Mutations can arise at the cellular level for a variety of reasons. The most common source of mutations is an error in the copying of genes, known as proofreading error. Mutations may also arise though the presence of a mutagen which can also cause a proofreading error. Similarly, UV light can damage the strands of DNA such that the attempt to fix the error can introduce a mutation. Finally, the chromosome itself can be the source of mutation either through breakage or anomalous linkage.

What happens to the cell during throat cancer?
Throat cancer refers to cancerous tumors that develop in your throat (pharynx), voice box (larynx) or tonsils. Cancerous tumors typically develop at the cellular level due to mutagens and carcinogens, causing mutations in DNA sequences that code for proteins that limit and monitor mitosis. This mutation leads to the lack of those proteins, causing uncontrollable mitotic divisions leading to the development of tumors.
What is respiration from the organ level to the cellular level?
According to my knowledfe Photorespiration is the respiration from the organ level to the cellular level.
Why are micro-deletions and micro-insertions difficult to diagnosis using karyotyping?
Because only the chromosomes can be seen in a karyotype, and microdeletions/insertions are mutations at the molecular level, it is virtually impossible to detect such mutations at the chromosomal level.
What happen when there are mistakes made during protein synthesis?
The ribosomes are the " workbench " of protein synthesis with the rough ER accepting some polypeptide chains from the ribosomes studding it into it's lumen for modification. Then the modified proteins are shipped to the Golgi for further modification and shipment to wherever they are needed.
How is cancer different from mad cow disease on a cellular level?
At the cellular level, mad cow disease (BSE or bovine spongiform encephalopathy) is caused by a mis-folded protein that causes other copies of the same protein to mis-fold as well. These mis-folded proteins (called prions) do not function and cannot be broken down by the cell, so they accumulate like so much cellular junk in the cytoplasm until the cell dies from inability to function. The clinical signs at the whole animal level are caused by the deaths of nerve cells. In contrast, at the cellular level cancer is caused by one or more genetic mutations that cause the cell to divide rapidly and disregard the normal intercellular signals to stop dividing. While there are sometimes significant abnormalities in protein production and function, these are a side effect of the cancer rather than the underlying cause.
What happens at the cellular level when you breathe?
explain how respiration (breathing) is related to cellular respiration in terms of equilibrium what the heck kind of answer is that it just rephrases the question
Cellular level is called?
The cellular level is the most basic level of human life. The cellular level is the beginning of structural and functional levels.

What are the Signs of aging at the cellular level?
Signs of aging at the cellular level include shortening of telomeres (protective caps on the end of chromosomes), accumulation of damage in DNA leading to mutations, decline in mitochondrial function, and increased production of free radicals causing oxidative stress. These cellular changes contribute to aging-related diseases and decline in cell function over time.
Homeostasis can occur at the cellular level or the system level?
False
An abnormal low level of oxygen at the cellular level?
Hypoxia
Is taking in water from a cup into the body osmosis?
No, it isn't. Osmosis is on a cellular level, like water moving through the membrane of a cell. However, it is a good metaphor to explain osmosis.
Why are micro-deletions and micro-insertions difficult to diagnosis using karyotyping?
Because only the chromosomes can be seen in a karyotype, and microdeletions/insertions are mutations at the molecular level, it is virtually impossible to detect such mutations at the chromosomal level.
What does cellular level organization means?
Cellular Level Organization means that the organism only contains cells... Meaning it has no tissues nor organs....
What is the second level of organization in a mulitcellular organism?
It is cellular level
What causes mutations in bacteria?
Pretty much the same process that causes mutations in any organism. The replication of the genetic code is not perfect and copying mistakes are made where one bases is substituted for another, or a whole string of bases is shifted in a frame shift. Google ' mutation. '
