What is the DNA -> RNA process? - RNA polymerase I creates a transcript. This is primary RNA with 5' cap and 3' with poly(a) site. Maturation of RNA includes cleaving at the poly(a) site and RNA splicing of introns to leave matureRNA. What is the mRNA to protein process? - Codons run through ribosome in 3 base pairs. A corresponding tRNA recognises 3 base pair and brings with it conjugate bases and an AA. This adds the relevant AA for every 3 base pair, creating a polypeptide. What is...

CEM 142 MOCK EXAM 2 QUESTIONS AND ANSWERS ALREADY PASSED Imagine a reaction in which compound A (which is a blue compound) reacts with compound B (which is a yellow compound) to give AB. A2 + B2 --> 2AB What can you say about the color of compound AB? It is impossible to predict what the color of AB is from the information given Which acid is the strongest of CH4 NH3 OH2 and HF HF because H and F are small atoms - more bond overlap, not willing to share electrons, most positive ...

intermolecular forces - forces between molecules EX: HCl-HCl intramolecular forces - hold atoms together in a molecule Ex: H-Cl Types of intramolecular forces - 1. Ionic 2. Covalent - Polar covalent - nonpolar covalent nonpolar covalent bond - bond between atoms with same electronegativity polar covalent bond - bond with unequal sharing of electrons the lower the pka the - stronger the acid Buffers are ___ - solutions that resist changes in pH when strong acids or bases ...

Hydrophobic Effect correct answers _________ is the enthalpic and entropic energies contribute to the net free energy of stabilization of globular proteins. Mass Action correct answers The following equation is the analytical version of the principle of __________________________. ΔG = ΔG'o + R T lnQ, where Q = [C'][D'] / [A'][B'] Partition coefficient [It is a perturbation to the poise/balance of the participants in an equilibrium. (Take this into account to understand a...

Chem Exam 3 Things to Know 100% Verified Review Solution 2024/2025 Before starting a titration equation, what do we need to find? - ANS-Ka/Kb (given the other), volume, concentration of acid and base, initial mols of weak acid/base at the starting point of a titration, how do you find pH? - ANS-use a RICE table to find K expression equation, plug initial (not titrant) concentration into table and when you have K expression, solve for X. take -log of x for pH at the buffer region of a ti...

"Proton hopping" essentially means that: A) an individual proton "jumps" from one electronegative group to the next. B) a free proton moves from one hydroxyl group of ionized water to the next. C) several protons move between hydrogen bonded water molecules causing the net movement of a photon over a long distance in a short time. D) individual protons are freer to move among and between water molecules in solution. E) hydronium ions are freer to move among and between water molecules ...
