How can a mutation in the DNA of a cell alter its behavior in a way that distinguishes it from normal cells?
A mutation in a cell's DNA can change the way the cell functions, leading to abnormal behavior that sets it apart from normal cells. This altered behavior can result in the cell growing uncontrollably, not responding to signals to stop growing, or behaving in ways that are harmful to the body.
A point mutation occurs in a sex cell of an adult chimpanzee. The mutation is located on a gene responsible for the development of the eye. Which describes the most likely effect of this mutation?
The point mutation may lead to a change in the protein coded by the gene, potentially affecting eye development in the offspring of the chimpanzee. Depending on the specific nature of the mutation, it could result in a range of eye-related conditions, from minor changes to more significant developmental abnormalities.
A mutation in which a single base is added to or deleted from DNA is called what?
A mutation in which a single base is added to or deleted from DNA is called an insertion or deletion mutation, also known as an indel mutation. This can lead to a shift in the reading frame during translation, causing significant changes in the resulting protein sequence and potentially leading to functional consequences.
What is a process in which unregulated cell division occurs?
Cancer. The nuclei of the cells are very enlarged because they divide uncontrollably. The cancer cells take more nutrients than healthy somatic cells, but they don't perform any body functions.
How does a somatic mutation in a gene alter the function of a cell?
A somatic mutation in a gene can alter the function of a cell by changing the instructions encoded in the gene, leading to abnormal protein production or function. This can disrupt normal cellular processes and potentially contribute to diseases like cancer.
Which type of tissue would have a higher mitotic index normal tissue or cancerous tissue?
Cancer cells have higher mitotic index because they have a mutation in the DNA so they reproduce uncontrollably and therefore divide faster which means they have a higher mitotic index. ex. In a normal lung tissue, % of cells dividing is 5% while in a cancerous lung the % of cells divding is 25 %
What is the result of abnormal cell division?
mutation
How can a mutation in the DNA of a cell alter its behavior in a way that distinguishes it from normal cells?
A mutation in a cell's DNA can change the way the cell functions, leading to abnormal behavior that sets it apart from normal cells. This altered behavior can result in the cell growing uncontrollably, not responding to signals to stop growing, or behaving in ways that are harmful to the body.
What is a mutation that forms an oncogene that changes normal cells into cancerous cells?
to a gene
What are the signs of a mutation?
Abnormal cell growth and foreign side effects.
What is one possible consequence of mutation in a non-sex cell?
The formation of a tumor, which may or may not be cancerous.
What will happen when cells divide uncontrollably?
When cells divide uncontrollably it causes things like mutation or cancer, because cancerous cells go through rapid cell divisions and do not develop in the same way that healthy cells develop
Can just one mutation usually change a normal cell into a cancerous one?
yes, eg sickel celled animia
A point mutation occurs in a sex cell of an adult chimpanzee the mutation is located on a gene responsible for the development of the eye what best describes the most likely effect of this mutation?
The offspring will have abnormal eyes--APEX
Is achondroplasia caused by a mutation?
Yes, achondroplasia is primarily caused by a specific mutation in the FGFR3 gene. This mutation leads to abnormal bone growth and results in the characteristic features of achondroplasia, such as short stature and characteristic facial features.
How is cancer classified?
Cancer is classified as an abnormal growth of cells. This may happen because of a mutation in the cells DNA. When the cells grow abnormal, it usually grows too fast.
The abnormal cell function that causes cancer?
mutation, it causes cells to reproduce abnormaly fast, creating tumors
