Mutations can happen spontaneously when DNA is replicated incorrectly during cell division or from exposure to environmental factors like radiation or chemicals. These changes can alter the genetic code, leading to new traits that may be beneficial, harmful, or have no effect on an organism's survival.
Mutations happen in ALL living things (and also in viruses)!!!!!!
Darwin referred to individuals that expressed mutations as variations or variants in his theory of evolution.
Insertion, Deletion, and Substitution
Genetic mutations are changes that occur in the DNA sequence of an organism's genetic material. These alterations can happen in various parts of the genome, including coding regions (genes), non-coding regions, or regulatory elements. Depending on their nature and location, mutations can be harmful, neutral, or beneficial, influencing traits and potentially affecting an organism's survival and reproduction.
Mutations can have various effects on living organisms, ranging from no visible impact to causing genetic disorders or changes in physical traits. Beneficial mutations can lead to evolution and adaptation, while harmful mutations can reduce an organism's fitness or survival. The specific impact of a mutation depends on factors such as its location in the genome and the nature of the genetic change.
Most mutations occur in the DNA of an organism, specifically in the genes. Mutations are primarily random in nature, meaning they can happen spontaneously and are not typically influenced by external factors.

Mistakes in replication or separation of chromosomes can lead to genetic mutations. These mutations can result in various consequences, such as genetic disorders, cancer, or cell death. The severity of the consequences depends on the nature and location of the mutation within the genome.
mutation are caused by radiation and are 99.9% harmful

all mutations in terms of DNA happen in a gene. here it has to be noted that a gene is made up of two strands of nucleotides which are made up of amino acids. when mutations occur the sequence of nucleotides may change. sometimes a nucleotide may become missing hence the sequence of the strands change. mutations can be harmful but also very beneficial.
Many herbicides and pesticides hit the nuclear material and cause mutations when used to protect crop plants. Apart from causing mutations these very chemicals are carcinogenic in nature and cause cancer.
It is rare, but genetic mutations like this do happen sometimes.
