Question

3. Do you agree or disagree with the following statement? Explain. "Mutations conferring antibiotic resistance occur in order to protect bacteria from antibiotics." 4. How does mutation rate differ from mutation frequency? Does either affect the other? 5. Why were streptomycin-resistant mutants not detected in many or most of the cultures? 6. When streptomycin-resistant mutants were detected, why did their numbers differ, perhaps very widely, among cultures?

Answer 1

1) "mutations conferning antibiotic resistance occure inorder to protect bacteria from antibiotics."

I AGREE TO THIS STATEMENT: This is because ,Mutation changes can lead to antibiotic resistance in bacteria. Resistant bacteria can survive treatment with antibiotics that increase in number through natural selection.The changes become one of the antibiotic resistant bacteria. Some changes to make the bacteria against the antibiotic. If possible, that the face was, with the specific antibiotic is the bacterial population, so contrary to the multiplication of bacteria, it will be able to; Choose which of these antibiotics. These bacteria can lead to numbers now, and the end result is the toughest bacteria in town.

2) Mutation rate: The mutation rate is defined as the frequency of new mutations in a single gene or organism over time. One of the new rates of genetic mutation is the frequency of changes over time or concretion. Mutation rates are limited to a single constant exchange rate, and therefore there are not many different types of mutations. For kinds of personal data, mutation exchange rates.

mutation frequency: The frequency of mutations in the population is known as the mutation frequency.Mutation frequency and the mutation rates are very importantly providing the vital information about how often a mutation may be expressed in a particular genetic group or sex. There are factors affecting mutation frequency and rates that are involving in the evolutionary influences. Since,the organisms may pass mutations to their offspring by incorporating the mutation frequency and also analyzing the mutation frequency and rates of a particular species may be providing a means to adequately comprehend its longevity.

The Mutation frequency is defined as the rate of change as the change of squamous cells in a population is easily estimated. It must be distinguished from the rate of change, when an increase in events related to the rate of change at which, as events by cell division and in general are expressed. Since it can give rise to one or many cells event on the change of change of cells of the generation in which it has arisen, the relationship with the rate of frequency will change the art complex on the change of underlying.

3) streptomycin resistant mutants are not very often identified in culture.

Streptomycin resistance is often acquired chromosomally from the gene encoding changes in the S12 protein, rpsL. RRNA operons in most cases (rrn) and in an rpsL gene in the genomes of resistant bacteria to avoid streptomycin mutants in which resistance through mutations in the 16S rRNA gene. this is why it is less possible to identify it in cultures.

4) streptomycin resistant mutants were detected and their number is often varied in numbers widely in culture medias. This is because culture media used is different, the rrna mutation among the organism is different and also it is due to the change in the cell division.The streptomycin resistant mutants can give rise to one or many cells event on the change of change of cells of the generation in which it has arisen, the relationship with the rate of frequency will change the art complex on the change of underlying.
