Organization & Inheritance of Viral Genomes

Flashcards for core concepts related to the organization and inheritance of viral genomes.

The genome of viruses may be or in nature and can be single-stranded or double-stranded.

DNA; RNA

Examples of diseases that arise from gene mutations include and .

sickle cell anemia; cancer

Viral genomes are stored and passed on to subsequent generations through .

DNA

Influenza virus is classified as a virus because it has a segmented linear (-) RNA genome.

enveloped

During the reproductive cycle of a virus, the phase where new viral particles are formed is known as .

Assembly and Release phase

Viruses require cells to reproduce, as they lack metabolic enzymes and organelles necessary for replication.

host

Viral infections can cause disease in the host by disrupting host tissues and functions, referred to as .

viral infections cause diseases

The two mechanisms by which genetic variation in viruses arises are called and .

antigenic drift; antigenic shift

The lytic cycle of T4 bacteriophage leads to the of the host cell.

death

The phase where a viral genome integrates into the host genome during lysogenic cycle is known as .
