Several in cause. It could be as simple as a copying error during replication, a thymine dimer in a skin cell's DNA due to UV light, or a carcinogenic mutation of a cell's DNA as a precursor to cancer.
A mutation that makes a rabbit able to run faster.
Although the cause of barbules to form on feather barbs doesn't sound like a difficult change in evolution, it would likely take more than just a single mutation for such an evolutionary change to occur. Most likely, it would take many mutations.
The squirrel will have a heart that does not function correctly.
REINFORCED
during meiosis
the importance of DNA order is that if it does not maintain its order, a mutation will most likely occur.
A mutation in egg cells
Most of said species die, if there is a favorable mutation existent in the population that characteristic will become more prevalent. If not the species will most likely go extinct.
Victimization is most likely to occur when
A mutation that makes a rabbit able to run faster.
A stock split is most likely to occur when
mutation
A frameshift mutation, such as an insertion of one nucleotide, is most likely to produce a protein with one extra amino acid. This type of mutation shifts the reading frame of the genetic code, leading to a change in the entire sequence of amino acids after the mutation site.
Rain is the most likely type of precipitation to occur in the summer.
Tornadoes are most likely to occur in the late afternoon and earl evening.
No, glands are meant to regulate many features of the human body, like salt and/ or acids... Cell mutations can occur in various glands however, and can most likely be malignant cancers.
