Study Notes
True or False Statements
- Viruses reproduce inside the cells of living hosts: True
- Viruses have cells that divide: False
- Viruses contain genes, which allow them to mutate and evolve: True
- Viruses are made of either two or three parts: True
- All viruses are covered with a protein coat to protect the genes: True
Characteristics of Viruses
- Viruses are acellular, meaning they do not have a cellular structure.
- They require a host cell to replicate and reproduce, utilizing the host's cellular machinery.
- Viral genetic material can be DNA or RNA, which enables mutation and evolution.
Origin of Viruses
- The exact origin of viruses is unclear; however, theories suggest they may have originated from cellular organisms or existed before the first cells.
- Some hypotheses indicate that viruses may have evolved from mobile genetic elements or plasmids.
Purpose of the Protein Coat
- The protein coat, or capsid, of a virus serves to protect the viral genetic material from the external environment.
- It facilitates the attachment and entry of the virus into host cells.
Virus Reproduction
- Viruses reproduce by infecting a host cell and hijacking its machinery to produce new virus particles.
- The viral replication cycle typically consists of attachment, penetration, uncoating, replication, assembly, and release.
Types of Genetic Material in Viruses
- Two main types of genetic material are found in viruses: single-stranded and double-stranded DNA or RNA.
- The type of genetic material influences the virus's method of replication and infection process.
