Mutations can occur in cells due to several factors, including errors during DNA replication, which can lead to incorrect nucleotide incorporation. Environmental influences, such as exposure to radiation or chemicals, can also damage DNA and result in mutations. Additionally, biological processes like viral infections or the action of mobile genetic elements can introduce changes to the genetic material.

What are three 7th grade reasons cells divide?
cells divide because of: -growth -development -repair
When is chill is born with trisomy when did the mutation occur?
Trisomy occurs when there is an extra chromosome present in the cells, typically due to an error in cell division during the formation of sperm or egg cells. This mutation can happen during meiosis, the process of cell division that produces gametes, leading to a fertilized egg with three copies of a chromosome instead of the usual two. In the case of Down syndrome (trisomy 21), for example, this error occurs during the formation of the egg or sperm, and the exact timing can vary, but it generally happens before conception.
In what type of mutation is one base left out?
A one base left out mutation is called a deletion mutation. This type of mutation involves the loss of one or more nucleotides from a DNA sequence, which can lead to a frameshift mutation if not in multiples of three.
What are the three reasons cell division must occur?
Cells must reproduce for growth, development, and repair.
What are the three main types of stem cells?
The three types of stem cells are Totipotent, Pluripotent and Multipotent. Edit By Camden Stevens: there are actually four- Totipotent, Pluripotent, Multipotent, and Unipotent stem cells. Toti, Pluri, and Multipotent are all embryotic stem cells, which means they occur in the embryo before the child is actually born, then pluripotent and multipotent last until adulthood. Then unipotent stem cells occur through adulthood to the rest of the life.
What are three reasons cells undergo meiosis?

What are four of chromosomal mutation?
Four types of chromosomal mutations are Down syndrome (which is a mutation in which there are three copies of chromosome 21), Kinefelter Syndrome (which is a mutation in which a male has an extra X-chromosome), Turner Syndrome (which is a mutation in which a female is missing an X-chromosome), and Patau Syndrome (which is a mutation in which there are three copies of chromosome 13).
What type of mutation causes autism?
The mutation that causes Autism is a rare genetic mutation. There are three different genes that are linked to the cause of different disorders on the Autism Spectrum.
How does genetic mutation occur?
Gene mutations may occur in at least three Ways: they can be inherited from a parent, or acquired during a person's lifetime - See Epigenetics - or acquired during a person's lifetime - see Strontium 90.
In what type of mutation is one base left out?
A one base left out mutation is called a deletion mutation. This type of mutation involves the loss of one or more nucleotides from a DNA sequence, which can lead to a frameshift mutation if not in multiples of three.
