You are performing additional studies of immune responses to viruses, and have 2 strains of mice. In strain A, virus is generally cleared in two weeks. In strain B, this virus eventually kills the host. You see no differences in specific antibody responses to viral coat proteins by ELISA, so you test the ability of splenocytes from recently infected mice to proliferate by measuring uptake of tritiated thymidine in response to irradiated splenic target cells after 4 days of culture together:

1. amino acid refers to the fundamental building block of proteins, comprising of an amino group and a carboxyl group.

2. catalyst refers to any substance, which increases the rate of chemical reaction without being used up in the reaction.

3. a complex molecule containing he genetic code is dna or deoxyribonucleic acid.

4. an enzyme refers to a molecule of protein, which is unique in accelerating up a particular chemical reaction in the biological systems.

5. nucleic acid refers to an sequence of sugars, phosphates, and nitrogenous bases, for example, dna and rna.

6. a protein refers to a large, composite organic molecule comprising of a huge number of amino acids associated together with the of peptide bonds.

7. rna refers to a nucleic acid that takes part in the production of proteins.

8. substrate refers to a compound, which takes part in a chemical reaction, and is chemically modified by the reaction.
