- Many viruses enter host cells through receptor- mediated endocytosis, What is an advantage of this entry strategy? The virus directly enters the cytoplasm of the cell The virus is protected from recognition by white blood cells The virus only enters its target host cell type The virus can directly inject its genome into the cell’s nucleus.U UUU UAU 11yr Phe UUC UUA Leu UUG Jle UCU UCC UCA UCG UGU UGC Cys UGA Stop UAG Skop UGG Trp UAC Ser UAA Stop CUU CUC CỦA CUG CAU JHis CAC CGU CGC CGA CGG CCC Leu Pro Arg ССА Delete CCA CG CAA CAG JGIN Gln AUU AUC le AUA AUG Met AGU 1 Ser AGC AGA AGGJArg 1.

The attack of a host cell is necessary for the virus to survive for all of the reasons listed EXCEPT one. That is they cannot synthesize proteins becayse they lack ribosomes and must use the ribosomes of their host cells to translate viral messenger RNA into new Eliminate proteins. A) they cannot produce or store energy in the form of ATP and have to get their energy from the host cell. B) they parasitize the host cell for basic molecules like amino acids, nucleotides, and lipids. D) they lack DNA/RNA so they must use the DNA of the host cell. Address 立
- 3. The table on the last page compares for each of four different proteolytic enzymes the chemical bonding structure of a classical substrate with the structures of two competitive inhibitors. For each substrate structure an arrow indicates the position of the scissile bond, i.e., the bond that is cleaved through catalytic action. For each enzyme, one of the inhibitors is a classical competitive inhibitor while the other is a transition-state inhibitor analog. While ordinary competitive inhibitors are associated with (dissociation) inhibitor equilibrium con- stants of ~10-3 to 10-6 M, transition-state analogs exhibit inhibitor constants ≤ 10-⁹ M. (a) For each enzyme draw a circle around those parts of the substrate that account for specificity of substrate recognition. (b) For each enzyme identify the transition-state inhibitor analog by drawing a circle around it and give a brief explanation of why it mimics the structure of the transition-state species.
