WebHere is a quick summary of a few of these: Substitution A substitution is a mutation that exchanges one base for another (i.e., a change in a single "chemical letter" such as switching an A to a G). Such There are many different ways that DNA can be changed, resulting in different types of mutation. Web• beneficial mutation • chromosomal alteration • frameshift mutation • genetic disorder • germline mutation • mutagen • mutation ... Cells have multiple repair mechanisms to fix mutations in DNA. One way DNA can be repaired is illustrated in Figure 7.42. If a cell’s DNA is permanently damaged and cannot be repaired, the cell is ...

WebMany types of mutation can occur in an organism’s DNA. Biologically, mutation is the change in genetic material. It can be a source of beneficial genetic variation or can have dangerous effects. Mutations can result from DNA copying mistakes made during cell division and exposure to ionizing WebA point mutation is a change in a single nucleotide in DNA. This type of mutation is usually less serious than a chromosomal alteration. An example of a point mutation is a mutation that changes the codon UUU to the codon UCU. Point mutations can be silent, missense, or nonsense mutations, as described in Table 5.8.1. Web“Antigenic drift and other mutations to the DNA of viruses are always beneficial for the virus.”(1 point) Responses No, because mutated viruses may be less likely to replicate. No, because mutated viruses may be less likely to replicate. Yes, because mutated viruses have less mRNA so they can copy and replicate faster. csj old champ dog food
