In a mutant strain of E. coli, a tRNA that recognizes the codon 5′ CUG 3′ of normal cells has a point mutation so that it now recognizes the codon 5′ GUG 3′ while still carrying its original amino acid. Surprisingly, a missense mutation found in a protein-coding gene is […]

Q1. In accordance of the logistic growth model, what happens to the growth rate of a population as the size of the population nears carrying capacity? Q2. One of the major categories of receptors in the plasma membrane reacts by forming dimmers, adding phosphate groups, and then activating relay proteins. […]

If you set up a transformation experiment in which you mixed competent E. Coli with a new plasmid that carried a gene for GFP, but not a gene for ampicillin-resistance, what colonies would you expect to grow on an LB plate with arabinose, and no ampicillin? a. fluorescent gren colonies […]
