Answer:
Mutations can occur during cell division in multiple ways. One way is through errors that happen during DNA replication, where the DNA sequence is copied, and mistakes or changes to the DNA sequence can occur. These changes can happen spontaneously or due to environmental factors such as radiation or chemicals that damage the DNA.
Another way mutations can occur is through errors that happen during mitosis or meiosis, where the chromosomes are divided and distributed to the daughter cells. Mistakes can happen during this process that results in the loss or gain of DNA segments, leading to mutations.
Finally, mutations can also occur due to the insertion of foreign DNA sequences into the chromosome, such as transposable elements or viruses. These elements can disrupt the normal DNA sequence and cause mutations.
