Can derivatives of current antimicrobials be the answer to solving infections that are treated by beta-lactams?

We discussed in class that beta-lactams have become resistant against microbes because they have developed the ability to alter protein receptors making beta-lactams unable to bind. This article discusses a new antimicrobial that would attack against Streptomyces cattleya. Penems the new development contains a "sulfur atom within the ring" allowing binding. This "high affinity for penicillin receptors" allows the halt of bacterial growth. These have been a solution with vast research in recent developments the past 25 years because it is only "slightly susceptible to hydrolysis by type I cephalosporinases."

4. In fruit flies, normal eyes (+) are dominant over small eyes (ey) and straight wings (+) are dominant over curly wings (Cy). Work the following crosses through the F2 generation, and determine the genotypic and phenotypic ratios for each generation. Assume P1 individuals are homozygous: a. +, + x ey, Cy b. +, Cy x ey, + c. +, + x +, Cy

11 Groucho, rough

9 Wild type

Are these genes linked? Is the F1 in coupling or repulsion phase. Draw out the heterozygous parents genotype on chromosomes.
