The appearance of a white bacterial colony most likely resulted from?
1. Mutation Castle Learning #SWAG
What is bacterial mutation?
this is a process similar to transformation.the only difference is that it does not use a becteria as a host cell.
What are the two major mechanisms by which bacterial populations generate genetic diversity?
gene exchange and mutation :)
What is an example of a good or bad mutation?
A good mutation example is lactase persistence, where individuals can digest lactose into adulthood. A bad mutation example is cystic fibrosis, a genetic disorder that causes severe respiratory and digestive problems.
What is pleiotropism?
it refers to gene or mutation that has multiple effects like polyphenotype
A frame shift mutation occurs any time a gene mutation results in the insertion or deletion of a number of nucleotides that is not a multiple of three?
false
What is another name for the sudden appearance of a new allele?
Another name for the sudden appearance of a new allele is called a mutation. Darwin called it a sport of nature.
What is the phenotype of a mutation?
The phenotype of a mutation refers to the observable physical or biochemical characteristics of an organism that result from the mutation. It can include traits such as altered appearance, behavior, or function compared to the wild-type or non-mutated organism.
The sudden appearance of a light-colored moth in a large population of dark-colored moths was probably the result of?
A mutation
What causes the most genetic diversity in a bacterial colony?
Mutations, genetic recombination (such as through horizontal gene transfer), and selective pressures from the environment all contribute to genetic diversity in a bacterial colony. These mechanisms allow for variation in genetic material, leading to different traits and abilities that can help bacteria adapt and survive in changing conditions.
Would a point mutation or a frame shift mutation more likely produce a neutral mutation?
A point shift mutation is more likely to produce a neutral reaction. This is because it involves a change in one nucleotide. A frame shift mutation is more deleterious because it involves the insertion or deletion of multiple base pairs within a gene's coding sequence.
What is a mutation that helps an organism to live and survive in its environment?
One example of a mutation that helps an organism live and survive in its environment is the development of antibiotic resistance in bacteria. This mutation allows bacteria to survive exposure to antibiotics and multiply, leading to the continued existence of the resistant bacterial strain.
