Answer

Most of these techniques, including microarray analysis and reverse transcription polymerase chain reaction (RT-PCR), work by measuring mRNA levels. However, researchers can also analyze gene expression by directly measuring protein levels with a technique known as a Western blot.

The slow accumulation of genetic changes to an influenza virus over time is referred to as _______.

Ivenika [448]

Answer:

Antigenic drift refers to the slow accumulation of genetic changes to an influenza virus over time.

Explanation:

Antigenic drift is defined as the mechanism by which viruses undergo variation. This mechanism involves the slow accumulation of mutations in the viral genes, that are responsible for coding the antibody binding sites. This leads to the formation of a new strain of virus, which can't be inhibited by the old antibodies. Due to this, the virus can easily spread the disease.

The antigenic drift occurs in the influenza A virus and also the influenza B viruses.

Therefore, Antigenic drift refers to the slow accumulation of genetic changes to an influenza virus over time.
