- You are a virologist interested in studying the evolution of viral genomes. You are studying two newly isolated viral strains and have sequenced their genomes. You find that the genome of strain 1 contains 25% A, 55% G, 20% C, and 10% T. You report that you have isolated a virus with a single-stranded DNA genome. Based on what evidence can you make this conclusion?
- Proteins produced by the immune system in response to a foreign molecule or invading microorganism are called
- Common folding pattern in proteins in which a linear sequence of amino acids folds into a right-handed coil stabilized by internal hydrogen bonding between backbone atoms is called a/an
- Loss of electrons from an atom, as occurs during the addition of oxygen to a molecule or when a hydrogen is removed is called
- Linked pair of chemical reactions in which the free energy released by one of the reactions serves to drive the other is called a/an ?
- The thermodynamic function that is related to the second law is called _____?
- Extra energy that must be possessed by atoms or molecules in addition to their ground-state energy in order to under a particular chemical reaction is called a/an _____?
- Molecule on which an enzyme acts is called a/an ?
- State at which there is no net change in a system. In a chemical reaction, this state is reached with the forward and reverse rates are equal.
- Region of an enzyme surface to which a substrate molecules binds in order to undergo a catalyzed reaction is called a/an
- A substance that releases protons when dissolved in water, forming a hydronium ion is called a/an _____?
- Most of the interactions between macromolecules could be mediated just as well as covalent bonds as by noncovalent bonds T/F
- A type of noncovalent bond that is formed at a close range between non-polar atoms is called a/an _____?
- A 10^-8 M solution of HCL has a pH of ?

- What stabilizes the single-stranded DNA (ssDNA) non-template strand at the -10 element?
- What is the complete RNA polymerase with sigma factor called?
- Many of the mechanisms that cells use for maintenance and reproduction were first studied at the molecular level in bacteria. Which bacterial species had a central role in advancing the field of molecular biology?
- Mitochondria perform cellular respiration, a process that uses oxygen, generates carbon dioxide, and produces chemical energy for the cell. Which answer below indicates a correct pairing of material "burned" and the form of energy produced during cellular respiration?
