What is the difference between flu viruses and the measles virus?

Influenza and measles are viruses that both cause respiratory symptoms. The typical measles rash does not appear for 2-4 days, so during influenza season, symptoms of early measles can be confused with influenza.

Explanation:

Explanation:

Vaccines for both measles and flu already exist, however the flu vaccine must be updated because of the virus's ability to change and adapt in order to invade cells in the human body. The goal of researchers was to find genes in each virus that cannot survive changes.

By comparing two similar viruses which attack the body in similar ways through the lungs, researchers confirmed that the measles virus is much less open to evolutionary change by using an experimental technique called insertional mutagenesis to change the genes of each virus.

that is wrong, its not thymus.

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.
