
Genes that encode proteins that are always needed are called housekeeping genes. These genes are essential for basic cellular functions and are expressed in all cells and tissues to maintain normal cellular activities.
Why aren't somatic mutations passed on to the next generation?
Somatic mutations occur in non-reproductive cells and are not passed on to offspring because they do not affect the germline cells (sperm and eggs) that give rise to the next generation. Only mutations in the germline cells can be inherited by offspring.
How mutations in reproductive cells are different from mutations in body cells?
Mutations in reproductive cells can be passed on to offspring, potentially impacting future generations, while mutations in body cells typically affect only the individual in which they occur. Reproductive cell mutations can lead to genetic disorders in offspring, while mutations in body cells may cause diseases or cancer in the individual.
What is the relationship between carcinogens and mutations?
Carcinogens are substances that can cause mutations in the DNA of cells, which can lead to the development of cancer. Mutations are changes in the genetic material of cells, and when these mutations are caused by carcinogens, they can disrupt the normal functioning of cells and potentially lead to uncontrolled cell growth and the formation of tumors.
Why is ionisation dangerous to your cells?
Ionization can lead to the formation of free radicals, which are highly reactive and can damage cellular components such as DNA, proteins, and cell membranes. This damage can disrupt normal cellular functions and lead to mutations, cell death, or even cancer.
How the presence of a cancerous tumor affect the biological processes?
Cancerous tumours are formed from cells which have had mutations in very specific genes which have allowed them to survive independantly of cells around them in the body. Some of these key genes code for growth factors and other proteins which affect normal body cells. Often the tumour cell mutations cause upregulation of these growth factors causing neighbouring healthy cells to be affected in unusual ways.
Is mutations that occur in body cells will always be threatening to the organism?
yes, true.
How do mutations impact protein synthesis?
Mutations can affect protein synthesis by changing the sequence of DNA, which can lead to errors in the production of proteins. This can result in altered or non-functional proteins being made, which can impact the overall functioning of cells and organisms.
Mutations in body cells can sometimes result in?
Mutations in body cells can sometimes result in cancer, a condition where cells grow and divide uncontrollably. Mutations can also lead to genetic disorders, affecting the normal functioning of cells and tissues.
How radiation effect normal cell?
Radiation can damage normal cells by causing breaks in DNA strands or creating free radicals that lead to cellular dysfunction. This can result in cell death or mutations that may lead to cancer. Normal cells can often repair some of the damage caused by radiation, but high doses or prolonged exposure can overwhelm the repair mechanisms, causing harm.

Genes that encode proteins that are always needed are called housekeeping genes. These genes are essential for basic cellular functions and are expressed in all cells and tissues to maintain normal cellular activities.
What is the relationship between carcinogens and mutations, and how do they contribute to the development of cancer?
Carcinogens are substances that can cause mutations in our DNA, which are changes in the genetic code. These mutations can disrupt the normal functioning of cells and lead to uncontrolled growth, which is a hallmark of cancer. Therefore, exposure to carcinogens can increase the risk of developing cancer by causing mutations in our cells.
Are gamete cells mutations and somatic cells mutations inheritable?
Since only gamete cells actually participate in the creation of a new organism, it is only the mutations in gamete cells which are inheritable; mutations in somatic cells are not inheritable.
Why aren't somatic mutations passed on to the next generation?
Somatic mutations occur in non-reproductive cells and are not passed on to offspring because they do not affect the germline cells (sperm and eggs) that give rise to the next generation. Only mutations in the germline cells can be inherited by offspring.
Why are cancer cells able to divide quicker than normal cells?
Cancer cells can divide quicker than normal cells because they have mutations in their DNA that allow them to ignore the signals that control cell division. This uncontrolled growth is a key characteristic of cancer.
