Which numbered component in the figure to the right showing a portion of a biological membrane is involved in helping cells transfer information from the outside to the inside of the cell? A. 1 B. 2 C. 3 D. 4 E. 5 Given the general structure of an amino acid, the sequence of atoms along the peptide backbone of a tripeptide (a protein with three amino acids), starting with the carbon atom at the C-terminal, will be: A. C-N-C-O-C-N-C-O-C-N-C B. C-N-C-C-N-C-C-N-C C. C-C-N-C-C-N-C-C-N D. N-C-C-N-C-C-N-C-C E. C-O-C-N-C-O-C-N-C-O-C-N Double stranded nucleotide polymers composed of some base pairs may melt at higher temperatures than double strands composed of other base pairs. If so, which base pairs are likely to have higher melting temperatures? A. All pairings have similar melting points B. G paired with C C. A paired with T D. Any pairs in DNA are likely melt at a lower temperature than those in RNA because the nucleotides contain a smaller sugar that will melt more quickly E. A paired with U
