Ribosomes provide the scaffolding on which trnas interact with mrna during translation of an mrna sequence to a chain of amino acids. a ribosome has three binding sites, each of which has a distinct function in the trna-mrna interactions. drag the appropriate trnas to the binding sites on the ribosome to show the configuration immediately before a new peptide bond forms. if no trna is bound to a site at that time, leave that binding site empty.

the answer is b.) hydrogen bonds between bases.

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.
