Q. In bacteria, genes within an operon are transcribed under the control of a single promoter and the primary mRNA transcript contains sequences which can be translated into each of the independent proteins. In some cases the first gene in the linear sequence appears to be transcribed at a much […]
Question: A plant line with reduced fertility comes to the attention of a plant breeder who observes that seed pods often contain a mixture of viable seeds that can be planted to produce new plants, and withered seeds that cannot be sprouted. The breeder examines numerous seed pods in the reduced […]
An ac generator consisting of a coil with N turns rotating at angular speed “w” in an external magnetic field B produces a maximum emf E0. If you now decrease the number of turns in the coil to N/2 and at the same time cause it to rotate twice as […]
1)Describe the structure of a typical E. coli gene and how transcription would be initiated at the gene? 2)Members of the genus Mycoplasma stain Gram negative although the taxonomically grouped with Gram positive bacteria. The organism Deincoccous radiodurans grouped with the Gram negative alpha-Proteobacteria, yet it typically stains Gram positive. […]
