WebA. Mutations can spontaneously occur during DNA replication. Sometimes, during the process of replication, the DNA code is copied incorrectly, and an incorrect nucleotide is attached to the new strand of DNA. This incorrect copy is known as a B. mutation. Genes can sometimes be exchanged between homologous chromosome pairs. WebThis mutation makes the spike proteins a different completely different shape. A mutation in the gene that codes for the enzyme that copies the RNA genome of SARS-CoV-2. The mutation causes the enzyme to work at a faster rate. A mutation in the SARS-CoV-2 RNA genome that changes the RNA molecule so that the ribosomes no longer recognize it.

Mutation

WebKey points: In transformation, a bacterium takes up a piece of DNA floating in its environment. In transduction, DNA is accidentally moved from one bacterium to another by a virus. In conjugation, DNA is transferred between bacteria through a tube between cells. Transposable elements are chunks of DNA that "jump" from one place to another. WebMutation creates variations in protein-coding portions of genes that can affect the protein itself.
