A strategy being considered for use in hospitals called cycling. The idea is simple: doctors in a hospital would cycle through antibiotics, prescribing a particular antibiotic for period of time and then switching to a new one. Researchers and clinicians thought that cycling would reduce levels of antibiotic resistance because the bacteria would not have time to evolve to keep up with the changing drugs — just as a resistant strain for Drug #1 evolves and spreads, along comes Drug #2, and strains resistant to Drug #1 no longer have any advantage.
Key Point #4: What is a solution to antibiotic resistance?
What can we do?

Key Point #1: DNA is your genetic information (genes)
Your DNA determines what is on the inside and the outside (the traits) Genotypes and phenotypes
Genes and physical expression of genes For example:
predisposition to cancer or eye color

Do all cells contain the same DNA?No, all cells have the same building
blocks, but the building blocks are arranged in different orders to give us
variety.

Why are homologous structures evidence for evolution?
Homologous structures are evidence that homologous organisms share a common
ancestor

are closely related.

Why is DNA used as evidence for evolution?
DNA is a valid piece of evidence for evolution because we can use DNA sequencing to determine similarities and differences between species. DNA can also account for structural similarities seen in organisms. For species that have a common ancestor and have recently undergone evolution to form a new species, will share more DNA with one another.

We can look at the similarities among species and determine they must have the same ancestor since they same building blocks.
